## Events
### January

* January 14 – The California Angels acquire veteran pitcher Jack Fisher from the Cincinnati Reds for pitcher Bill Harrelson and minor-league infielder Daniel Loomer.
* January 15 – The Seattle Pilots (soon to be the Milwaukee Brewers) trade first baseman Don Mincher and third baseman Ron Clark to the Oakland Athletics for pitchers Lew Krausse Jr. and Ken Sanders, catcher Phil Roof and outfielder Mike Hershberger.
* January 16 – Curt Flood, Gold Glove former centerfielder of the St. Louis Cardinals, files a civil lawsuit challenging Major League Baseball's reserve clause, a suit that will have historic implications. Flood will refuse to report to the Philadelphia Phillies after he was traded by the Cardinals three months ago, contending the baseball rule violates federal antitrust laws.
* January 17:
** The Sporting News names Willie Mays as Player of the Decade for the 1960s.
** The January 1970 Major League Baseball Draft sees future stars Chris Chambliss (Cleveland Indians), Chris Speier (San Francisco Giants), Rick Burleson (Boston Red Sox), Doug DeCinces (Baltimore Orioles) and Bill Madlock (Washington Senators) drafted and signed by MLB teams.
* January 19 – The New York Mets appoint former MLB catcher and field manager Bob Scheffing as vice president and general manager, filling the void left by the January 14 death of Johnny Murphy. Scheffing, 56, previously was a senior special assignments scout for the Mets' organization.
* January 20 – Lou Boudreau is elected to the Hall of Fame by the Baseball Writers' Association of America on 232 of 300 ballots. Ralph Kiner finishes second with 167, 58 votes short.
* January 29 – Pitcher Miguel Fuentes, who threw the last pitch for the Seattle Pilots, is shot to death outside of a bar in Loiza, Puerto Rico.

### February

* February 1 – The Hall of Fame Special Committee on Veterans selects former commissioner Ford Frick and former players Earle Combs and Jesse Haines for enshrinement.
* February 4 – The Cincinnati Reds acquire southpaw hurler Bo Belinsky from the Pittsburgh Pirates for right-hander Dennis Ribant. Known as a free-wheeling bachelor in his earlier days with the Los Angeles Angels, Belinsky, 33, appears in three early-season games, the last of his MLB career, for the buttoned-up "Big Red Machine" before he's sent to Triple-A.
* February 18 – The Cleveland Indians acquire left-handed relief specialist Steve Mingori from the Reds for infielder Jay Ward.
* February 19 – Commissioner Bowie Kuhn announces the suspension of Detroit Tigers pitcher Denny McLain, effective April 1, for McLain's alleged involvement in a bookmaking operation. The suspension is indefinite, but will later be set at three months.

### March

* March 8 – With the Seattle Pilots' parent company, Pacific Northwest Sports, in bankruptcy court and the club's sale to a Milwaukee consortium headed by Bud Selig the only viable path forward, American League owners begin to weigh transferring the year-old team. The AL magnates are wary of angering the State of Washington's two powerful U.S. Senators, Scoop Jackson and Warren Magnuson, and endangering MLB's anti-trust exemption.
* March 17 – After almost two decades as president of the Brooklyn/Los Angeles Dodgers franchise, Walter O'Malley names his son, Peter, 32, to succeed him in the post. The elder O'Malley, who owns 75 percent of the Dodgers' stock, becomes chairman of the board.
* March 18 – The St. Louis Cardinals reveal that veteran third baseman Mike Shannon is suffering from a life-threatening ailment, a form of glomerulonephritis, in both kidneys. Hospitalized for nearly a month, Shannon, 30, is able to return to action May 14 and play 55 games for the Redbirds before the illness forces him back to the injured list in August, then an off-season retirement. He immediately joins the Cardinals' broadcast team, where he spends all or part of 50 years before his retirement in 2021 during the COVID-19 pandemic.
* March 21 – The Washington Senators trade outfielder Brant Alyea to the Minnesota Twins for pitchers Joe Grzenda and Charley Walters. Alyea, a reserve with Washington, will bat .415 for the Twins during the month of April with five home runs and 23 RBI in 17 games. Walters never pitches for the Senators, but when he retires from baseball he'll get a journalism degree and become a featured sports columnist for the St. Paul Pioneer Press.
* March 29 – The New York Mets deal veteran catcher J. C. Martin, an unsung contributor to their 1969 National League Championship Series and World Series triumphs, to the Chicago Cubs for catcher Randy Bobb.
* March 30 – The current edition of the Washington Senators signs free-agent, veteran right-handed pitcher Pedro Ramos, 34. Ramos returns to D.C., where he was a starting pitcher for the 1901–1960 Senators (now the Minnesota Twins) and known for his blazing fastball and prodigious games-lost totals: Ramos led the American League in that dubious category for four straight years (including one season in Minnesota), and between 1957 and 1961 he put up consecutive years of 16, 18, 19, 18 and 20 defeats.

### April

* April 1:
** The Milwaukee Brewers' parent company, headed by Bud Selig, purchases the Seattle Pilots franchise for $10.8 million. Although negotiations were conducted over a period of months, it was not until yesterday, March 31, when a federal bankruptcy judge declared the Pilots bankrupt; Brewers' tickets will go on sale tomorrow. Team equipment is shipped to Milwaukee County Stadium, where the Pilots' insignia is ripped off the uniforms and replaced by "Brewers," since there is no time for new ones to be made. The franchise remains in the American League West.
** On their first day as Milwaukee's team, the Brewers release left-hander Steve Barber. The former 20-game-winner, 32, will sign as a free agent April 23 with the Chicago Cubs.
* April 4 – The Milwaukee Brewers make another deal, sending infielder Frank Coggins, outfielder Roy Foster and cash to the Cleveland Indians for third baseman Max Alvis and outfielder Russ Snyder. Foster, 24, will bash 23 homers for the 1970 Tribe and finish second in the voting for American League Rookie of the Year.
* April 6:
** In the National League's 95th Opening Day, the Cincinnati Reds defeat the Montreal Expos 5–1 behind Jim Merritt's three-hitter and three home runs. It's the last opener at ancient Crosley Field, and the unofficial start of Cincinnati's Big Red Machine era that will produce five division titles, four NL pennants and two World Series championships over the next seven years.
** The American League's traditional Presidential Opener is delayed 55 minutes by rain, and Richard Nixon arrives in the middle of the first inning—missing his opportunity to throw out the first ball—as the Detroit Tigers' Mickey Lolich shuts out the Washington Senators 5–0.
* April 7:
** Milwaukee regains a Major League Baseball franchise of its own after a four-year absence as the Brewers play their first game, losing to the California Angels 12–0 before a crowd of 37,237 at County Stadium. The Wisconsin city had hosted 20 American League games played by the "homestanding" Chicago White Sox in 1968–1969.
** Pitcher Dave McNally strikes out 13 in nine innings as the Baltimore Orioles rip the Indians, 8–2, in Opening Day at Cleveland Stadium. The attack is led by Paul Blair, who drives in a pair of runs and scores three times. McNally holds the Indians to two runs on four hits and three walks to get the win. Rookie Roy Foster belts a two-run home run for the only offense for Cleveland.
** In Minnesota, left-fielder Brant Alyea leads the Twins over the Chicago White Sox, 12–0. His 4-for-4 day includes two homers and seven RBI, the latter setting a major league Opening Day record.
* April 8 – The Detroit Tigers release outfielder Tom Tresh. Tresh, 31, the American League Rookie of the Year in 1962, never plays in the majors again.
* April 11 – At Comiskey Park, Danny Walton hits the first two home runs in Milwaukee Brewers history, both two-run shots coming against White Sox starter Billy Wynne. The Brewers win for the first time, 8–4.
* April 18 – Nolan Ryan gives up only one hit in the first inning as he sets a then-New York Mets record by striking out 15 batters in a 7–0 victory over the Philadelphia Phillies at Shea Stadium.
* April 21 – At "The Launching Pad," Atlanta–Fulton County Stadium, the fast-starting Cincinnati Reds bash seven home runs, two by rookie Bernie Carbo, to defeat the Atlanta Braves 13–8.
* April 22:
** Four days after Ryan's strikeout feat, the New York Mets' Tom Seaver whiffs 19 San Diego Padres, including the last ten in succession, in winning 2–1. San Diego's Mike Corkins takes the loss. In the 20th century, no one had ever struck out ten batters in a row, a modern major league record. The Pads now have fanned 29 times in two games, a National League mark that will be topped in 1998 when the Houston Astro batters rack up 31 Ks in two days. Jerry Grote adds one foul fly catch to his 19 putouts via K's.
** At RFK Stadium, the Washington Senators go 18 innings to defeat the New York Yankees 2–1. Mike Epstein's sacrifice fly plates the game-winning run.
* April 24 – Tom Haller's RBI single drives in the game's only run in the home half of the 15th, as the Los Angeles Dodgers thwart the New York Mets 1–0. It's the longest of the Mets' 21 extra-inning games of 1970.
* April 27 – The California Angels trade third baseman Aurelio Rodríguez, 22, and outfielder Rick Reichardt, 27, to the Washington Senators for veteran third baseman Ken McMullen.
* April 29 – The Baltimore Orioles' Paul Blair, known for his brilliant defense in center field, slugs three home runs and drives in six in an 18–2 thrashing of the Chicago White Sox at Comiskey Park.

### May

* May 2:
** The Philadelphia Phillies' two top catchers, starter Tim McCarver and backup Mike Ryan, suffer broken fingers in the sixth inning against the San Francisco Giants at Candlestick Park. McCarver breaks a finger on his throwing hand when it's struck by a Willie Mays foul tip and is forced to leave the game. Ryan takes his place, and three batters later, Willie McCovey's slide into home breaks a finger on his gloved hand. Utilityman Jim Hutto takes over for Ryan. McCarver is out of action for four full months and appears in only 44 games in 1970. Ryan misses two full months. The Phillies will use six catchers during the season, including bullpen coach Doc Edwards.
** A 17-inning marathon at Municipal Stadium sees the Kansas City Royals edge the Cleveland Indians 4–3.
* May 10 – Hoyt Wilhelm of the Atlanta Braves makes his 1,000th MLB pitching appearance—the first pitcher in history to do so. The 47-year-old knuckleball artist, headed for the Baseball Hall of Fame, is in his 19th big-league season.
* May 11 – The California Angels and visiting Boston Red Sox go 16 innings to settle matters, with the Angels prevailing 2–1. Jarvis Tatum, who doubled, scores the winning run on a hit by Sandy Alomar Sr.
* May 12 – At Wrigley Field, Ernie Banks becomes the eighth member of the 500 home run club, connecting off Atlanta Braves pitcher Pat Jarvis during a 4–3, 11-inning Chicago Cubs win. It's also his 1,600th career run batted in. Ex-Cub Frank Secory is umpiring this game, as he was on September 20, 1953, when Banks hit his first career home run. Banks' teammate Billy Williams also homers in the ninth inning to tie the game, while Ron Santo's RBI single in the 11th wins it. Atlanta's Rico Carty, meanwhile, has three singles and has hit in 30 consecutive games.
* May 16 – A tragic event occurs during a game between the San Francisco Giants and the Los Angeles Dodgers at Dodger Stadium. Fourteen-year-old Alan Fish is sitting with friends when he's struck in the head by a foul ball off the bat of Dodger outfielder Manny Mota. Fish dies from his injury four days later, becoming the first fan to die from a foul ball strike in major league history.
* May 17 – In the second game of a double header, Hank Aaron of the Atlanta Braves collects his 3,000th career hit with an infield single as well as his 517th home run off of pitcher Wayne Granger, during a 7–6, 15-inning loss to the Cincinnati Reds. In doing so, Aaron becomes the founding member of the 3,000 hits/500 home runs club. In later years, Willie Mays, Eddie Murray, Rafael Palmeiro, Albert Pujols and Alex Rodriguez will join the select circle.
* May 23 – At Candlestick Park, the San Diego Padres defeat the San Francisco Giants, 17–16, in 15 innings on Steve Huntz's home run; the teams combine for 44 hits and four errors. The loss drops the Giants' record to 19–23, fourth in the NL West and 12½ games behind Cincinnati. After the game, they fire second-year manager Clyde King and promote Charlie Fox from Triple-A Phoenix to replace him.
* May 31 – Protecting an eighth-inning 6–1 lead and aiming for his eighth save of 1970, California Angels sophomore ace relief pitcher Ken Tatum throws an inside fastball that strikes Baltimore Orioles outfielder Paul Blair in the face, breaking multiple bones in Blair's nose, cheekbone and eye socket. Remarkably, Blair only misses three weeks of action and returns to the Oriole lineup June 21. Tatum, however, will never be the same. Including today's game, his MLB career totals to date are a 9–3 won–lost record in 65 games pitched, with 30 saves; he's allowed 69 hits and 16 earned runs in 1092⁄3 innings pitched (for an ERA of 1.31) with 81 strikeouts. But, horrified at the injury he has inadvertently caused, Tatum will stop throwing inside to hitters. His performance will decline, the Angels will trade him, and he'll also suffer a broken cheekbone during batting practice in 1971, among other injuries. Tatum's career ends in 1974 with a 16–12 mark (2.93 ERA) and 52 saves in 176 appearances.

### June

* June 1 – After a national magazine prints excerpts from Ball Four, his soon-to-be-published diary of the 1969 season, Houston Astros pitcher Jim Bouton is called on the carpet by Commissioner of Baseball Bowie Kuhn to "express [his] displeasure" with the book's contents, which reveal private conversations and behaviors—including alcohol and drug use and sexual promiscuity—among major-league players. Kuhn's criticism is mild compared to the stream of vitriol directed at Bouton by others in baseball, but the book (published later this month) becomes a "groundbreaking tome" in sports literature. Meanwhile, Bouton pitches ineffectively for Houston (4–6, 5.40 ERA in 29 appearances), and is sent to the minors after July 29.
* June 5 – At age 19 and two months, Bert Blyleven makes his major league debut with the Minnesota Twins, and gives up a lead-off home run to Washington Senators outfielder Lee Maye. Then the teenager holds on for a 2–1 victory, the first of a 287-win career that will propel his induction into the Baseball Hall of Fame.
* June 7 – The Kansas City Royals fire first-year skipper Charlie Metro and replace him with pitching coach Bob Lemon. The Royals are 19–33 and fifth in the six-team American League West.
* June 8 – Major League Baseball players and management agree to end their labor dispute by settling on a new standard contract. Among the compromises that benefit the players is a raise in the minimum league salary from $10,000 to $12,000 per season.
* June 11
** Faced with attendance woes at War Memorial Stadium, the 84-year-old Buffalo Bisons, who have played continuously since 1886 and in the International League since 1912, give up the ghost and move to Winnipeg, Manitoba, where they are re-christened the Winnipeg Whips. The Triple-A affiliate of the second-year Montreal Expos has lost 35 of its first 45 games. Buffalo will be without Organized Baseball until 1979, when a new Bisons franchise is founded in the Double-A Eastern League.
** The Oakland Athletics trade veteran southpaw Al Downing and outfielder Tito Francona to the Milwaukee Brewers for outfielder Steve Hovley.
* June 12:
** In the first game of a doubleheader at San Diego Stadium, Dock Ellis of the Pittsburgh Pirates no-hits the San Diego Padres 2–0. Years later, Ellis will claim that he is under the influence of LSD during the entire game.
** The 43–16 Cincinnati Reds widen their NL West lead to ten full games and 21-year-old rookie right-hander Wayne Simpson improves to 9–1 with a complete-game, 3–1 triumph over the Philadelphia Phillies at Connie Mack Stadium. A two-run homer by future Hall-of-Famer Tony Pérez—his 23rd of the season—is decisive.
* June 13:
** The Kansas City Royals acquire second baseman Cookie Rojas from the St. Louis Cardinals for rookie outfielder Fred Rico. Rojas, 31, will make four American League All-Star teams over 7½ seasons as a Royal.
** The disappointing, 26–29 Cardinals also ship pitcher George Culver to the Houston Astros for infielder Leon McFadden and outfielder Jim Beauchamp.
* June 15:
** Among a flurry of deals they make at the trading deadline, the Milwaukee Brewers sell the contract of veteran relief pitcher Bob Locker to the Oakland Athletics and acquire reserve outfielder Dave May from the Baltimore Orioles for pitchers Dick Baney and Buzz Stephen. Locker will thrive in Oakland and win a 1972 World Series ring. May earns a regular job in Milwaukee and becomes a 1973 AL All-Star.
** The Orioles reacquire relief pitcher Moe Drabowsky, a 1966 World Series hero, from the Kansas City Royals for infielder Bobby Floyd. In doing so, they give Drabowsky the chance to earn a second World Series ring.
* June 17 – At Candlestick Park, Ernie Banks and Willie Mays become the first 500 home run club members to each homer in the same game. In the eighth inning of the Chicago Cubs' game against the San Francisco Giants, Banks hits his 504th career home run, a three-run shot off Giant reliever Mike Davison. Mays then hits his 615th career home run off the Cubs' Ken Holtzman in the bottom half of the same inning. The Cubs defeat the Giants, 6–1.
* June 19 – Mike Shannon's two run single in the top of the 17th inning stands up as the winning margin in the St. Louis Cardinals' 5–3 triumph over the Chicago Cubs at Wrigley Field. The victory goes to rookie Al Hrabosky, who fans three over two innings in his second MLB appearance.
* June 21 – The Detroit Tigers' César Gutiérrez gets seven hits in seven at bats in 12 innings against the Cleveland Indians, setting an American League mark and tying a major league record for most hits in one game. The light-hitting Gutiérrez raises his batting average from .218 to .249.
* June 23:
** The Montreal Expos acquire right-hander Mike Marshall, 27, from the Houston Astros for outfielder Don Bosch. Marshall has bounced from the Detroit Tigers to the Seattle Pilots to Houston since 1967, but in Montreal he will develop into a record-setting relief pitcher.
** The Atlanta Braves sell the contract of veteran hurler Milt Pappas to the Chicago Cubs.
* June 24:
** In a 7–2 loss to the Cleveland Indians in the first game of a doubleheader at Yankee Stadium, New York Yankees pitcher Steve Hamilton gets Indians batter Tony Horton to foul out on a pitch known as the "Folly Floater".
** The Cincinnati Reds defeat the San Francisco Giants, 5–4, in the final game that the Reds will play at Crosley Field, built in 1912. Lee May's game-winning, eighth-inning home run is the last hit in the venerable ballpark's history.
* June 26 – Frank Robinson of the Baltimore Orioles hits grand slams in consecutive innings, the fourth and fifth, in a 12–2 victory over the Washington Senators at Robert F. Kennedy Stadium. The same runners are on base both times: Dave McNally on third, Don Buford on second and Paul Blair on first.
* June 28 – The Pittsburgh Pirates defeat the Chicago Cubs in both games of a doubleheader, 3–2 and 4–1, in the last two games played at Forbes Field, which opened in 1909. A ninth-inning single in the nightcap by the Cubs' Willie Smith is the last safety recorded in the old ball-yard.
* June 30 – Riverfront Stadium opens with the Cincinnati Reds losing to the Atlanta Braves, 8–2. Atlanta second baseman Félix Millán's first-inning single is the inaugural base hit in the multi-purpose facility; he then rides home on Riverfront's first home run, hit by Hank Aaron.

### July

* July 1:
** With 53,863 on hand at Tiger Stadium, Detroit's Denny McLain returns from his three-month suspension on gambling allegations by throwing 51⁄3 innings against the New York Yankees. He allows five earned runs on eight hits, including homers by Jerry Kenney, Thurman Munson and Bobby Murcer, and departs with his club trailing 5–3. McLain doesn't get tagged with a loss when Tigers go on to rally and win in extra innings. But it signals a downturn for 1968's MVP and Cy Young Award winner; he pitches poorly, and is suspended twice in September, the latter time for carrying a gun on the team's airplane.
** The St. Louis Cardinals trade well-traveled relief pitcher Ted Abernathy to the Kansas City Royals for fellow right-hander Chris Zachary.
* July 2:
** In the following game of the Yankees–Tigers series at Detroit, the Tigers' Joe Niekro pitches 81⁄3 innings of no-hit baseball until a one-out single by Horace Clarke breaks up the gem with the only safety Niekro will allow in a 5–0 victory. It's the third no-hit bid that Clarke has spoiled in the ninth inning in less than a month; earlier, he had foiled bids by Jim Rooker on June 4 and Sonny Siebert (who had already pitched a no-hitter in 1966) on June 19.
** John Bateman of the Montreal Expos sets a team record with seven runs batted in to pace the Expos to a 13–10 victory over the St. Louis Cardinals. His feat includes a grand slam in the Expos' six-run first inning.
** The Kansas City Royals sign 20-year-old undrafted amateur free agent Frank White, a future eight-time Gold Glove Award-winning second baseman and five-time American League All-Star. The signing is also significant because White is a graduate of the experimental Kansas City Royals Baseball Academy, founded by owner Ewing Kauffman to train elite athletes like White with limited baseball experience. White will be the most illustrious alumnus of the Academy, which shuts down in 1974.
* July 3:
** Clyde Wright of the California Angels has a doubly memorable day. In a ceremony before the Angels' game against the Oakland Athletics at Anaheim Stadium, the former star pitcher at Carson-Newman College (with whom he won an NAIA Baseball World Series title in 1965) is inducted into the NAIA Hall of Fame. He then no-hits the Athletics 4–0, the first no-hitter in the stadium's history.
** At Wrigley Field, the Pittsburgh Pirates and Chicago Cubs combine for 40 hits and 30 runs in a nine-inning game. The Pirates prevail in both categories, winning 16–14 on the strength of 22 hits, including six home runs.
* July 4 – The pennant races at the season's traditional halfway point show the defending World Series champion New York Mets (42–36) one-half game in front of the Pittsburgh Pirates (43–38) in the NL East. The next-closest races are in the American League, where the Baltimore Orioles (49–30) lead the New York Yankees (44–33) in the AL East and the Minnesota Twins (48–26) outpace the California Angels (46–32) in the AL West; in each case the division leader boasts a four-game bulge over its nearest rival. The only runaway division is the NL West, where the Cincinnati Reds (56–23) lead the second-place Los Angeles Dodgers (46–32) by 9½ games. The nickname "Big Red Machine," coined on July 4, 1969, by a Cincinnati baseball writer, is now being used widely by commentators throughout baseball.
* July 8 – San Francisco Giants third baseman Jim Ray Hart ties a modern Major League record with six runs batted in during one inning. All come in the fifth, with Hart slamming a three-run home run and three-run triple in the frame. He eventually completes his record-setting day by hitting for the cycle en route to a 13–0 victory over the Atlanta Braves.
* July 14 – At Riverfront Stadium, the National League wins its eighth straight All-Star Game, a 12-inning 5–4 victory. Pete Rose crashes into Cleveland Indians catcher Ray Fosse to score the winning run on Jim Hickman's single. Fosse, who never had the ball, hurts his right shoulder and is taken to the hospital. This All-Star Game had seen voting returned to the fans via punch-card ballots distributed in major league ballparks, and is the first Midsummer Classic since 1958 for which the squads were not entirely selected by managers, coaches and players.
* July 16 – Pittsburgh's Three Rivers Stadium opens to the public, but the Cincinnati Reds spoil the party by defeating the Pirates, 4–3, before a crowd of 48,846. The first hit at the stadium is a single by Pittsburgh's Richie Hebner. The first home run at the new ballpark is struck by Cincinnati's Tony Pérez.
* July 18 – Willie Mays of the San Francisco Giants records his 3,000th career hit.
* July 20:
** At Dodger Stadium, Bill Singer of the Los Angeles Dodgers no-hits the Philadelphia Phillies, 5–0. Singer's catcher, Jeff Torborg, had caught Sandy Koufax's perfect game in 1965, and will later catch the first of Nolan Ryan's seven no-hitters, in 1973.
** The San Francisco Giants and New York Yankees swap left-handed pitchers, with the Giants sending former Cy Young Award winner Mike McCormick, 31, to New York for John Cumberland, 23.
* July 26 – Johnny Bench of the Cincinnati Reds belts three straight home runs off St. Louis Cardinals pitcher Steve Carlton. On the same day, Orlando Cepeda, of the Atlanta Braves, also connected three consecutive homers in an 8–3 victory over the Chicago Cubs. Bench, Carlton and Cepeda are future Hall of Famers.
* July 29 – The 51–49 Cubs, only four games out of first place in the NL East, purchase the contract of first baseman Joe Pepitone from the Houston Astros.

### August

* August 1 – At Atlanta–Fulton County Stadium, Willie Stargell of the Pittsburgh Pirates hits three doubles and two home runs in the Pirates' 20–10 win over the Atlanta Braves. He becomes the third player in modern-day Major League history to collect five extra-base hits in one game, Lou Boudreau and Joe Adcock having done so in 1946 and 1954 respectively. Coincidentally, this game was nationally broadcast, and the trivia question early in the contest was to name the two players who had gotten five extra-base hits in a game. Bob Robertson also collects five hits for the Pirates, including a home run; not until Andrew McCutchen and Garrett Jones in 2010 will two Pirates collect five hits each in the same game.
* August 2 – The Pittsburgh Pirates' Bob Robertson lashes a two-run double and then follows with two 400-foot homers, driving in a total of six runs as the Pirates beat the Atlanta Braves 10–7.
* August 10 – At Fenway Park, the Detroit Tigers almost overcome a ninth-inning 11–3 deficit, scoring seven runs (five of then unearned) off Sonny Siebert and Sparky Lyle before Chuck Hartenstein whiffs Bill Freehan to preserve the Boston Red Sox' 11–10 victory.
* August 11:
** Philadelphia's Jim Bunning beats the Houston Astros 6–5 to become the first pitcher to win 100 games in both leagues since Cy Young.
** The St. Louis Cardinals erase 8–2 and 10–6 deficits by scoring five times in the bottom of the ninth to defeat the San Diego Padres 11–10. Carl Taylor caps the Redbird comeback by smashing a three-run walk-off home run.
* August 19 – Ferguson Jenkins throws a complete game and hits his second homer of the season in the Chicago Cubs' 12–2 triumph over the visiting Padres. The Cubs belt seven home runs on the day, including two from Jim Hickman.
* August 22 – Roberto Clemente singles, steals second, and scores on a hit by Jerry May, giving the visiting Pittsburgh Pirates a clutch 2–1, 16-inning victory over the Los Angeles Dodgers.
* August 30:
** Nine different players—five California Angels and four Cleveland Indians—hit home runs in the Angels' 10–9 triumph over Cleveland at Municipal Stadium.
** At Comiskey Park, three different Boston Red Sox players (Mike Andrews, Reggie Smith and George Scott) have four-hit games, enabling their club to overwhelm the Chicago White Sox, 21–11. Scott and Carl Yastrzemski hit home runs.
* August 31 – The second-place Angels, only three games in arrears of the Minnesota Twins in the AL West, purchase the contract of veteran outfielder Tony González from the Atlanta Braves.

### September

* September 3 – Billy Williams of the Chicago Cubs asks to be kept out of the lineup, snapping his National League record of 1,117 consecutive games played. His record will be broken in 1983 by Steve Garvey.
* September 4 – The Chicago White Sox continue their management makeover by appointing Roland Hemond director of player personnel and Chuck Tanner field manager. Both come from the California Angels' organization, where Tanner had led the 1970 Hawaii Islanders of the Pacific Coast League to a 98–48 record. He becomes the White Sox' permanent skipper, succeeding the fired Don Gutteridge, when he takes the reins September 18. In the midst of a nightmarish 56–106 season, the ChiSox began their housecleaning September 1 when Stu Holcomb replaced Ed Short as general manager and Gutteridge was released.
* September 7 – The Labor Day leaderboard shows a "dogfight" in the National League East Division, where the Pittsburgh Pirates (75–65) lead the New York Mets (73–66) by 1½ games and the Chicago Cubs (73–67) by two. The other pennant races aren't so close: in the AL West, the Minnesota Twins (83–55) now lead the second-place Oakland Athletics (78–62) by six and the third-place California Angels (76–63) by 7½; and the Baltimore Orioles (89–51) and Cincinnati Reds (90–53) are running away with their divisions, with the Orioles nine games ahead of the New York Yankees (80–60) in the AL East and the Reds 11 games in front of the Los Angeles Dodgers (77–62) in the NL West.
* September 10 – At Shea Stadium, Cleon Jones' 14th-inning triple drives home Tommie Agee with the winning run and newly acquired reliever Ron Herbel gets the win, as the Mets edge the Philadelphia Phillies 3–2 and move into a flat-footed tie with the Pirates in the NL East. The Cubs are only one game back. Nineteen games remain in the regular season for the three contenders.
* September 14 – Bolstering their bullpen for the season's final stretch, the Pirates obtain pitcher Mudcat Grant from the Oakland Athletics for young outfielder Ángel Mangual ("PTBNL"). Former 20-game-winner Grant, now 35, has become one of MLB's top relief pitchers, with a 6–2 (1.82 ERA) record and 24 saves for Oakland.
* September 16:
** Minnesota Twins pitcher Bert Blyleven strikes out the first six California Angels batters off the game, and ties a major league record. Blyleven will finish the game with ten strikeouts, but take the 5–1 loss.
** The Oakland Athletics deal another key player to a National League East Division contender, selling the contract of outfielder Tommy Davis, 31, to the Chicago Cubs, who are tied for second place and two games from the lead.
* September 17 – Although they bow 2–0 to the Washington Senators, the Baltimore Orioles clinch their second straight AL East title when the Boston Red Sox eliminate the New York Yankees by downing the Bombers 5–4 in The Bronx. Meanwhile, the idle Cincinnati Reds win their first NL West crown when their closest rival, the Los Angeles Dodgers, are soundly beaten 10–5 by the Houston Astros.
* September 18 – In the NL East's version of an "arms race," the New York Mets purchase the contract of veteran former two-time 20-game-winner and Cy Young Award recipient Dean Chance, 29, from the Cleveland Indians. The Mets are 2½ games behind the Pittsburgh Pirates (who defeat them 3–2 at Shea Stadium today behind Steve Blass) with a dozen games to play.
* September 21:
** At Oakland–Alameda County Coliseum, 21-year-old Vida Blue of the Athletics no-hits the Minnesota Twins 6–0, the only baserunner coming on Harmon Killebrew's second-inning walk. The no-hitter caps a season that witnesses four no-hitters, all pitched in California-based big-league stadiums; Candlestick Park is the only one of the five not to host a no-hitter. It is also the second time in three seasons an Oakland pitcher has no-hit the Twins, who were on the losing end of Catfish Hunter's perfect game in 1968.
** The Chicago Cubs, two games from the NL East lead today with ten to play, acquire 47-year-old future Hall-of-Fame hurler Hoyt Wilhelm from the Atlanta Braves. In Chicago, Wilhelm is reunited with Leo Durocher, who managed the knuckleballer when he was a rookie with the 1952 New York Giants.
* September 22 – One day after being no-hit, the Twins register a 5–3 win over the second-place Athletics to clinch the American League West. They claim the division title on exactly the same date as they had in 1969.
* September 27:
** There are no miracles in 1970 for the reigning World Series champion New York Mets, as the Pittsburgh Pirates capture the National League East with a 2–1 victory over the Mets before the largest crowd in brand-new Three Rivers Stadium history (50,461). New York strands 12 baserunners during the loss.
** The second-ever League Championship Series matchups are determined. While the 1970 ALCS will feature a return engagement between 1969's combatants, the Baltimore Orioles and Minnesota Twins, the 1970 NLCS will feature two teams who haven't made the postseason since the early 1960s: the Pirates, who won the 1960 World Series, and Cincinnati Reds, winners of the 1961 NL pennant. Roberto Clemente and Bill Mazeroski, both future Hall of Famers, remain from the Bucs' 1960 champions. Seldom-used Jim Maloney, Cincinnati's former mound ace, is the lone survivor of 1961's league champs.

### October

* October 1:
** With two hits in three at bats, California Angels outfielder Alex Johnson (.3289) edges Carl Yastrzemski of the Boston Red Sox (.3286) for the American League batting crown. Nevertheless, 1970 is a strong season for Yastrzemski, who leads the AL in runs scored, slugs 40 homers, collects 102 RBI, and is the MVP of the 1970 Major League Baseball All-Star Game.
** Vic Davalillo of the St. Louis Cardinals breaks the National League single-season pinch hitting record and ties the Major League record with his 24th pinch hit of the year.
** The Philadelphia Phillies defeat the Montreal Expos 2–1 in 10 innings in the final game at Connie Mack Stadium, which opened as Shibe Park in 1909. The occasion is marred when fans literally dismantle the stadium while the game is still in progress. A special post-game ceremony — including a helicopter delivery to Veterans Stadium of home plate — is cancelled. The North Philadelphia ballyard is the third venerable National League park to close during 1970.
* October 2:
** Oakland Athletics owner Charles O. Finley switches managers again, firing John McNamara after a second-place finish and hiring former Boston Red Sox pilot Dick Williams as his successor. It's Finley's tenth managerial change in ten full seasons as owner of the Athletics franchise—but it will be the most successful. Williams will last three seasons under Finley and produce one American League West champion in 1971, then World Series titles in both 1972 and 1973. Williams will enter the Baseball Hall of Fame in 2008 as a result.
** One day after their disappointing season ends, the Detroit Tigers shake up their field leadership by firing manager Mayo Smith and replacing him with Billy Martin. Smith had led Detroit to the 1968 World Series championship. For Martin, the Tigers become the second stop on what will be a tumultuous, 16-year managerial career.
* October 5:
** The Baltimore Orioles and Cincinnati Reds reach the World Series by sweeping away their opponents, the Minnesota Twins and Pittsburgh Pirates, in their respective best-of-five League Championship Series. All four LCS matchups since divisional play was launched in 1969 have now produced decisive, three-games-to-none results.
** The St. Louis Cardinals trade first baseman Dick Allen to the Los Angeles Dodgers for second baseman Ted Sizemore and catcher Bob Stinson. Allen's one season as a Cardinal yields 34 homers, 101 RBI and an All-Star nod, but he plays in only 122 games.
* October 9 – In a trade that will be momentous for both teams, the Detroit Tigers deal former MVP and Cy Young Award winner Denny McLain, fellow hurler Norm McRae, third baseman Don Wert and outfielder Elliott Maddox to the Washington Senators for hurlers Joe Coleman and Jim Hannan, shortstop Ed Brinkman and third baseman Aurelio Rodríguez. McLain had gone only 3–5 (4.63) in 14 games in 1970 after spending the first half of the season under suspension for alleged gambling-related offenses—this after he had won a combined 55 games in 1968 and 1969. In Washington, his performance will continue to deteriorate in 1971, as he loses 22 of 32 decisions and fails to provide the drawing power the Senators vitally need; they will move to Arlington, Texas, after the season and become the Texas Rangers in 1972. Meanwhile, Coleman moves to the top of the Tiger rotation, winning 62 games from 1971–1973, and Brinkman and Rodríguez will anchor the left side of the Detroit infield through 1974.
* October 11 – The Boston Red Sox trade 25-year-old local star Tony Conigliaro (36 HR, 116 RBI, .266) to the California Angels, along with pitcher Ray Jarvis and catcher Jerry Moses, for pitcher Ken Tatum, second baseman Doug Griffin and outfielder Jarvis Tatum. Hampered by poor vision after a beanball struck him in the face in August 1967, Conigliaro will play only 74 games for the 1971 Angels before retiring.
* October 12 – The Houston Astros and Chicago Cubs exchange shortstops when Houston acquires 23-year-old prospect Roger Metzger for Héctor Torres. Metzger will be the Astros' regular shortstop until 1977; although he will struggle offensively, he will win an NL Gold Glove Award in 1973.
* October 13 – The Chicago White Sox trade first baseman Gail Hopkins and outfielder John Matias to the Kansas City Royals for pitcher Don O'Riley and outfielder Pat Kelly.
* October 15 – For the third time in the 1970 World Series, the Baltimore Orioles overcome a 3–0 deficit to bury the Cincinnati Reds 9–3 in Game 5 of the Fall Classic, and win the world championship, four games to one. Frank Robinson and Merv Rettenmund each homer and drive in two runs. Third baseman Brooks Robinson, the "human vacuum cleaner", easily wins the Series MVP award.
* October 20 – The Milwaukee Brewers trade pitchers George Lauzerique and Jessie Huggins and catcher Jerry McNertney to the St. Louis Cardinals for left-hander Jim Ellis and catcher Carl Taylor.
* October 21 – The Cardinals acquire their 1950s "bonus baby" Ducky Schofield for the third time in the infielder's career, this time from the Boston Red Sox for first baseman/outfielder Jim Campbell. Schofield, now 35 and an 18-year MLB veteran, formerly played for the Redbirds from 1953–1958 and in 1968.

### November

* November 3 – The Washington Senators acquire six-time Gold Glove Award and three-time National League All-Star centerfielder Curt Flood from the Philadelphia Phillies in a five-player transaction. Flood, 32 and then still in his prime, sat out the entire 1970 campaign while he legally challenged the reserve clause; he never donned a Phillie uniform. He will be the Senators' Opening Day centerfielder in 1971, but appear in only 13 games and play poorly. He leaves the team, and Major League Baseball, on April 26.
* November 10 – Boog Powell, first baseman for the American League and World Series champion Baltimore Orioles, is selected AL MVP. Powell (.297, 35 HR, 114 RBI, and named to his fourth All-Star team) beats out two future Hall of Famers from the Minnesota Twins, Tony Oliva and Harmon Killebrew.
* November 18 – Cooperstown-bound catcher Johnny Bench of the National League champ Cincinnati Reds garners 22 of 24 first-place votes to grab the 1970 NL MVP Award.
* November 21 – New York Mets outfielder Tommie Agee became the first non-pitcher to win a Gold Glove in both leagues. Agee also won the honor with the Chicago White Sox during his 1966 rookie of the year season.
* November 25 – New York Yankees catcher Thurman Munson receives 23 of 24 first-place votes and is named American League Rookie of the Year. Munson batted .302 with six home runs and 53 RBI in 132 games during the regular season. Cleveland Indians outfielder Roy Foster (.268, 23, 60) is also named on a first place ballot.
* November 27 – Pitcher Carl Morton, who posted an 18–11 record with 154 strikeouts and a 3.60 ERA for the last-place Montréal Expos, receives the National League Rookie of the Year Award. Morton beats out Cincinnati Reds outfielder Bernie Carbo, who hit .310 with 21 home runs and 63 RBI.
* November 30:
** The California Angels trade pitcher Tom Bradley, catcher Tom Egan and outfielder Jay Johnstone to the Chicago White Sox for pitcher Billy Wynne, infielder Syd O'Brien and outfielder Ken Berry. Bradley, 23, will win 15 games for the Pale Hose in both 1971 and 1972.
** The Chicago Cubs acquire brothers Hal and Danny Breeden in two separate transactions. First baseman Hal, 26, comes from the Atlanta Braves, who reacquire veteran knuckleballer Hoyt Wilhelm in the deal. Catcher Danny, 28, arrives from the Cincinnati Reds in exchange for outfielder Willie Smith.

### December

* December 1:
** The world-champion Baltimore Orioles acquire starting pitcher Pat Dobson and relief pitcher Tom Dukes from the San Diego Padres for pitchers Tom Phoebus, Fred Beene and Al Severinsen and shortstop Enzo Hernández. In 1971, Dobson will win an even twenty games and join Mike Cuellar, Jim Palmer and Dave McNally as one of four 20-game-winners on the Oriole mound staff.
** The Boston Red Sox trade second baseman Mike Andrews and shortstop Luis Alvarado to the Chicago White Sox in exchange for 36-year-old, future Hall of Fame shortstop Luis Aparicio.
** The Atlanta Braves trade veteran third baseman Bob Aspromonte to the New York Mets for relief pitcher Ron Herbel. Native Brooklynite Aspromonte, 32, will become the last member of the Brooklyn Dodgers to appear in an MLB game on September 28, 1971.
* December 2 – The Kansas City Royals acquire shortstop Freddie Patek, pitcher Bruce Dal Canton and catcher Jerry May from the Pittsburgh Pirates for fire-balling pitcher Bob Johnson, catcher Jim Campanis and shortstop Jackie Hernández. The 5 ft 5 in (1.65 m) Patek will hold down Kansas City's shortstop job for nine years and be selected to three American League All-Star teams.
* December 11 – The Cleveland Indians trade lefty-swinging catcher Duke Sims to the Los Angeles Dodgers for pitchers Alan Foster and Ray Lamb.
* December 15 – Jim Maloney, the Cincinnati Reds' ace starting pitcher for much of the 1960s, is traded to the California Angels for southpaw reliever Greg Garrett. Maloney, 30, threw two no-hitters and twice won 20 or more games in a Cincinnati uniform. In 1971, he will appear in only 13 games as an Angel during his final MLB season.
* December 16 – The Baltimore Orioles trade outfielder and minor-league slugger Roger Freed to the Philadelphia Phillies for left-hander Grant Jackson, utilityman Jim Hutto and outfielder Sam Parrilla.
* December 17 – Marvin Milkes resigns as general manager of the Milwaukee Brewers. Milkes, who had moved to Wisconsin with the Seattle Pilots in April, was a frequent target of Jim Bouton's derision in Bouton's recently-published memoir, Ball Four.
* December 28 – The Montreal Expos acquire second baseman Ron Hunt from the San Francisco Giants for first baseman Dave McDonald. As an Expo for just short of four full seasons, Hunt will continue his streak of leading the National League in being hit by a pitch into 1974, including an MLB-record 50 HBPs in 1971.
