Events

January
January 6 – For the first time since , the BBWAA elected four players to the Hall of Fame. Pitchers Randy Johnson, Pedro Martínez and John Smoltz, all in their first year on the ballot, received 97.3, 91.1 and 82.9 percent of the ballots, respectively, while second baseman/catcher Craig Biggio, in his third year on the ballot, received 82.7 percent of the votes after falling two votes short of induction in . Four players had been inducted in the 1955 voting; those players were Joe DiMaggio, Ted Lyons, Dazzy Vance and Gabby Hartnett. It is also the first time that three pitchers are enshrined in the same year, as well as the second consecutive year that three players in their first year on the ballot are inducted; Greg Maddux, Tom Glavine and Frank Thomas had been inducted in 2014.
January 20 – Max Scherzer signs a $210 million, seven-year contract with the Washington Nationals. In his five seasons with the Detroit Tigers, Scherzer had posted an 82–35 record, including a 21–3 record in , during which he won the American League's Cy Young Award. The contract is the second-largest for a pitcher, after Clayton Kershaw's $215 million, seven-year deal, which runs from 2014 to 2020. The previous highest contract for a right-handed pitcher was the $180 million, seven-year deal from 2013 to 2019, signed by Scherzer's ex-Tiger teammate, Justin Verlander.

February
February 8 :
The Perth Heat defeated the Adelaide Bite, 12–5, in the third and final game of the Australian Baseball League championship series to capture the Claxton Shield for the second straight season and the fourth time in five seasons.
The Pinar del Río club from Cuba defeated the Tomateros de Culiacán from Mexico in the finals of the 2015 Caribbean Series. It was Cuba's first Caribbean Series win since 1960.
February 11: Jackie Robinson West Little League is stripped of its 2014 LLWS United States title due to the use of ineligible players Mountain Ridge West Little League is awarded the U.S. title by default.

March
March 13 – The Boston Red Sox officially announced the signing of 19-year-old Cuban prospect Yoan Moncada. The Red Sox reached an agreement for a signing bonus of $31.5 million, the largest ever for a minor league contract. Because Boston had already exceeded its bonus pool for the 2014–15 international signing period, the team will pay a full 100 percent tax on Moncada's bonus, bringing the total cost for his services to $63MM.  On top of that, the Red Sox will now be restricted from signing any international amateur for more than $300K in the 2015–16 and the 2016–17 international signing periods. Moncada will likely start this season playing second base for Class A Greenville Drive.

April
April 5 – In the very first home opener played at Wrigley Field, the St. Louis Cardinals defeat the Chicago Cubs 3–0. Jason Heyward collects three hits in his Cardinal debut, Matt Holliday drives in two of the three Cardinal runs, and Adam Wainwright throws six innings of five-hit ball. The game is the first at the newly renovated Wrigley, which features a giant video board in left field and images of Ernie Banks, who had died in January, covering the bleachers.
April 8 – At Dodger Stadium, in the Los Angeles Dodgers' third game of the season, Adrián González hits three home runs off San Diego Padres pitcher Andrew Cashner, leading the Dodgers to a  7–4 victory over San Diego. With a home run in both of the previous two games, González becomes the first player in major league history to hit five home runs in the first three games of the season. González also becomes the third Dodger to hit a home run in each of his team's first three games (Carl Furillo and Jimmy Wynn did it in  and , respectively), as well as the first National League player to begin a season with three 3-hit games since Orlando Cepeda in .
April 10 – At Yankee Stadium, the Boston Red Sox defeat the New York Yankees 6–5 in a 19-inning, 6 hour, 49 minute marathon, but not without squandering three one-run leads to extend the game. With the Yankees trailing 3–2 with two out in the ninth, Chase Headley sends the game into extra innings with a solo home run. David Ortiz homers in the top of the 16th to give the Red Sox the lead again, but Mark Teixeira, turning 35 years old as the clock strikes midnight, homers in the bottom half of the inning. In the 18th inning, the Red Sox take the lead again as Pablo Sandoval singles in Dustin Pedroia, only for the Yankees to again tie the game as Carlos Beltrán doubles home John Ryan Murphy. The Red Sox take the lead for a fourth time as Xander Bogaerts scores on a Mookie Betts fly ball, then turn a double play on a Garrett Jones ground ball to end the game at 2:13 AM. The game, which also features a 12th-inning power outage that delays the game for 16 minutes, is the longest by time in Red Sox history, and the second-longest for the Yankees, who defeated the Detroit Tigers in 22 innings in a June 24,  game that lasted an even 7 hours. It is also the longest game in the Yankees-Red Sox rivalry since the Yankees defeated the Red Sox in the second game of an August 29,  doubleheader that lasted 20 innings.
April 12 – At Anaheim Stadium, Angels first baseman Albert Pujols hits his 522nd career home run off Kansas City Royals pitcher Yordano Ventura, breaking a tie with Ted Williams, Willie McCovey and Frank Thomas for 18th place on the MLB career list. The blast is not a factor in the decision, however, as the Royals prevail by a score of 9–2 and sweep the Angels. Pujols is now 12 home runs shy of tying Jimmie Foxx, who sits in 17th place on baseball's all-time home run list with 534.
April 13 :
Boston Red Sox young leadoff hitter and center fielder Mookie Betts thrills his teammates and the capacity crowd at the home opener in Fenway Park and starts the Red Sox toward a 9–4 win over the Washington Nationals. Betts walks and adds a pair of stolen bases on one play in the second half of the first inning; he successfully steals second base, then continues on to third when no one is able to cover due to an infield shift. He scores the go-ahead run on a single by David Ortiz. Then Betts belts a three-run home run in the second inning and drives in another run in the third on a well-placed infield single. Additionally, Betts robs Bryce Harper of a home run in the first, leaping against the right-center field wall to save two runs. The 22-year-old Betts smashes his second homer of the season off Jordan Zimmermann. His first blast came off Philadelphia Phillies' Cole Hamels in the Opening Day at Citizens Bank Park.
Stephen Drew hits a pinch-hit grand slam off Baltimore Orioles pitcher Tommy Hunter in the seventh inning to propel the New Yankees to a 6–5 victory at Camden Yards. With his effort, Drew joins Don Baylor, Johnny Damon and Babe Ruth as the only players to hit a grand slam for both the Yankees and the Red Sox.
April 15– In the ninth annual Civil Rights Game—played on Jackie Robinson Day—the Los Angeles Dodgers defeat the Seattle Mariners, 5–2, at Dodger Stadium in Los Angeles.
April 17 – Mike Trout collects his first multi-home run game of the season, a two-run homer in the sixth inning and a three-run shot in the eighth, that carries the Anaheim Angels to a 6–3 victory over the Houston Astros at Minute Maid Park. At 23 years, 253 days of age, Trout becomes the youngest player ever to record 100 home runs and 100 stolen bases in major league history.
April 22 – Boston Red Sox designated hitter David Ortiz continues his climb through the game's record book ranks in the 7–5 defeat to the Tampa Bay Rays at Tropicana Field. Ortiz delivers a fifth-inning solo home run off pitcher Nathan Karns, which moves him past Joe DiMaggio into 46th place on the MLB Career RBI List with 1,538, and also breaks a tie with Chipper Jones for 32nd place on the homer list with his 469th home run.
April 23 – The New York Mets tie a franchise season record of eleven straight wins, and for the first time in its 54-year history win ten straight homestand games, becoming the seventh major league team since  to win at least 10 straight homestand games.
April 28 – For the second consecutive day, the scheduled game between the Baltimore Orioles and the Chicago White Sox at Camden Yards is postponed. The series opener between the two teams was postponed a day in advance, after protests in the area around Camden Yards turn violent. The teams will play the third game of the series in front of an empty stadium because the game will be closed to the public. The Orioles consulted with Major League Baseball and local and state officials about the best way to move forward in the midst of violent protests following the death of Freddie Gray, a 25-year-old man who suffered a spinal injury while in police custody earlier in the month. Baltimore was declared to be in a state of emergency and the National Guard was summoned to help restore peace. As a result, the Orioles will also play their three-game series against the Tampa Bay Rays, scheduled for May 1–3, at Tropicana Field, while serving as the home team. Additionally, the postponed games between the Orioles and the White Sox will be made up as part of a single-admission doubleheader on May 28 at Camden Yards.
April 29 – Chris Davis hits a three-run homer in a six-run first inning and the Baltimore Orioles beat the Chicago White Sox, 8–2, in a fanless stadium. The gates at Camden Yards were locked because of concern for fan safety following recent rioting in Baltimore. As a result, the game is played before members of the media in the press box and 45,968 empty forest green seats. This is the first game held behind closed doors in the 145-year history of the major leagues.

May
May 1 :
Major League Baseball emails all 30 teams to announce that, effective following this year's draft, players selected in the amateur draft will be available for trade beginning the day after the conclusion of the World Series. The change is a revamp of the previous iteration, which had prohibited clubs from trading players for one year after being drafted. With the new deadline in effect, things should be much easier for teams and players going forward.
At Fenway Park, Alex Rodríguez of the New York Yankees hits his 660th career home run to tie Willie Mays for fourth place on the all-time home run list. Pinch-hitting for Garrett Jones in the eighth inning, Rodríguez lines a 3-0 pitch by Junichi Tazawa over Fenway's Green Monster to break a tie and give the Yankees a 3–2 victory over the Boston Red Sox.
Due to safety concerns as a result of the Baltimore riots, the Orioles three-game series against the Rays is moved from Orioles Park at Camden Yards to Tropicana Field with the Orioles acting as the home team.
May 3 :
The Milwaukee Brewers dismiss manager Ron Roenicke after a 7–18 start, ending his tenure with the team after four-plus seasons. Roenicke had been hired by the Brewers before the 2011 season and found immediate success. In his first year at the helm, Roenicke guided the Brewers to a franchise-best 96–66 record and first place in the National League Central. Milwaukee won its first-round NLDS matchup with the Arizona Diamondbacks but fell to the division-rival St. Louis Cardinals in the pennant series. That season earned Roenicke a second-place finish in the NL Manager of the Year voting, but that success proved hard to replicate. The Brewers slumped to an 83–79 record in 2012, while the 2013 edition dropped below .500 with a 74–88 mark. The Brewers then led the division from the 2014 season's first week all the way through the end of August, but the team went 9–17 over the final month of the year, going from one game up in the Central on August 30 to finishing the season eight games back of the eventual division champion Cardinals, and six games back in the NL Wild Card. Ultimately, Roenicke finished his time at Milwaukee with a 341–331 record.
The surprising Houston Astros won their 10th straight game, boosting the best record in the American League by beating the Seattle Mariners, 7–6, at Minute Maid Park. At 18–7, Houston set a team record for its best mark through the first 25 games. The Astros are coming off a 70–92 season, which followed three straight years of at least 106 losses. Not only do the Astros have the best 25–game start in franchise history, they tied for the fourth-best start in major league history, being surpassed only by the 19–6 record shared by the 1899 St. Louis Perfectos, the 1978 Oakland Athletics, and the 1993 Philadelphia Phillies.
May 4 – Milwaukee Brewers general manager Doug Melvin announces Craig Counsell as the new manager of the team, less than 24 hours after dismissing Ron Roenicke. A Milwaukee area native, Counsell spent six seasons of his 16-year major league playing for the Brewers. Counsell also scored the winning run for the Florida Marlins in the 11th inning of Game 7 of the 1997 World Series, and was named MVP of the 2001 NLCS as a member of the eventual 2001 World champions Arizona Diamondbacks. Counsell had been Melvin's special assistant since 2012 and was among the candidates last offseason to succeed Joe Maddon as Tampa Bay Rays' manager.
May 5 :
At Citi Field, Bartolo Colón of the New York Mets defeats the Baltimore Orioles, 3–2, to become the first pitcher to defeat the same opponent while pitching for seven different teams. He strikes out nine and walks none in  innings, having been pulled after having a shutout broken up by a Manny Machado home run. Colón had also defeated the Orioles while playing with the Cleveland Indians, Chicago White Sox, Los Angeles Angels of Anaheim, Boston Red Sox, New York Yankees and Oakland Athletics.
Carlos Pérez hits a walk-off home run at Angel Stadium in his first major league game, as the Anaheim Angels snap their four-game skid with a 5–4 victory over the Seattle Mariners. The 24-year-old rookie catcher from Venezuela, who also singled in his first major league at-bat, becomes only the fourth player to belt a game-ending home run in his big-league debut since 1900, joining countryman Miguel Cabrera (2003), Josh Bard (2002) and Billy Parker (1972). The Angels acquired Pérez from the Houston Astros in the offseason and promoted him while he was batting .361 for the Triple-A Salt Lake Bees.
May 6:
At Nationals Park, Bryce Harper hits three home runs in the Washington Nationals' 7–5 victory over the Miami Marlins. The home runs, all off Tom Koehler, come in his first three trips to the plate: a solo shot in the second inning, with a runner on base in the third, and with the bases empty in the fifth. Harper becomes the fourth player in Nationals history to hit three homers in one game, joining Alfonso Soriano, Adam Dunn and Ryan Zimmerman in ,  and , respectively.
In the Minnesota Twins' 13–0 home victory over Oakland, outfielder Eddie Rosario becomes the twenty-ninth player in history to hit a home run on the first major league pitch he sees.
May 7:
The Boston Red Sox announce that Juan Nieves is relieved of his duties as pitching coach, after presiding over a struggling pitching rotation that posted a 5.54 ERA through 28 starting appearances, the worst mark in the 15-team American League. The Red Sox starters have failed to complete the fifth inning in seven of 28 games and have combined to throw only  innings, the sixth-lowest total in the league. Additionally, the Red Sox sport a collective 4.86 ERA, the second highest in the major leagues (the Colorado Rockies have the highest at 5.38). Nieves joined the Red Sox prior to the 2013 season, and he helped lead the resurgence of starters Jon Lester (15-8), Clay Buchholz (11-1) and Félix Doubront (11-6) en route to the 2013 World Series championship. Overall, the staff posted a 3.79 ERA in 2013, the lowest mark for the club since 2002 (3.75 ERA), and also set a single-season franchise record with 1,294 strikeouts.
At Yankee Stadium, Alex Rodriguez of the New York Yankees overtakes Willie Mays for the sole possession of fourth place on the all-time home run list. In the third inning of the Yankees' 4–3 victory over the Baltimore Orioles, Rodriguez hits a Chris Tillman changeup for his 661st career home run. Rodriguez nearly homered in the first inning, but was robbed by right fielder Delmon Young, who made a leaping catch in front of the stands.
Top New York Mets prospect Noah Syndergaard pitches eight strong innings and falls a triple shy of hitting for the cycle, as Triple-A Las Vegas 51s win their 14th straight game in an 8–2 victory over the host Albuquerque Isotopes. In five games, Syndergaard improves to a 3–0 record with a 1.82 ERA and 34 strikeouts in  innings for Las Vegas. He eventually makes his major league debut with the Mets on May 12.
May 8 – Bryce Harper slugs two more home runs and drives in five runs, as the Washington Nationals beat the visiting Atlanta Braves, 9–3. Harper again uses the long ball multiple times a game after hitting three home runs with five RBI against the Florida Marlins. According to the Elias Sports Bureau, Harper became the first player in Nationals/Expos franchise history to hit five home runs in two games. The last player to do it in the major leagues was Josh Reddick of the Oakland Athletics, who accomplished the feat on August 9–10, 2013. At age 22, Harper, is also the youngest player to hit five homers within two games. The previous mark was set by Mark McGwire at age 23.
May 9 – Bryce Harper continues his torrid home run pace with a dramatic two-run, walk-off shot in the ninth inning to send the surging Washington Nationals to an 8–6 victory over the Atlanta Braves. Harper's home run is his sixth in three games, and the third walk-off of his career, while the Nationals collect their ninth victory in 11 games and improve to a 16–15 record to break the .500 mark for first time in this season.
May 10 – This is the 10th year that Major League Baseball partners with Louisville Slugger to produce the special pink bats, which usually are auctioned off to raise money for breast cancer charities. Additionally, players also show their support by wearing the symbolic pink ribbon, as well as pink wrist bands, bracelets, cleats and necklaces. As a result, the annual Mother's Day pink celebration around the MLB ballparks bring about memorable moments for baseball fanatics and ballplayers, particularly for some pitchers.
The 41-year-old Bartolo Colón holds the Philadelphia Phillies to a pair of runs, before giving up a pair of hits to lead off the seventh inning and end his day in the New York Mets 7–4 victory at Citizens Bank Park. As he has done all season, Colón gives his team enough effort to win, becoming the first pitcher to reach six wins in 2015. Colón also extends his club record of games without issuing a walk to six straight and  innings, as he has walked only one batter in  innings of work. Colón, whose mother Adriana died last August, is the only starting pitcher not wearing cleats with pink laces or highlights in honor of Mother's Day. Nevertheless, he let his performance to do the tribute to his mom.
At Safeco Field, Félix Hernández of the Seattle Mariners records his 2,000th career strikeout after striking out Sam Fuld in the fifth inning of a 4–3 victory over the Oakland Athletics. Only Walter Johnson, Sam McDowell and Bert Blyleven, who were all 28 when they struck out 2,000, reached the milestone at a younger age than Hernández at 29 years, 32 days old. Hernāndez improves to 6–0 and ties with Bartolo Colón for the most wins in the season, while his eight strikeouts on May 4 against the Angeles Angels push him past the 1,988 strikeouts of Johan Santana to give him the most by a Venezuelan-born pitcher. Hernández was the fourth-youngest to reach 1,000 strikeouts on August 25, 2010.
New York Yankees pitcher Michael Pineda has the most notable achievement of his career, dominating the visiting Baltimore Orioles over seven innings with a career-high 16 strikeouts. Pineda strikes out the side in the second and fifth innings, and records at least two strikeouts in every inning he pitches. He is removed from the game after throwing 81 of his 111 pitches for strikes, and the Yankees beat the Orioles 6–2. Pineda's strikeouts tie the most by a Yankees right-hander, and leaves him two shy of tying the club record set in 1978 by the lefty Ron Guidry. The 16 strikeouts also matches the most any major league pitcher has had in a seven-inning outing.
Texas Rangers pitcher Wandy Rodríguez sets a club record by retiring 34 straight hitters over two games. The  record comes against the visiting Tampa Bay Rays, as Rodriguez retires the first 15 hitters he faced. The Rangers prevail, beating the Rays 2–1, even though Rodríguez gets a no decision. The streak started on May 5 when Rodríguez retired the last 19 batters he faced in a 7–1 Rangers victory over the Houston Astros. Rodríguez was credited with the win in that game. The previous record was held by Kenny Rogers, who retired 28 in a row in 1994, including his perfect game against the California Angels.
May 13 – At Progressive Field, Corey Kluber of the Cleveland Indians ties Bob Feller's 77-year franchise record by striking out 18 St. Louis Cardinals in the Indians' 2–0 victory, his first win of the season in eight starts. The reigning American League Cy Young Award winner, Kluber, 0-5 entering this game, also has a no-hitter broken up with two out in the seventh on a Jhonny Peralta single. This will be the only hit Kluber allows in eight innings; he is relieved by Cody Allen, who records his fifth save of the season. Feller had struck out 18 Detroit Tigers on October 2,  in the first game of a doubleheader; however, the Tigers defeated the Indians 4–1.
May 15 :
Adrián Beltré of the Texas Rangers hits his 400th career home run in the first inning of the Rangers' 8–3 loss to the visiting Cleveland Indians. The 36-year-old Beltre jumps ahead of Miguel Cabrera, Andrés Galarraga and Al Kaline at 399 homers, as he becomes the 52nd big leaguer to hit 400. In his 18th season, Beltré ranks fourth among active players behind Alex Rodríguez (663), Albert Pujols (526) and David Ortiz (470).<ref>Adrian Beltre hits his 400th career home run CBSSports.com.

Houston Astros prospect Jon Singleton continues his powerful display at the plate with his third grand slam in five games, and the Triple-A Fresno Grizzlies roll to an 8–3 victory against the Albuquerque Isotopes at Isotopes Park. Two days before, Singleton capped a four-hit game with a slam, a two-run homer, and a franchise record of 10 RBI in the Fresno 17–6 win against the Isotopes. In his five-game stint, Singleton batted .381 (8-for-21) with five home runs and 23 RBI, while leading all of Minor League Baseball with 12 home runs and 40 RBI. Eight of his 12 home runs have come in his last 11 games, and he is 5-for-7 with three homers and 17 RBI with the bases loaded at this point in the 2015 season.Scorching Singleton belts another slam MiLB.com.

MLB and the independent Atlantic League of Professional Baseball (ALPB) sign a formal written agreement which explicates the rules that the ALPB would follow in selling its players' contracts to MLB clubs and their affiliates. This is a watershed moment for independent baseball because, although MLB clubs have routinely bought players from independent leagues, this marks the first time that MLB, which has enjoyed a U.S. Supreme Court-granted antitrust exemption since 1922, had made any formal agreement with or acknowledgment of an independent baseball league.
May 16 – Miguel Cabrera of the Detroit Tigers hits his 400th career home run, a solo shot off St. Louis Cardinals pitcher Tyler Lyons in the first inning, as the Tigers go on to beat the Cardinals, 4–3, in 10 innings at Busch Stadium. Cabrera moves to 53rd place for most career home runs in MLB history. Cabrera, who passed Tigers legend Al Kaline, becomes the second player to join the club in as many days. Texas Rangers third baseman Adrián Beltré hit his 400th on May 15. The home run also moved Cabrera past Andrés Galarraga on the home run list, making him the all-time home run leader among MLB players born in Venezuela.Tigers' Miguel Cabrera hits his 400th home run Detroit Free Press.

Atlanta Braves pitcher Shelby Miller holds a no-hitter through  innings until Miami Marlins first baseman Justin Bour breaks up the no-hit bid with a sharp single up the middle. Dee Gordon follows with an infield single before Miller retires Martín Prado on a pop-up for the final out. Miller notches a 6–0 shutout over the Marlins at Marlins Park. Miller, who struck out four, improves to 5–1 in the season with a 1.33 ERA in eight starts. It is the third time in his career that he started and pitched the first five innings of a game without a hit.

The Miami Marlins announce that manager Mike Redmond is relieved of his duties. Bench coach Rob Leary is also dismissed. The announcement comes after the Marlins were nearly no-hit in a 6–0 loss to the Atlanta Braves that completed a three-game sweep at Marlins Park. At this point, the Marlins have lost nine of their past 13 games and are fourth in the National League East with a 16–22 record. Marlins owner Jeffrey Loria, notorious for not being extremely patient with managers, fired Jeff Torborg after an identical record of 16–22 in 2003. His replacement Jack McKeon then led a turnaround that resulted in an improbable run to the 2003 World Series title. Along with the early-season firing of Torborg, Loria dismissed Fredi González in June 2010, and fired Joe Girardi and Ozzie Guillén after one season each. Redmond posted a 62–100 record in his first year as a major league manager with the Marlins in 2013, as the club improved to 77–85 in 2014, ending a streak of three consecutive last-place finishes in the NL East. Their 15-win improvement tied for the best in the NL by a 100-loss team since 1986. On the final day of last season, Redmond's contract was extended two years through 2017, while Guillén is in the final year of his four-year contract, which means the team will be paying three different managers in this season.Marlins dismiss manager Redmond  MLB.com.

May 18  – The Miami Marlins officially announce that general manager Dan Jennings will succeed Mike Redmond as the team's new manager for the remainder of the season. In other internal decision, Mike Goff will be the club's new bench coach, while VP/assistant GM Mike Berger will assume Jennings' former front office roles. Jennings has no dugout experience, but he is a respected baseball mind throughout the industry. At this point, the Marlins are still paying Jennings' GM predecessor, Larry Beinfest. They will also pay Redmond through the 2017 season and pay former manager Ozzie Guillén through the end of the current season. As a result, the move from GM to manager for Jennings will prevent the team from taking on a financial commitment to a third manager, though it is not directly clear how large a role that factor played in the decision. Owner Jeffrey Loria was not present for the press conference.
May 19 – Ryan Zimmerman smashes a two-run, game-ending home run with two outs in the 10th inning, lifting the Washington Nationals to an 8–6 comeback victory over the New York Yankees at Nationals Park. Zimmerman hits his shot off Yankees closer Andrew Miller, who had not allowed a run in  innings this season. Zimmerman's 10th career walk-off homer ties him with eight other players for 10th on the all-time list, which is topped by Jim Thome at 13. Additionally, 5.3% (10 of 189) of his career home runs have been walk-offs, the highest percent of HRs via walk-off among 819 players in MLB history with at least 100 career HRs, according to the Elias Sports Bureau.

June 3 – In a six-player transaction, the Seattle Mariners acquire outfielder Mark Trumbo and pitcher Vidal Nuño from the Arizona Diamondbacks in exchange for catcher Welington Castillo, pitcher Dominic Leone, and minor league prospects Gabby Guerrero and Jack Reinheimer.

The 29-year-old, ambidextrous pitcher Pat Venditte makes his major league debut with the Oakland Athletics. Venditte had spent eight seasons in the minor leagues before getting his first call to the majors. The Athletics lose to the Boston Red Sox 2–4 at Fenway Park, even though the switch-pitcher was not a factor in the decision. The pitcher must declare which hand he will be throwing with and must do that to the batter for the whole at bat. This matters most for switch hitters. As a result, Venditte pitches a nearly perfect 7th inning, retiring lefty Brock Holt with his left arm, then switching to his right to face righties Hanley Ramírez and Mike Napoli. He allows a single to Ramírez, but Napoli hits a double play to end the inning. In the 8th, Venditte retires Xander Bogaerts on a ground ball and strikes out Mookie Betts. He then declares that he will pitch right-handed against switch-hitter Blake Swihart, so Swihart elects to bat left-handed. Swihart strikes out swinging. Since the New York Yankees selected Venditte in the 20th round of the 2008 MLB draft, he became one of the more intriguing stories in the minor leagues. A switch-thrower since age three, Venditte uses a special glove that can be used on either hand and can be easily switched from hitter to hitter. After spending seven seasons in the Yankees system, Venditte signed with the Athletics as a minor league free agent during the postseason. Venditte became the second pitcher in MLB's modern era since Greg A. Harris with the Montreal Expos on September 28, 1995, to throw with both arms in the same game.Ambidextrous Venditte hurls two shutout frames  MLB.com. Retrieved on June 6, 2015.

Throwing 134 pitches in pitching his first complete game in the majors, he strikes out 10 and walks three in his third start for the Astros since being traded from the Milwaukee Brewers on July 30. The no-hitter also foils Chase Utley's Dodger debut; Utley, who had been traded two days earlier from the Philadelphia Phillies, for whom he had played since , goes 0-for-4. The no-hitter is the Astros' first since the combined six-pitcher no-hitter against the New York Yankees on June 11, , and their first complete game no-hitter since Darryl Kile on September 8, .
August 26 – For the second time in his career, Justin Verlander of the Detroit Tigers has his bid for a third career no-hitter broken up in the ninth. In the Tigers' 5–0 victory over the Los Angeles Angels of Anaheim at Comerica Park, Chris Iannetta, who entered the game batting .186, breaks up the bid by lining a doubleinches inside the third base line; the hit is the only one Verlander will allow. Verlander, who no-hit the Milwaukee Brewers on June 12,  and the Toronto Blue Jays on May 7, , was bidding to become the sixth pitcher to throw three or more no-hitters, joining Larry Corcoran (three in the 1880s), Cy Young (three), Bob Feller (three), Sandy Koufax (four) and Nolan Ryan (seven). Besides, Verlander also had a no-hitter broken up in the ninth against the Pittsburgh Pirates on May 18, .
August 28 – The Seattle Mariners announced that general manager Jack Zduriencik had been relieved of his duties, effective immediately. Zduriencik was hired as Seattle's GM in October 2008 after a decade with the Milwaukee Brewers, where he was regarded as a top talent evaluator. Over his seven seasons in charge of baseball operations in Seattle, the Mariners finished with a winning record just twice and never qualified for the postseason. Assistant GM Jeff Kingston will assume Zduriencik's responsibilities on an interim basis through the end of the season, according to the team.

David Ortiz hit his 494th career home run in the 5–4 loss to the New York Mets at Citi Field. That moves Ortiz into sole possession of 27th place on the all-time home run list, ahead of Lou Gehrig and Fred McGriff at 493. Ortiz is now 10 home runs short of tying Eddie Murray 26th place on MLB's career home run list.
At Dodger Stadium, Jake Arrieta of the Chicago Cubs no-hits the Los Angeles Dodgers 2–0. He strikes out a season-high 12 batters, including all three he faces in both the first and ninth innings, in pitching the Cubs' 14th no-hitter and their first since Carlos Zambrano in . Sandy Koufax had been the last pitcher to complete a no-hitter by striking out all three batters he faced in the ninth inning, doing so in his perfect game against the Cubs on September 9, —a game also played in Dodger Stadium. Arrieta receives the benefit of a close call from the official scorer on Kiké Hernández's third-inning ground ball, which Cub second baseman Starlin Castro tries to play on a short hop; the ball bounces off Castro and rolls away for what the official scorer rules an error. The Dodgers, no-hit by Mike Fiers of the Houston Astros nine days earlier, become the first team to have two no-hitters pitched against it in one month since the Cincinnati Reds in June, . The nine-day span is also the shortest between no-hitters pitched against a team since the 1923 Philadelphia Athletics were no-hit twice in three days. The no-hitter is the third to be pitched against the Dodgers at Dodger Stadium; they had also been on the losing end of Dennis Martínez's perfect game in , and Kent Mercker's no-hitter .Dodgers silenced by Jake Arrieta in second no-hitter in 10 days.

September
September 3 – The Washington Nationals crushed the Atlanta Braves, 15–1, at Nationals Park. Bryce Harper made history, as he scored four runs for the Nationals, even though he statistically did not have an at-bat but drew a walk in each of his four plate appearances. Only three other big leaguers have ever scored four runs and received four walks in a game without taking a turn at-bat: Larry Doby (1951), Joe Morgan (1973) and Rickey Henderson (1989). Besides, Harper worked a bases loaded walk and was credited with a run batted in, which is the first time in modern history that a hitter has drawn at least four walks, scored four times, and drove in a run without having a hit in each of his turns at-bat.
September 4 – At Wrigley Field, Addison Russell of the Chicago Cubs became the first position player in National League history to hit two home runs in the same game while batting ninth in the order. The home runs came in the second and fourth innings, both off pitcher Zack Godley, in the Cubs' 14–5 victory over the Arizona Diamondbacks. At 21 years, 224 days old, Russell also became the youngest Cubs player to hit two home runs in the same game since Danny Murphy did so at 19 years, 35 days old on September 27, .
September 10 – The Philadelphia Phillies announced that they would not extend the contract of general manager Rubén Amaro Jr. Amaro, 50, rose from team batboy between 1980 and 1983 to playing for the Phillies during five seasons spanning 1992–1998. Amaro rejoined the Phillies in the 2008 offseason, when he succeeded GM Pat Gillick. The Phillies won the 2009 National League pennant and made a World Series run in Amaro's first full year as GM, ultimately coming up short to the New York Yankees, and went on to reach the postseason in the 2010 and 2011 campaigns as well. However, a number of transactions made by Amaro that were aimed at keeping the Phillies in contention served, instead, to only deplete its minor league system while failing to pay significant on-field dividends.
September 12 – David Ortiz connected his career 500th home run against Tampa Bay Rays pitcher Matt Moore in the fifth inning, sending a 2-and-2 curveball to right-center field at Tropicana Field. It was the second home run of the game for Ortiz, the 50th time he has hit multiple home runs in a game. Ortiz also has hit 443 of his home runs as a designated hitter, a major league record at that position. In addition, he now ranks 27th in major league history and 12th in American League history in home runs, as well as 11th among lefthanded batters and fourth among players from the Dominican Republic. His next milestone will be moving up the Boston Red Sox all-time list, which is led by Ted Williams with 521 home runs followed by Carl Yastrzemski with 452. At the time, Ortiz has 442.
September 15 – Stephen Strasburg gave up one hit and tied a career best with 14 strikeouts in eight dominant innings, as  the Washington Nationals beat the Philadelphia Phillies, 4–0, at Citizens Bank Park. Bryce Harper hit two home runs and drove in all the runs, while collecting his 10th career multihomer game and fifth this season. The 14 strikeouts matched Strasburg's career high, which came in his first career start against the Pittsburgh Pirates on June 8, 2010, joining Bill Stoneman as the only Nationals/Expos franchise pitchers to strike out at least 14 hitters twice.
September 16 – Jake Peavy led the San Francisco Giants to a 5–3 victory over the Cincinnati Reds at AT&T Park, posting a solid outing and helping himself with the bat. The veteran right hander allowed two runs on seven hits over six-plus innings, striking out eight batters and walking just one. Peavy also blasted his career third home run off Collin Balester in the fourth inning, to become the fifth Giants pitcher this season to hit a home run, matching a major league record. Not until he got past second base and saw an umpire signal did Peavy know he had cleared the fence. Peavy is legally blind and with contacts can only get to 20-40 vision.  The Giants starting rotation has hit nine homers, one shy of the single-season franchise record set in 1924 and matched in 1934. Madison Bumgarner has collected five, and Mike Leake, Tim Hudson, Ryan Vogelsong and Peavy have one apiece.
September 20 – Kansas City Royals DH Kendrys Morales enjoyed what might have been the best offensive game of his major league career, hitting three solo home runs in a 10–3 win over the Detroit Tigers at Comerica Park. Morales also hit a triple, scored five runs, and set a team record with 15 total bases. Kris Medlen allowed three unearned runs and five hits in five innings of work and was credited with the win, while Danny Duffy pitched four shutout innings for his first career save.

Mike Hazen was introduced as the new senior vice president and general manager of the Boston Red Sox. Hazen has spent 10 years in the organization serving in various capacities in the front office, the past three as the assistant general manager in the Ben Cherington regime. The announcement was made just over a month after Dave Dombrowski was named president of baseball operations of the organization. Dombrowski said he had a list of 30 names he considered for the GM opening upon arriving in Boston, adding that he only interviewed two of the potential candidates, Hazen and Quinton McCracken, a former 12-year big leaguer who most recently has been serving as the director of player development for the young and upcoming Houston Astros. Hazen's familiarity and track record with the Red Sox won out and gives the team continuity.
The Kansas City Royals defeated the Seattle Mariners, 10–4, becoming division champs for the first time in three decades to end the longest MLB division title drought by any team.

Rookie pitcher Henry Owens stroke out five, gave up three hits and walked one in  innings, while Blake Swihart hit a solo home run and Brock Holt scored one run. The Red Sox finished their 104th season in Fenway Park with a 43–38 record, a nine-game improvement over last season's 34–47. The previous day, first-time starter Craig Breslow and other six relievers combined on a five-hitter, 8–0 victory. The improbable three-game scoreless streak began with Rich Hill, a 35-year-old  recycled starter who threw his first shutout in almost a decade, blanking the Orioles 7–0 while striking out 10 in the process. It is the first time the Orioles franchise was shut out in three straight games by the same opponent since the St. Louis Browns lost consecutive 1–0 games to the Chicago White Sox in April 1909. For Boston, this is the first sweep of a three-game set without allowing a run since September 19–21, 1958, against the Washington Senators.
September 28 – Jerry Dipoto was introduced as the Seattle Mariners new general manager and executive president of the team. He will replace dismissed GM Jack Zduriencik. Dipoto, 47, enjoyed an eight-year major league career as a relief pitcher for the Cleveland Indians, New York Mets and Colorado Rockies. He then joined the Boston Red Sox as a scout in 2003 and later earned the position of scouting director with the Colorado Rockies and the Arizona Diamondbacks, serving as interim GM in Arizona following the dismissal of Josh Byrnes. Before the 2012 season, Dipoto was named GM of the Angeles Angels and served in that capacity until this summer, when he resigned abruptly following clashes with manager Mike Scioscia, who reportedly took umbrage to Dipoto's attempts to provide him with analytical data for the purposes of aiding his in-game decision-making. The dispute escalated to the point where Dipoto walked away from the organization. His most significant transactions for the Angels included the signing of free agents Albert Pujols, Josh Hamilton, C. J. Wilson and Joe Smith, as well as making trades for Huston Street, Zack Greinke, David Freese, Chris Iannetta, Hector Santiago, Tyler Skaggs and Andrew Heaney. After a brief stop as a senior adviser with the Red Sox, he received the opportunity to join the Seattle organization. Mariners CEO Howard Lincoln said that Dipoto will be given what he needs to create the roster he wants, whether it is through developing the farm system or through trades and free agency. With the Toronto Blue Jays making the postseason, no team in baseball has been out of the playoffs longer than the Mariners. Their last postseason appearance was in 2001.

The Washington Nationals dismissed manager Matt Williams and his entire coaching staff. Nationals general manager Mike Rizzo gave the news during a meeting at Nationals Park. Williams, 49, had limited managerial experience when he was hired before the 2014 season, but he led the Nationals to a 96–66 record for the best record in the National League and an East Division in his first season. The Nationals lost to the San Francisco Giants in the Division Series and Williams was named NL Manager of the Year. Nevertheless, the Nationals went 83-79 this year, which resulted in a disappointing second-place finish after Washington entered the season with high expectations. Williams had to deal with a long list of injuries, including to half of the everyday lineup for long stretches, which was available for only two games all season. Overall, Washington went 179–145 with Williams during his two seasons tenure. The Nationals were a huge favorite to win the World Series during spring training, especially after they signed free-agent pitcher Max Scherzer in the offseason. But Williams' job appeared to be in jeopardy after the Nationals were swept in a three-game series against the New York Mets during the second week of September, losses that put Washington seven games behind first place and eventual champion Mets. According to a source, Rizzo was apologetic when he gave Williams the news about his dismissal.Nats dismiss manager Williams, coaching staff. Espn.com. Retrieved on October 5, 2015.

The Los Angeles Angels of Anaheim hired Billy Eppler as their general manager and signed him to a four-year contract, a deal that could extend his tenure in Anaheim beyond that of team's manager Mike Scioscia. Eppler, 40, worked as a New York Yankees assistant general manager and was a finalist for the Angels job when the team hired Jerry Dipoto after the 2011 season. Eppler was also a finalist for the Seattle Mariners GM job that went to Dipoto last week. Scioscia's 10-year contract expires after the 2018 season, while Eppler's contract extends through the 2019 season. Neither of the two previous general managers hired by Angels' owner Arte Moreno, Tony Reagins and Dipoto, had a contract that outlasted Scioscia's. Reagins served the Angels from 2007 until his 2011 resignation, while Dipoto resigned on July 1 amid renewed friction with Scioscia.

Conversely, the Pirates dropped a second consecutive home Wild Card Game. Last season, Pittsburgh lost that game, 8–0, to the eventual World Series Champion San Francisco Giants behind a pitching gem from Madison Bumgarner and a grand slam by Brandon Crawford. To complete his feat, Arrieta tossed the first complete-game shutout for the Cubs in the postseason since Claude Passeau threw a one-hitter in the 1945 World Series against the Detroit Tigers.

Dexter Fowler, Starlin Castro and Soler each had two of Chicago's six hits in a game played in front of a lively crowd of 47,859, a postseason record at 10-year-old Busch Stadium, that included thousands of Cubs fans. The Cardinals homered three times, including a leadoff shot by Matt Carpenter and consecutive shots by Kolten Wong and Randal Grichuk with two outs in the fifth inning, which chased Cubs starter Kyle Hendricks one out shy of qualifying for the victory in his postseason debut. Travis Wood, Trevor Cahill and Héctor Rondón combined for  scoreless innings of relief, with Wood getting the win and Rondón a save.
The Los Angeles Dodgers tied their best-of-five NLDS against the visiting New York Mets with a 5–2 comeback win after a four-run rally in the seventh inning, keyed by a controversial and hard slide from Chase Utley that sent Mets shortstop Rubén Tejada to the hospital with a fractured right fibula. Adrián González hit a two-run double with the game 2–1, two outs and runners at the corners, highlighting the rally after Howie Kendrick's fielder's-choice grounder that resulted in the tying run scoring on an overturned call after Utley's slide upended Tejada. González scored the fourth run of the inning on a double by Justin Turner. Zack Greinke allowed two runs and five hits in seven innings, striking out eight and walking none to take the win. Chris Hatcher pitched a perfect eight inning and Kenley Jansen closed the ninth for the save, completing a five-hitter.

Dallas Keuchel remained undefeated at Minute Maid Park with a sterling pitching performance, and Chris Carter went 3-for-3 with a double and one home run, leading the Houston Astros to a 4–2 win over the Kansas City Royals for a 2–1 lead in the best-of-five ALDS. Keuchel improved to 16–0 at home with a 1.45 ERA by allowing one run on five hits and three walks with seven strikeouts, throwing a season-high 124 pitches and going deep in each of his final two innings. Lorenzo Cain hit a solo homer for the Royals leading off the fourth inning. After that, Keuchel pitched out of a jam in which the Royals had two base runners in the fifth, and retired Alex Gordon with a runner on third base in the sixth inning. Then Carlos Gómez singled in the bottom of the sixth to score George Springer and make it a 3–1 game. In the seventh, with one runner on second and Cain representing the tying run, Keuchel struck out him to preserve the lead and cap his outing. As for Carter, who finished a triple shy of the cycle, he hit a double in the fifth inning and subsequently scored the go-ahead run on an RBI single by Jason Castro. He then belted a first-pitch leadoff homer in the seventh off reliever Danny Duffy, bringing the score to 4–1. Kansas City starter Edinson Vólquez fell to 0–3 in his postseason career by allowing five hits and three runs in  innings. Reliever Tony Sipp earned the hold with  innings of work, and Luke Gregerson gave up a leadoff homer to Gordon in the ninth, before finishing off the Astros' first playoff game in Houston in 10 years with a four-out save.
Troy Tulowitzki drove in four runs, including three with a home run for his first hit in the ALDS, and Marco Estrada held the Texas Rangers to five hits and one run in  innings, as the Toronto Blue Jays cut their deficit to 2–1 in the best-of-five series with a 5–1 victory at Globe Life Park. Estrada, who made his first postseason start and third postseason appearance, used his fastball-changeup combination and did not walk a batter, striking out four while throwing 57 of his 89 pitches for strikes. Toronto started the sixth inning with consecutive singles to chase Rangers starter Martín Pérez, and Edwin Encarnación then drew a 10-pitch walk from reliever Chi Chi Gonzalez to load the bases before the Rangers' fourth double play in as many innings, twice with the bases loaded, that prevented any runs from scoring. Tulowitzki, by then 0-for-11 in the series, followed with his homer against González on a full-count changeup. Previously, Tulowitzki have walked with the bases loaded in the fourth inning. The first Blue Jays run came on a double play grounder with the bases loaded and no out in the second inning. Overall, Pérez gave up four runs on six hits and three walks in five plus innings and was charged with the loss. The Estrada performance was backed up by four relievers who delivered  perfect innings.

The Kansas City Royals overcame a four-run deficit to stave off elimination against the Houston Astros and send the ALDS back to Kansas City for a decisive fifth game. The Royals scored five times in the eighth inning to defeat the Astros, 9–6, and even the best-of-five series at two games apiece. Kansas City began the eight inning with four consecutive singles off reliever Will Harris, and all four runners scored to tie the game. Harris then was relieved by Tony Sipp, who suffered the loss, though, after allowing a fifth consecutive single to Eric Hosmer, who drove in the first run and scored the go-ahead run to cap the five-run eighth. The Royals took advantage when Astros shortstop Carlos Correa could not handle a deflected grounder that might have been a double-play ball and committed an error. Later in the inning, Alex Gordon batted an RBI groundout that put Kansas City ahead, while Hosmer blasted a two-run homer in the ninth inning to make it 9–6. Royals starter Yordano Ventura allowed three runs with eight strikeouts in five innings, giving up solo homers to Carlos Gómez and Correa. Ventura was followed by Kelvin Herrera, who allowed one run in the sixth, and Ryan Madson, who gave up back-to-back homers to Correa and Colby Rasmus in the seventh and still got the win. Wade Davis pitched two scoreless innings for his second save. As for Rasmus, it was his third home run in the series and the fourth in five postseason games, as he homered in the Astros' AL wild-card win over the New York Yankees. Astros rookie right-hander Lance McCullers Jr. was sharp in his postseason debut, limiting the Royals to two runs on two hits and two walks with seven strikeouts over  innings. McCullers allowed a two-run homer to Salvador Pérez in the second inning to give the Royals an early lead, but retired 15 of the next 18 batters before leaving after hitting Pérez with a pitch with one out in the seventh. Besides his costly error, Correa homered twice, doubled, singled, drove in four runs and scored two times in four at-bats. At 21 years and 20 days old, he became the youngest player in American League history to record a multi-homer game in the postseason.
The Toronto Blue Jays stayed alive in the postseason by relying on the long ball and their Cy Young Award winners R. A. Dickey and David Price, beating the Texas Rangers 8–4 and even the ALDS at two games apiece, to force a deciding Game 5 at home. Josh Donaldson, Chris Colabello and Kevin Pillar each hit home runs off Rangers starter Derek Holland with Toronto's season hanging in the balance for the second consecutive game. Pillar went 3-for-4 and finished with three RBI, while Donaldson and Colabello each drove in two runs. Overall, Toronto racked up 12 hits. Dickey made his first career postseason appearance a memorable one, allowing only one run on five hits with three strikeouts and no walks, even if he did not qualify for the win. Dickey was pulled by manager John Gibbons with a 7–1 lead and two outs in the fifth inning. Price, who was the losing pitcher in the series opener, was out of the mix for an eventual start in Game 5. Price then retired the next nine outs, working into the eighth inning to pick up the victory despite allowing three runs, while Aaron Sanchez and Roberto Osuna combined on  innings of perfect relief. The Blue Jays will try to become only the third of 30 teams to win a best-of-five series after losing the first two games at home. The 2001 New York Yankees pulled off such a comeback in a division series against the Oakland Athletics, and the San Francisco Giants did it against the Cincinnati Reds in 2012.
The Chicago Cubs set a postseason mark for a club with six home runs and beat the St. Louis Cardinals, 8–6, for a 2–1 lead in the best-of-five NLDS playoffs. Cubs starter Jake Arrieta struck out nine before departing in the sixth inning, and the bullpen finished the job in the first playoff game at Wrigley Field in seven years. Kyle Schwarber and Starlin Castro hit solo home runs against Michael Wacha in the second and fourth innings, respectively. In the fifth, Kris Bryant hit a two-run homer off Wacha and Anthony Rizzo added a solo shot against reliever Kevin Siegrist. Then, Jason Heyward responded with a two-run homer in the sixth, which got to Arrieta for four runs in his worst start in four months, but the Cardinals were unable to keep the Cubs in the ballpark. In the bottom of the inning, Jorge Soler connected a two-run blast against Adam Wainwright and made it a 7–4 game. The final homer for Chicago went to Dexter Fowler, a solo shot against Jonathan Broxton in the eight inning. St. Louis trailed 8–4 before Stephen Piscotty hit a two-run shot against Héctor Rondón with two outs in the ninth, which caused alarm at Wrigley Field, but Rondón retired Matt Holliday on a groundout for the final out.
The New York Mets crushed the Los Angeles Dodgers, 13–7, in the first postseason game played at Citi Field. The Mets took an early lead in the second inning on a bases-loaded double from Curtis Granderson, erasing a three-run deficit and never looked back to set a franchise postseason run record and take a 2–1 advantage over the Dodgers in the NLDS playoffs, despite a subpar outing from Matt Harvey. Harvey labored through five innings in his postseason debut, allowing three runs (two earned) on seven hits and two walks, striking out seven while throwing a total of 97 pitches. Harvey was backed by four relievers that combined to throw four solid innings to preserve the victory. Granderson drove in five runs with two doubles, Yoenis Céspedes belted a three-run home run, and Travis d'Arnaud added a two-run shot with an RBI-single. Dodgers starter Brett Anderson took the loss, as he allowed six runs and seven hits in three ineffective innings. After that, Alex Wood was charged with four runs and Pedro Báez was tagged with three more without retiring a hitter. Yasmani Grandal hit a single to drove in the first two runs for Los Angeles, while Adrián González homered and Howie Kendrick slugged a three-run shot.
A total of 21 home runs were batted in the four Division Series played on this date, blowing away the single-day postseason record of 15, set back on October 3, 1995, just when major league's offensive atmosphere was heightened. Moreover, the eight home runs combined by the Chicago Cubs and St. Louis Cardinals at Wrigley Field also set a record for a postseason game, while the 61 runs scored in the four games surpassed the previous high of 48 stabilized on October 2, 2002.

The Chicago Cubs clinched a postseason series at Wrigley Field for the first time ever, after beating the St. Louis Cardinals to win the NL Division Series in four games. A day after hitting a postseason-record six homers, the Cubs got home runs from Javier Báez, Anthony Rizzo and Kyle Schwarber en route to the NL Championship Series. Báez hit a three-run homer in the second inning, Rizzo belted a tiebreaking home run with two outs in the sixth, and Schwarber cleared the right field scoreboard with his 7th-inning blast to give the Cubs a 6–4 lead. The shot by Rizzo, was his second in two games against reliever Kevin Siegrist, who was charged with the loss. The Cubs fell behind quickly on Stephen Piscotty's two-run homer in the first off starter Jason Hammel, who left after giving up two runs over three innings. Seven relievers combined to hold the Cardinals to two runs and five hits the rest of the way. Trevor Cahill earned the win, and Héctor Rondón closed the nine for the save. Following an MLB-best 100–62 record in the regular season, the Cardinals failed to advance in the postseason after winning at least one series the previous four years. Pitching on three days rest, St. Louis starter John Lackey gave up four runs and four hits over three innings after out-pitching Jon Lester, 7–0, in the series opener. The Cubs last reached the NLCS in 2003, when they lost in seven games to the Florida Marlins, the eventual 2003 World Series winners.

Clayton Kershaw finally came through the postseason, holding the New York Mets to just one run on three hits over seven innings, and leading the Los Angeles Dodgers to a 3–1 win at Citi Field. The victory leveled their NLDS at 2-2 and forced a decisive Game 5 at Los Angeles on October 15. As a result, the reigning National League MVP and three-time Cy Young Award winner snapped a five-start losing streak in the playoffs, the longest in Dodgers franchise history. Pitching on three days rest, following his Game 1 loss, Kershaw struck out eight and walked only one through 94 pitches, yielding his only run on a fourth-inning home run by Daniel Murphy. The Dodgers scored their runs in the third inning in a rally started by an-out single from Kershaw and keyed by an RBI-single by Adrián González, followed by a two-run double by former Met Justin Turner off New York rookie starter Steven Matz. The 24-year-old Matz pitched five-plus innings, allowing the three runs on six hits and two walks while striking out four batters. Matz went 4–0 with a 2.27 ERA in six major league starts in the regular season, and was pitching in a big league game for the first time in 19 days, after an ailing back sidelined him late in September. Still, he looked effective through 85 pitches, 50 of them for strikes. Kenley Jansen got four outs for his second save in the series. With two runners on base in the eighth and a 3-2 count, he retired Murphy on a fly out to right field. Jensen then worked a 1-2-3 ninth as the Dodgers ended a seven-game losing streak in road playoff games.

The Toronto Blue Jays channeled their frustration into a four-run burst and a trip to the American League Championship with a 6–3 win over the Texas Rangers at Rogers Centre. With the best-of-five ALDS level at 2-2, a tense game turned during a stormy 53-minute seventh inning, which had managers and umpires checking the rule book, featured two dugout clearing confrontations, a full-capacity crowd showering the field with debris, two ejections, and Toronto playing the game under protest. Overcoming one of the most unusual plays in playoff history, José Bautista blasted a tiebreaking three-run home run off reliever Sam Dyson that would define this series. In the first inning, Prince Fielder hit an RBI grounder off Toronto starter Marcus Stroman to put ahead Texas 1–0. Shin-Soo Choo extended the margin to 2–0 with a solo shot to right field in the third. In the bottom of the inning, Bautista hit a double against Cole Hamels that drove in Ben Revere with the first Blue Jays run. Edwin Encarnación then pulled his team even with Texas, 2–2, with a solo blast off Hammels in the sixth, but the Rangers reclaimed a 3–2 lead on a controversial play that started the seventh inning on a weird path that would define the series. Rougned Odor led off the seventh with a single and went to third on a sacrifice and groundout. Odor scored when catcher Russell Martin's throw back to Sanchez on a 2-2 deflected off batter Choo and dribbled toward third base and allowed the tiebreaking to score. Home plate umpire Dale Scott initially ruled it a dead ball, but after Rangers manager Jeff Banister questioned the call, the umpires huddled and Odor was sent home. Martin was given an error. Blue Jays manager John Gibbons argued and fans littered the field as they booed while Gibbons asked for a video review. The call stood, and the Blue Jays announced that they were playing the game under protest. Texas committed three errors to start the Blue Jays' seventh. After a forced out at home, Dyson replaced Hamels to face Josh Donaldson, whose flare to second base eluded Odor, who got the force at second as the tying run scored. Bautista then hit his two-out, mammoth homer to left field to give the Blue Jays a definitive 6–3 lead. Hamels allowed five runs (two earned) on four hits and two walks while striking out eight in  innings to take the loss. Reliever Aaron Sanchez pitched  innings and was credited with the win, while Roberto Osuna struck out four in  innings and earned the save. The Toronto Blue Jays became one of only three teams to come back and win a best-of-five series after losing their first two games at home. The New York Yankees pulled off such a comeback in a division series against the Oakland Athletics in 2001, and the San Francisco Giants did it against the Cincinnati Reds in 2012 and won the World Series. The Blue Jays will now attempt to be in their first World Series in 22 years. They will first have to face the Kansas City Royals or Houston Astros in the best-of-seven ALCS.
Johnny Cueto hurled a masterpiece in the fifth and decisive game of the AL Division Series, holding the Houston Astros to two hits over eight innings, as the Kansas City Royals rallied once more for a 7–2 victory that sent them to the AL Championship Series for a second year in a row. Cueto, who was acquired in a July transaction with the Cincinnati Reds, retired the final 19 batters he faced after Luis Valbuena hit a two-run home run. in the second inning. It was the only mistake Cueto made. The right-hander walked none and struck out eight, his high in 15 starts with the Royals, including two appearances in the ALDS. With the Royals trailing by two runs in the fourth inning, Lorenzo Cain hit a single against Astros starter Collin McHugh before Eric Hosmer fought off a pitch and blooped a single to center field. Cain was running on the pitch from first base and kept running when center fielder Carlos Gómez fell down after fielding the ball, which allowed Cain to circle the bases and score. Alex Ríos then provided the key hit, a two-run double off reliever Mike Fiers in the fifth, and later scored on a Ben Zobrist sacrifice fly that gave Kansas City a 4–2 lead. Kendrys Morales capped the game with a three-run homer off Dallas Keuchel in the eighth to put it away. McHugh, who won the ALDS opener for Houston, allowed three runs in four-plus innings and charged with the loss. Wade Davis needed just eight pitches to retire the three batters he faced in the ninth. Kansas City will receive the Toronto Blue Jays at Kauffman Stadium in the ALCS opener on October 16.
October 15 – Daniel Murphy provided most of the offense that allowed the New York Mets to edge the Los Angeles Dodgers, 3–2, to win the decisive  Game 5 of the NLDS at Dodger Stadium. Mets starter Jacob deGrom struggled early in the game but regrouped and finished in a strong way. The Mets advanced to their first NLCS since 2006, as they did so by beating Clayton Kershaw and Zach Greinke, two of the top pitchers in major league, in the first and final games of the best-of-five series. The Mets jumped in front 1–0 in the first inning of decisive game, when Murphy hit a one-out RBI-double against Greinke. Four consecutive singles in the bottom of the inning off deGrom allowed the Dodgers to rally, with Justin Turner and Andre Ethier driving in one run apiece for a 2–1 Los Angeles lead. Murphy then opened the fourth inning with a single to right field. After one out, the Dodgers shifted three infielders to the right side and left no one near third base when left-handed hitter Lucas Duda came to bat. After Duda walked on a 3-1 pitch count, Murphy jogged to second and suddenly sprinted and stole third base unopposed against an infield shift, and scored the tying run on a Travis d'Arnaud sacrifice fly. Two innings later, Murphy smashed a go-ahead home run off Greinke that led the Mets over the Dodgers, 3–2. deGrom earned his second victory of the series, allowing two runs on six hits and three walks, while striking out seven in six innings of work. Noah Syndergaard pitched a scoreless inning of relief and Jeurys Familia was perfect in two innings and earned the save. Murphy, who went 7-for-21 (.333) in the five games, scored seven runs with five RBI and homered three times off Kershaw (2) and Greinke (1). As for Greinke, he allowed three runs on six hits and one walk and struck out nine in  innings, being credited with the loss. The Mets will face the Chicago Cubs in the NLCS beginning on October 17 at Citi Field stadium. The Mets will try to advance to their first World Series since 1986, while the Cubs try to do it for the first time since 1945.

Alcides Escobar and Lorenzo Cain also drove in runs off Estrada, who was charged with the loss. Then Eric Hosmer and Kendrys Morales added one RBI-run apiece off reliever LaTroy Hawkins to put the game away. Vólquez allowed two hits and stroke five with four walks in six innings, and was credited with the win. The Royals' bullpen finished off the club's eighth consecutive ALCS victory, dating back to the 2014 season.
October 17 :
The Kansas City Royals rallied for five runs in the bottom of the seventh off Toronto Blue Jays left-hander David Price, erasing a three-run deficit and paving the way for a 6–3 victory at Kauffman Stadium in Game 2 of the American League Championship Series. Price had dominated the Royals until the seventh, retiring 18 batters in a row and allowing just a first-pitch single by Alcides Escobar to lead off the bottom of the first inning. But Kansas City erupted with five hits in the seventh, including a game-tying RBI single by Mike Moustakas and a go-ahead RBI double by Alex Gordon. Royals starter Yordano Ventura was solid through five innings, but he ran into trouble in the sixth, leaving the game with the bases loaded and one out, while trailing 3–0. Then reliever Luke Hochevar got two quick outs to keep Kansas City close. The Blue Jays were held scoreless through the first 11 innings of the series, but they finally broke out of their slump in the third, when Kevin Pillar and Ryan Goins batted consecutives doubles starting the inning. Edwin Encarnación and Troy Tulowitzki added RBI singles the sixth, and the way Price was dominating the Royals lineup, a 3–0 lead looked to be enough. After the Escobar's lead-off single, Price threw first-pitch strikes to 12 of 14 batters at one point and struck out the side in the sixth inning, giving no indication he was about to implode. Finally, Price was charged with five runs and six hits in  innings and got the loss. The Royals tacked on another run off the Toronto relief corps in the eighth, but it was unnecessary. Danny Duffy pitched a perfect seventh inning and was credited with the win, while Kelvin Herrera and Wade Davis finished off the Blue Jays with a scoreless inning apiece, with Davis earning the save.
Matt Harvey delivered  innings of four-hit, nine-strikeout ball, as the New York Mets surpassed the Chicago Cubs at Citi Field, 4–2, in Game 1 of the National League Championship Series. There were the four perfect innings with which Harvey started his work, commanding all four unhittable pitches, and striking out six of the 12 Cubs he faced, setting himself up to get deep in this game by averaging only 11 pitches an inning. Starlin Castro RBI-double ended Harvey's no-hitter bid and shutout in the fifth inning, even though a monster 463-foot eighth-inning home run by Kyle Schwarber ended his evening after 97 pitches, 64 of them for strikeouts. Mets second baseman Daniel Murphy opened the scoring with a two-out, first-inning solo homer against Cubs starter Jon Lester. After that, Curtis Granderson drove in two runs for New York with one single and a sacrifice fly, and Travis d'Arnaud hit a solo homer off the giant Mets apple in straightaway center field. Jeurys Familia followed Harvey with  innings of shutout relief for his third postseason save. Lester lasted  innings and was charged with loss, allowing four runs on eight hits and one walk, while striking out five batters. Murphy homered in his third consecutive postseason game, matching the franchise record set by Donn Clendenon in 1969. Murphy also matched a franchise single-postseason record with four home runs, set by Rusty Staub in 1973 and equaled by Mike Piazza in 2000 and Carlos Delgado in 2006.
October 18 – The New York Mets used a combination of pitching and power to defeat Jake Arrieta and the Chicago Cubs, 4–1, and took a 2–0 lead in the best-of-seven National League Championship Series. Daniel Murphy smashed a two-run home run to cap a three-run first inning off Arrieta, and that was all the Mets and their starter Noah Syndergaard needed on a cold, windy night at Citi Field, where an enthusiastic crowd was dressed in winter jackets and most of the players used balaclavas to keep their heads warm. There was a time when Syndergaard touched 99 mph with his blazing fastball, keeping the Cubs hitters off balance with curveballs and changeups to strike out nine, while allowing one run on three hits and one walk in  innings to get the win. Curtis Granderson led off the first inning with a single and David Wright followed with an RBI-double before the Murphy homer. The Mets added an insurance run in the third, when Granderson walked, stole second and third bases, to score on an RBI-single by Yoenis Céspedes. To complete his stellar night, Granderson robbed Chris Coghlan of a likely home run with a leaping grab at the centerfield wall in the second inning. The only run for Chicago came in the sixth, when Dexter Fowler singled, advanced to second on wild pitch by Syndergaard, and scored on a double off the bat of Kris Bryant. Four Mets relievers combined to pitch  scoreless innings, with Jeurys Familia earning the save. Arrieta, who posted a 22–6 record with a 1.77 ERA and also hurled a no-hitter in the season, had his second consecutive subpar outing in the playoffs. He struck out eight across five innings and allowed four runs on four hits and two walks.
October 19 – The Toronto Blue Jays bats came to life at Rogers Centre to beat the Kansas City Royals, 11–8, in Game 3 of the American League Championship Series. The Blue Jays opened the ALCS at Kansas City in frustrating form by getting shut out in Game 1 and blowing a 3–0 lead in the seventh inning of Game 2, but they returned to form when they came back to the stadium where they have won so often this year – a 53–28 record in the regular season. Toronto starter Marcus Stroman allowed four runs on 11 hits and one walk, and struck out only one batter in  innings. Even so, he was credited with the win. Kansas City took an early lead in the first inning, when lead-off hitter Alcides Escobar connected a triple and scored on a Ben Zobrist RBI-grounder. But Toronto answered in the second against Royals' Johnny Cueto, when Ryan Goins drove in two runs with a single and later scored on an RBI-single by Josh Donaldson that made a 3–1 game. In the third inning, Zobrist scored on a grounder by Eric Hosmer to cut the lead to one run. But Toronto crushed Cueto in the bottom of the inning, scoring six runs on a three-run homer by Troy Tulowitzki, a bases loaded walk by Russell Martin and an RBI-double by Kevin Pillar, which prompted Royals manager A. J. Hinch to summon reliever Kris Medlen. Donaldson connected a homer for a 9–2 lead after Medlen retired two batters. Then in the fifth inning, Escobar scored on wild pitch by Stroman and Mike Moustakas singled Zobrist to put the score 9–4, but Goins homered off Medlen in the bottom, and Toronto matched its postseason best with three homers in a game. Previously, the Blue Jays also hit three against the Texas Rangers in Game 4 of the ALDS. Toronto scored its last run in the eight on an RBI-single by José Bautista. Nevertheless, the resilient Royals tried to come back this time too, when Kendrys Morales capped a four-run surge with a two-run homer in the ninth before Roberto Osuna closed out the 11–8 victory.

At Rogers Centre, the Kansas City Royals overwhelmed the Toronto Blue Jays in Game 4 of the American League Championship Series, 14–2, and are one victory from returning to the World Series for a second year in a row. Alcides Escobar, who sparked the offense with a leadoff single off R. A. Dickey in the first inning, finished with four RBI. In addition, Ben Zobrist belted a two-run homer and Alex Ríos went 3-for-3 with a solo shot, while Lorenzo Cain drove in three runs in a 15-hit attack against six Toronto pitchers. Former Cy Young Award winner Dickey gave up five runs in  innings that left Toronto in a 5–0 hole they could not overcome,  despite scoring two runs in the third inning, and Liam Hendriks providing  innings of spotless relief to hold the Royals scoreless and to just one hit. But the Royals ended any chance of a rally roughing up LaTroy Hawkins, who came on in the seventh but did not retire a batter and allowed three runs on two hits and one walk. Ryan Tepera came to rescue him, but gave up four runs and five hits in  innings. Mark Lowe then replaced Tepera and allowed two runs in one inning. In a final act of desperation to save his relief corp for what a do-or-die Game Five, Blue Jays manager John Gibbons used utility infielder Cliff Pennington to get the final out, which he finally managed, but not before Kansas City pushed across two more runs that were charged to Lowe and completed the rout. Pennington, who allowed two hits and got one out, became the first primarily position player to pitch in major league postseason history. In contrast, the Kansas City bullpen marked the difference. Chris Young, who had not started a game since October 2, allowed two runs in  innings of work. Then Luke Hochevar, Ryan Madson, Kelvin Herrera and Franklin Morales delivered  scoreless innings, with Hochevar earning the win. Not only did four relievers to pitch  scoreless innings, but the offense supplied nine insurance runs after Young left the game to take a 3–1 lead in the best-of-seven series.
The New York Mets defeated the Chicago Cubs 5–2 in Game 3 of the National League Championship Series at Wrigley Field. David Wright and Yoenis Céspedes collected three hits apiece, Daniel Murphy homered for the fifth straight postseason game, and Jacob deGrom pitched through seven effective innings. The Mets broke a 2–2 tie on a wild-pitch strikeout in the sixth inning, as they moved to within one victory of their first trip to the World Series since the 2000 season. Céspedes hit a two-out double against Cubs starter Kyle Hendricks that brought Wright with the first run for New York in the first inning. Murphy then improved his remarkable postseason in the third, hitting his fifth homer in a row off Hendricks, to match Carlos Beltrán's MLB record for consecutive postseason games with a home run. DeGrom, who struggled in the bottom of the first inning, gave up a one-out home run to Kyle Schwarber and two singles in a total of 30 pitches. But he bounced back to retire 18 of the final 20 batters he faced. DeGrom then allowed only one hit in that stretch, on a 3-1 fastball up that Jorge Soler smacked for a solo homer that tied the game at 2–2 in the fourth. After that deGrom retired 11 batters in order, finishing with seven strikeouts and a walk. As for Hendricks, he lasted four innings before manager Joe Maddon went to his bullpen and, starting in the sixth, the Mets took advantage of some breaks. With two outs, and Céspedes running on third base, Trevor Cahill threw a knuckle curveball that Michael Conforto swung through the third strike, but the ball hit the dirt and spun away from the glove of catcher Miguel Montero, allowing Céspedes to score for a 3–2 Mets advantage. New York scored two more runs in the seventh on a single by Céspedes and a grounded out by Lucas Duda, which enabled to score Wright and Murphy, respectively. Tyler Clippard relieved deGrom in the eight and Jeurys Familia got the save with a perfect ninth inning.
October 21 :
The Toronto Blue Jays received a pitching masterpiece from Marco Estrada, to keep their season alive with a 7–1 victory over the Kansas City Royals at Rogers Centre. Estrada allowed three hits and one run in  innings of work and faced the minimum 18 batters through six innings, as Toronto pulled to within 3–2 in the best-of-seven American League Championship Series. Estrada allowed a single to Alcides Escobar in the fourth inning and did not allow another hit until Salvador Pérez homered and Alex Gordon singled with two outs in the eighth inning. Chris Colabello gave Toronto the early lead with a second inning solo home run against Edinson Vólquez. Edwin Encarnación then walked with the bases loaded in the sixth and Vólquez was relieved by Kelvin Herrera, who struck out Colabello for the first out of the inning. But Troy Tulowitzki broke the game open in when he lined a three-run double off Herrera to give the Blue Jays a 5–0 lead. José Bautista and Kevin Pillar followed with RBI-doubles of their own in the seventh and eight innings to put the game away. The series will head back to Kansas City for Game 6 on October 23.
The New York Mets reached the World Series for the first time in 15 years, following a four-game sweep of the Chicago Cubs in Game 4 of the National League Championship Series at Wrigley Field, with an 8–3 victory before 42,227 spectators. Mets first baseman Lucas Duda provided a strong offensive effort, hitting a two-out, three-run home run to center field in the first inning to lift the Mets to an early lead. Then Travis d'Arnaud followed suit, driving a solo shot to right field to make it 4–0. Duda would follow up his game-breaker with a two-RBI double in the second as the Mets order batted around Jason Hammel to gain a 6–0 advantage. Duda, who also doubled in the ninth, was hitting .125 with no extra-base hits and 13 strikeouts in 24 at-bats before the game. Additionally, Daniel Murphy connected a two-run against Fernando Rodney in the eighth inning. It was  his seventh homer of the playoffs, as the string includes a shot in the deciding Game 5 of the National League Division Series at Dodger Stadium on October 15. Murphy, who was tied with Carlos Beltrán for the postseason homer streak, also became the first player to hit a homer in six consecutive postseason games. He finished with four hits and batted .529 (9-for-17) in the series, earning NLCS Most Valuable Player honors. Bartolo Colón replaced rookie Steven Matz with two out in the fifth and runners on first and second, and struck out Kris Bryant swinging on a 3-2 pitch, preserving the Mets 6–1 lead. Colón got the win for his  inning effort, and three relievers finished the job. The Mets, who clinched their fifth NL pennant, also did it in 1969, 1973, 1986 and 2000, winning the World Series in 1969 and 1986. New York will face the winner of the Kansas City Royals–Toronto Blue Jays American League Championship Series beginning on October 27 at AL Champion ballpark.
October 22 – Don Mattingly will not return as the Los Angeles Dodgers manager in 2016. Mattingly had one more year left in his contract but he and the Dodgers came to a mutual agreement. According to a teleconference with reporters, Mattingly offered no explanation for the mutual parting. "I'm doing what's best for myself; I'm doing what's best for the organization; I just look at it that it's the right time for both parties", he said.
October 23 – The Kansas City Royals beat the visiting Toronto Blue Jays, 4–3, to earn their second straight trip to the World Series. The victory in Game 6 of the American League Championship Series sent the Royals into the World Series, starting on October 27 at Kauffman Stadium against the National League champion New York Mets. Lorenzo Cain scored from first base on a single by Eric Hosmer in the bottom of the eighth inning following a 45-minute rain delay, and it proved to be the winning run in an unexpected and exciting way. As for reliever Wade Davis, he performed a great escape in the ninth inning to seal the victory. In a historic feat, José Bautista hit a pair of home runs, including a game-tying two-run shot in the eighth inning, to become the first player in Blue Jays history with a multi-homer effort in a postseason game. Bautista also set the franchise single-postseason record by hitting four homers overall, but there would be no jubilant celebration afterward with the Royals overcoming the two blasts. Early solo home runs by Ben Zobrist and Mike Moustakas against David Price in the first two innings had staked Kansas City to a 2–0 lead, which Bautista cut in half with a solo homer off Yordano Ventura in the fourth. After that, Ventura gave up a one-out double to Edwin Encarnación in the sixth and was relieved by Kelvin Herrera, who retired the next five batters he faced. Alex Ríos then drove in an insurance run with a single in the seventh to increase the Royals lead to 3–1. Holding a two-run lead heading into the eighth, reliever Ryan Madson allowed a leadoff single to Ben Revere and struck out Josh Donaldson before yielding the two-run homer to Bautista. After a walk to Encarnación, Royals manager Yost pulled Madson and sent in Davis, who promptly retired the next two batters. In the bottom of the eight, Roberto Osuna was summoned by manager John Gibbons to get the heart of Kansas City's lineup. At this point the rain intervened and Davis had to wait in the clubhouse along with his teammates. After the delay, Cain promptly worked a leadoff walk from Osuna and Hosmer followed with a clean single that Bautista fielded down the right-field line. Rather than hit the cutoff man, Bautista threw to shortstop Troy Tulowitzki at second to keep Hosmer to a single, which gave the speedy Cain running full speed the entire way and slid into the plate easily ahead of Tulowitzki's throw for the game-winning run. When play resumed, not only did Hosmer had his RBI, because Davis returned after not pitching for over an hour. Davis then suddenly was wedged in an extremely tight spot when Toronto put runners on second and third bases with nobody out in the top of the ninth. But Davis responded, striking out the next two batters before retiring Donaldson on a ground ball to finish the game. Alcides Escobar earned ALCS Most Valuable Player honors after hitting .478 (11-for-23) with five RBI and six runs scored. The Royals-Mets will be the first MLB World Series ever played between two expansion teams.
October 26 :
The Boston Red Sox announced that former Philadelphia Phillies general manager Rubén Amaro Jr. has been hired as the club's new first base coach. Amaro will also serve as Boston's outfield instructor and assist in coaching the club on baserunning. Amaro, who also had experience as an infielder/outfielder in the majors but has never coached on any level, has expressed an interest in managing a team in the future and his focus for the time being was on coaching. Amaro replaces Arnie Beyeler, who served as first-base coach for Boston the last three seasons. The move by a GM back onto the field is not without precedent, which was the case for the Miami Marlins this past season, when GM Dan Jennings was asked by team's owner Jeffrey Loria to take over after Mike Redmond was dismissed as manager. Amaro  is signed with the Red Sox through the 2017 season.
Scott Servais was introduced as the new manager of the Seattle Mariners. Servais, who replaces departed Lloyd McClendon, will be the 17th full-time manager in Mariners history. Seattle's general manager Jerry DiPoto selected Servais from a group of six that included Charlie Montoyo, Phil Nevin, Dave Roberts, Jason Varitek and Tim Bogar, who will be on Servais' staff as Seattle's bench coach. Along with Bogar, Servais announced that Mel Stottlemyre Jr. will be his pitching coach. The other members of the staff are hitting coach Edgar Martínez and first base coach Chris Woodward, who will be retained from the previous staff. Servais, who is a former major league catcher with no prior managerial experience, served as assistant general manager for DiPoto with the Los Angeles Angels, where he oversaw scouting and player development.
October 27 – The Kansas City Royals outlasted the New York Mets in a 14-inning, five-hour, nine-minute marathon, to win Game One of the World Series by a score of 5–4 at Kauffman Stadium. Alcides Escobar connected a leadoff, first pitch inside-the-park home run; Eric Hosmer hit a game-winning sacrifice fly, and Chris Young, who was scheduled to open Game Four, pitched three hitless innings of relief along with four strikeouts. The Royals sent the game to extra innings when, trailing 4–3 with one out in the bottom of the ninth, Alex Gordon drilled a dramatic home run to deep center field against Mets closer Jeurys Familia to tie it 4–4. It was a rare blown save opportunity by Familia, who matched a franchise record with 43 regular-season saves. Then he had logged  scoreless innings through two rounds of the postseason, including a six-out save against the Los Angeles Dodgers in decisive Game 5 of the National League Division Series. Hosmer, whose critical error in the eighth briefly gave the Mets the lead, redeemed himself with his sacrifice fly to right field off reliever Bartolo Colón to score Escobar, that set off a celebration for the Kansas City players and their devoted fans. It was a tumultuous contest filled with twists and turns before the first pitch. There was a note of sadness as word spread that the father of Kansas City's starting pitcher, Edinson Vólquez, had died back home in the Dominican Republic. Then the Fox Sports broadcast of the game was interrupted during 23 minutes in the middle of the fourth inning due to technical difficulties, with the MLB International crew eventually taking over for the Fox broadcasters, while allowing play to resume. The Mets were jolted in the first by the first pitch thrown by their Game One starter Matt Harvey, when Escobar drove a fly deep to left-center. Center fielder Yoenis Céspedes briefly took his eye off the ball to glance at left fielder Michael Conforto, but the ball descended past Céspedes' glove and struck him on the lower leg, kicking towards the left-field corner, as Escobar dashed around the bases for the first inside-the-park homer in the World Series since Mule Haas of the Philadelphia Athletics circled the bases in 1929. It also was the first in a World Series Game One since Casey Stengel of the New York Giants in 1923. After that, the Mets tied the game in the fourth inning with an RBI-single by Travis d'Arnaud, then took the lead on a Curtis Granderson solo home run in the fifth, and made it 3–1, in the sixth, on a sacrifice fly by Conforto. Harvey had retired eleven Kansas City hitters in a row heading to the bottom of the sixth, but that streak ended when the Royals rallied with two runs to tie the score, as Hosmer's first sacrifice fly scored Ben Zobrist, and Mike Moustakas's single scored Lorenzo Cain with the tying run. But Hosmer, a two-time Gold Glove first baseman, committed an error in the top of the eight inning that allowed the Mets to take a 4–3 lead and made him the potential scapegoat of the game, until Gordon rescued the Royals from the dead with his solo homer off Familia, then Hosmer got his redemption in extra innings. A total of 36 players were used in the game, including 13 pitchers. Besides, Kansas City outfielder Paulo Orlando became the first Brazilian-born player to appear in a World Series game. As the game wore on, the managers turned to veterans Colón (42) and Young (36). They matched zeros for two innings before the unexpected outcome of the 14th inning.
October 28 – Johnny Cueto hurled a complete-game two-hitter, and the Kansas City Royals jumped on Jacob deGrom with a four-run fifth-inning rally, on the way to a 7–1 victory over the New York Mets and a 2–0 lead in the World Series. Cueto gave up two softly hit singles to Lucas Duda while going the distance, walking three and striking out four. The Royals scored their four runs in the fifth inning just on five singles and a walk, to take a 4–1 lead that never relinquished. The veteran Cueto faced the minimum nine batters through the first three innings, and although the Mets took a 1–0 lead in the fourth, Cueto never got rattled. After Duda's RBI single, Cueto retired 16 of the final 17 Mets batters he faced. As for deGrom, he held Kansas City to one hit through four innings but got in trouble in the fifth, when he walked Alex Gordon on a full-count slider leading off. Gordon advanced to second on a single by Alex Ríos and scored the tying run on an Alcides Escobar single. Ben Zobrist then advanced the runners to second and third with a groundout, before deGrom retired Lorenzo Cain for the second out, but Eric Hosmer responded with a tie-breaking, two-run single. Kendrys Morales then added another single, while Hosmer scored the fourth run of the inning on an RBI-single by Mike Moustakas. DeGrom, with a 3–0 record and a 1.80 ERA over 20 innings in the postseason coming in, allowed four runs on six hits and three walks while striking out two in five innings of work. Kansas City added three insurance runs in the eight, following an RBI-double by Alex Gordon, a sacrifice fly by Paulo Orlando, and an RBI-triple by Escobar. Hosmer now leads the Kansas City lineup with 15 postseason runs batted in. Earlier in the playoffs, Hosmer surpassed the franchise postseason record of 23 career RBI set by George Brett, and including the 2014 postseason, Hosmer is at 27 and counting. With his two-hit gem, Cueto became the first American League pitcher to throw a complete game in the World Series since Jack Morris did it for the Minnesota Twins in 1991. Moreover, not since Atlanta Braves' Greg Maddux in 1995 had a pitcher logged at least nine innings and allowed no more than two hits in the World Series. Additionally, Cueto allowed the fewest hits in a World Series complete game by an American League pitcher since Boston Red Sox's Jim Lonborg's one-hitter against the St. Louis Cardinals in 1967. On October 30, New York will host Kansas City in the first World Series game to be played at Citi Field ballpark. Forty-one of the 51 teams to take 2-0 leads in a best-of-seven World Series have gone on to win the title, according to the Elias Sports Bureau.
October 29 :
 The Texas Rangers announced that pitching coach Mike Maddux will not return to the next season. Maddux joined the Rangers before the 2009 season, when former team president Nolan Ryan brought him in from the Milwaukee Brewers, where Maddux was pitching coach from 2003 to 2008. Maddux had been among six coaches invited to return in 2015 and was previously offered a new contract that he had not signed. With Maddux departure, the Rangers are now searching for three new assistants, as bullpen coach Andy Hawkins resigned and hitting coach Dave Magadan left in hopes of finding a job closer to his home in Florida. Maddux is also leaving after serving four years as special assistant to general manager Jon Daniels.
The San Diego Padres hired Arizona Diamondbacks third base coach Andy Green as their new manager. Green takes over a team that underachieved despite San Diego general manager A. J. Preller hatched an aggressive offseason roster shuffle during the offseason. The Padres finished 74-88 and fourth place in the National League West Division, 18 games behind the division champion Los Angeles Dodgers. At this time, San Diego has had five straight losing seasons and has missed the playoffs for nine straight years. A former major league infielder, Green has four seasons of minor league managerial experience in spite of his young age (38). From 2011 through 2014, he managed in the D-Backs' minor league system, guiding the Missoula Osprey to a Pioneer League championship in 2012 and achieving a pair of postseason berths for the Double-A Mobile Bay Bears in 2013 and 2014, being named Southern League Manager of the Year in each of those two seasons.
The Toronto Blue Jays announced that general manager Alex Anthopoulos rejected a five-year contract extension and is leaving the team. The announcement was made the same day that he earned The Sporting News executive of the year honors. Since Anthopoulos joined the team in 2009, the Blue Jays posted a 489–483 record, including the American League East Division title with a 93–69 record, while earning their first trip to the postseason since winning the World Series in 1993. They were eliminated from the American League Championship Series by the Kansas City Royals in six games. According to a report, Anthopoulos chose to leave because of concerns over the imminent changing dynamic in Blue Jays new management. Mark Shapiro, who was the Cleveland Indians' general manager for eight years, was hired to become Toronto's president and CEO in August, and is slated to assume his duties with the team on November 2.
October 30 – The New York Mets rallied from an early deficit to beat the Kansas City Royals, 9–3, in the first World Series game ever played at Citi Field, which set a record when 44,781 fans attended the game. Noah Syndergaard settled down after yielding three runs and six hits in the first two innings, Curtis Granderson and David Wright each belted a two-run home run, as the Mets took Game 3 of the series after two tough losses in Kansas City.  Syndergaard's first pitch was a 97 mph fastball just off the inside corner and above the head of Royals leadoff hitter Alcides Escobar, who had tormented the Mets for crushing first-pitch fastballs in the series, including one for an inside-the-park home run in Game 1. Obviously, Syndergaard wanted to attack the Royals early, make them feel uncomfortable, a feat that Matt Harvey and Jacob deGrom had failed to accomplish in the first two games. Finally, Escobar struck out swinging, the first of six strikeouts for Syndergaard in the game. On a would-be inning-ending double play, Mets shortstop Wilmer Flores threw wide to first base, allowing Eric Hosmer to beat the throw and Ben Zobrist to score the game's opening run. The Royals did not attempt to retaliate after that, but there were certainly some discontented players in their clubhouse afterward. In the bottom of the inning, Granderson singled and Wright homered against Yordano Ventura which provided a 2–1 lead. But the Royals did not seem fazed. They scored two runs in the second on an RBI-single by Alex Ríos, who later scored on Travis d'Arnaud's passed ball. Then Granderson blasted another two-run homer in the third. Syndergaard had singled ahead of Granderson and he could continue to attack the Royals. After Escobar singled for the fourth hit of Kansas City the second inning, Syndergaard retired the next 12 Royals in order. Even in the sixth, when Syndergaard allowed a two-out single to Mike Moustakas and walked two consecutive batters to load the bases, he retired Ríos on a grounder to shortstop for the last out and complete his outing. Syndergaard was charged with three runs, giving up seven hits, two walks and striking out six in six innings. Michael Conforto hit an RBI-single in the fourth that put the score 5–3, as the Mets erupted for four runs in the sixth. Juan Uribe, just back from a chest injury, pinch-hit for Syndergaard and delivered an RBI single against Franklin Morales that put the Mets ahead 6–3. Then Wright added a two-run single against Kelvin Herrera and Yoenis Céspedes added a sacrifice fly. Aided by more unsteady fielding from a Royals team known for tight defense, New York collected hits from nine different players and finished with 12. Kansas City rookie Raúl A. Mondesí made history after debuting in a World Series game, becoming the first rookie to ever do so. As for Ventura, he was charged with the loss after allowing five runs on seven hits, while striking out one without walks in  innings. Lifted by the roars of the home fan base, the Mets narrowed the deficit in the best-of-seven World Series to 2–1.
October 31 – The Kansas City Royals capitalized an error by New York Mets second baseman Daniel Murphy, and rallied for three runs in the eighth inning for a 5–3 victory at Citi Field and a 3-1 World Series lead. The Royals insurgence against relievers Tyler Clippard and Jeurys Familia wasted a pair of home runs hit by Michael Conforto and a strong start from Steven Matz, to put the Mets on brink of elimination. Besides Murphy's blunder and bullpen's fault, outfielder Yoenis Céspedes struggled in every aspect of the game. Kansas City closer Wade Davis came on in the eighth inning to register a six-out save, and Salvador Pérez went 3-for-4 with a double, one RBI and one run scored. Conforto bashed his first home run of the game against Kansas City starter Chris Young to lead off the third inning, giving the Mets a 1–0 lead. Wilmer Flores followed with a single, advanced on a wild pitch and was sacrificed to third by Matz, scoring on a Curtis Granderson's sacrifice fly to make it 2–0. In the fifth inning, Pérez hit a sinking liner to center field that turned into a double when Céspedes accidentally kicked it into left field as he reached down to try to make the catch. Next, Alex Gordon slapped an RBI single for the first Kansas City run. As for Céspedes, he previously misplayed and booted a ball into an inside-the-park home run by Alcides Escobar on Matt Harvey's first pitch in Game 1, yet Cespedes offered a poor optic when he jogged after the ball to retrieve it. After this, Conforto hit his second home run of the game off reliever Danny Duffy to lead off the bottom of the inning, giving the Mets a 3–1 lead. At age 22, Conforto became the first rookie to connect two homers in a World Series game since Atlanta Braves' Andruw Jones (19) did it at Yankee Stadium in 1996. Conforto also became the first Mets player to hit two home runs in a World Series game since Gary Carter in 1986. In between, Mets hometown rookie Matz held the Royals to two runs with two hits and five strikeouts without walks in five innings-plus. Mets manager Terry Collins then sent Clippard, his fifth pitcher of the night, out to start the eighth inning. Trailing, 3–2, the Royals drew consecutive one-out walks against Clippard, prompting manager Collins to call on closer Familia to try for a five-out save. Familia forced Eric Hosmer to tap a slow roller to the right side and Murphy charged in only to have the dribbler sneak under his glove and roll into right field, which allowed Ben Zobrist to score and Lorenzo Cain to reach third. On a 1-2 count, Mike Moustakas singled in the go-ahead run past the glove of a diving Murphy and Pérez drove in another insurance run. For second time in the Series, Familia failed to rescue Clippard and blew the save. Two of the three runs the Royals scored off Familia were charged to Clippard, who was credited with the loss. Previously, the usually reliable Familia failed to rescue Clippard and blew the save, as he had allowed Gordon's ninth-inning, tying homer in a Game 1 loss. Murphy, who still made every play look easy in the National League Championship Series and led the Mets to their first World Series since 2000 with seven homers in nine playoff games, has been silenced by Royals pitching. But he hit a one-out infield single in the ninth off Davis. Céspedes followed with another single, and Lucas Duda hit an easy liner to third baseman Moustakas, but Céspedes found himself way too far off first base, giving the Royals an easy double play and another incredible comeback. Ryan Madson pitched a perfect seventh for the win, and Davis worked two scoreless innings for his first save in the Series.

November
November 1 – The Kansas City Royals captured the second World Series title in franchise history, with a 12-inning, 7–2 victory over the New York Mets in Game 5 at Citi Field. Once again, Kansas City came from behind to overcome a dominant start by Matt Harvey, who carried a 2–0 shutout through eight innings, then convinced Mets manager Terry Collins to let him remain in the game. As a result, the Royals rallied for a pair of runs in the ninth to tie it at 2–2 before the five-run explosion in the decisive 12th. Salvador Pérez, who hit .364 (8-for-22) in the Series, earned Most Valuable Player honors. Pérez also was involved in the tying run and started the five-run rally to put the game away. Edinson Vólquez returned from his father's funeral in the Dominican Republic in time to start the game for the Royals. When Vólquez was preparing to start Game 1 of the Series, his father Daniel died at age 63 and had been battling heart disease. Even though, Vólquez allowed just three runs on six hits in six innings of Kansas City's 5–4 victory in the opener. This time Vólquez gave up a leadoff home run to Curtis Granderson on his third pitch of the night. But he settled down and retired the next three batters, then faced the minimum nine batters over the next three frames thanks to a pair of double plays, holding the Mets' lead at 1–0 while Harvey dominated the Royals inning after inning. Vólquez kept his composure as the game moved to the sixth, when the Mets used a Granderson walk, a David Wright single and an error to load the bases with nobody out. But Vólquez limited the damage to one run, striking out Yoenis Céspedes and allowing a sacrifice fly RBI to Lucas Duda before retiring Travis d'Arnaud on a third base ground ball, keeping the Royals well within striking distance. Harvey took the mound for the ninth with his pitch count at 102 and the Mets leading 2–0. Up to that point, Harvey's line was four hits with nine strikeouts and one walk. Harvey proceeded to walk leadoff batter Lorenzo Cain, who subsequently stole second base and scored on an RBI double by Eric Hosmer. Mets manager Collins then summoned Jeurys Familia to close out the game, but with Hosmer at third base and one out, Pérez hit a soft ground ball to third, with the infield in, and Wright looked Hosmer back to third and threw to first for the out. But Hosmer bounced around third the whole play, waited for Wright to make the throw and he bolted for home. Duda took the throw for the second out but his relay to the plate was wide right, pulling d'Arnaud away from the play and allowing Hosmer to score the tying run. With both teams tied at 2–2, the game went into extras innings, and the Royals took control in the top of the 12th scoring five runs. Pérez started with a leadoff single off losing pitcher Addison Reed, while pinch-runner Jarrod Dyson stole second and moved to third on a grounder. Christian Colón then stepped in as a pinch-hitter for reliever Luke Hochevar. It was his first plate appearance since October 4, but he was able to hit a hard single to left field that brought home the tiebreaking run. After that, Paulo Orlando grounded into fielder's choice to second baseman Daniel Murphy, and was safe at second on a two bases error by Murphy. Alcides Escobar followed with a double that scored Colón and advanced Orlando to third. With Kansas City up 4–2, Ben Zobrist was intentionally walked and Bartolo Colón replaced Reed. Cain then hit a bases loaded double against Colón to push the score to 7–2. Hochevar was credited with the win and Wade Davis retired the last three outs of the Series. The Kansas City Royals are the first team since the 1989 Oakland Athletics to win the World Series a season after losing the World Series the previous year. They also are the first American League team since the 1961 New York Yankees to win a World Series a year after losing Game 7 of the World Series.Top stats to know: Royals win World Series. Espn.com.

November 2 – The Miami Marlins announced the hiring of Don Mattingly as their new manager. Mattingly will receive a four-year contract, becoming the eighth manager of the Marlins  since the 2010 season. Mattingly will replace Dan Jennings, who made the unusual transition from general manager to field manager earlier this year after Mike Redmond was dismissed. Mattingly posted a 446–363 record and a winning record in each of his five seasons for the Los Angeles Dodgers from 2011 to 2015, guiding his club to the National League West Division title in each of the final three years of his term, a first in franchise history.
November 3 – The Washington Nationals hire Dusty Baker as their new manager. A three-time National League Manager of the Year, Baker takes over from Matt Williams, who was dismissed in October after the regular season. The Nationals reportedly first offered the manager's job to Bud Black, but financial terms could not be agreed. Baker arrives in Washington after managing the San Francisco Giants (1993–2002), Chicago Cubs (2003–2006) and Cincinnati Reds (2008–2013), collecting a career record of 1,671–1,504 as part of his NL Pennant with San Francisco (2002) and the first divisional title in over a decade for Chicago (2003). To date, Baker is one of only three African Americans to manage a World Series team, joining Cito Gaston of the Toronto Blue Jays (1992–1993) and Ron Washington of the Texas Rangers (2010–2011).
November 4 :
The New York Mets agreed to a two-year contract extension with manager Terry Collins, as he reportedly does not want to manage too much longer but was said to be open to continuing for at least the next two seasons. The 66-year-old Collins is an oft-mentioned National League Manager of the Year candidate after leading the Mets to a surprising 90-win season, en route to their first National League pennant in 15 years and World Series run, despite to dealt with a number of injuries early in the season plus questions as to when top prospects would be promoted. Collins has been managing the Mets since 2011, though the 2015 season marked his first winning campaign.
The Washington Nationals hired recently departed Texas Rangers pitching coach Mike Maddux to fill the same role in their organization under new manager Dusty Baker. Widely considered one of the game's more respected coaches of any discipline, Maddux could become the highest-paid pitching coach in the major leagues, according to a report.
The Cincinnati Reds promoted vice-president and assistant general manager Dick Williams to the general managerial role, while previous general manager Walt Jocketty will remain with the club as its president of baseball operations for one more year before moving into an advisory role. After 21 years as a general manager with the St. Louis Cardinals and Cincinnati, Jocketty wanted a less demanding role.
November 12 :
Colby Rasmus made history when he became the first major league player ever to accept a qualifying offer. The 29-year-old Houston Astros outfielder will return to the team in 2016 on a one-year, $15.8 million contract, as Rasmus is the first big leaguer free agent to accept one qualifying offer since the system came in place three years ago. The next day, Baltimore Orioles catcher Matt Wieters agreed to accept the team's one-year offer.
The Los Angeles Angels of Anaheim agreed to acquire Gold Glove winner shortstop Andrelton Simmons from the Atlanta Braves, along with rookie catcher Jose Briceno. Pitchers Sean Newcomb and Chris Ellis are going to Atlanta in return, along with long-time Angels shortstop Erick Aybar. In addition, the Braves will pick up $2.5MM in the swap to offset some of Aybar's salary. Simmons also is under contract through 2020, whereas Aybar could become a free agent next postseason.
November 13 – Los Angeles Dodgers pitcher Brett Anderson decided to accept his qualifying offer, meaning he will get a one-year, $15.8 million deal for 2016. Anderson joins Colby Rasmus and Matt Wieters in taking the qualifying offer, the first three players to do so since the system started. In the first three years of the current iteration of Major League Baseball's free-agent system, 34 players were made qualifying offers by their former teams. All 34 declined. This year, a record 20 players were made qualifying offers, a procedural move primarily designed to protect their former team's right to a compensatory draft pick.Qualifying offers will reshape 2016 Draft .

November 14 – The Boston Red Sox announced the acquisition of four-time, All-Star closer Craig Kimbrel from the San Diego Padres in return for prospects Manuel Margot, Javier Guerra, Carlos Asuaje and Logan Allen. In dealing Margot and Guerra, the Red Sox took advantage of two of the deeper positions in their minor league system. Boston assumed $25 million remaining on Kimbrel's contract, but have him under control for up to three more seasons.
November 23 – The Los Angeles Dodgers hired Dave Roberts as their new manager. Roberts will succeed Don Mattingly, who mutually parted ways with the Dodgers last month after five years with the team. Roberts, whose father is an African-American former Marine and mother is a Japanese-American, becomes the first minority manager of the storied franchise that signed the first African-American player, Jackie Robinson. Roberts, 43, was born in Okinawa, Japan, where his father was stationed. A former Dodgers outfielder, Roberts played for the team from 2002 to 2004. He also played for the Cleveland Indians, Boston Red Sox, San Diego Padres and San Francisco Giants during a 10-year major league career that ended in 2008. Roberts is perhaps best known for his stolen base in the 2004 playoffs, which sparked a Red Sox eight-game winning streak that culminated with a World Series championship, its first in 86 years. The Dodgers announced that Roberts would officially be introduced at a news conference at Dodgers Stadium on December 1.
