# 2019 Major League Baseball season

The 2019 Major League Baseball season began on March 20, while the regular season ended on September 29. It was the 150th anniversary of professional baseball, dating back to the 1869 foundation of the Cincinnati Red Stockings. The postseason began on October 1. The World Series began October 22 and ended October 30 with the Washington Nationals defeating the Houston Astros in seven games to win their first World Series championship. The entire schedule was released on August 22, 2018.
The 90th Major League Baseball All-Star Game was held on July 9 at Progressive Field, home of the Cleveland Guardians. The American League won, 4–3, for its seventh straight victory.
This was the final season when anyone on the 40-man expanded roster could be used in games from September 1 through the end of the regular season (so-called September call-ups).

## Schedule

As has been the case since 2013, teams were scheduled to play 19 games against each division opponent for a total of 76 games, and six or seven games against each team from the other two divisions for a total of 66 games. The primary inter-league match-ups were AL East vs NL West, AL Central vs NL East and AL West vs NL Central.
The season began on March 20 and 21 with the Oakland Athletics and the Seattle Mariners playing in Tokyo, Japan, at the Tokyo Dome.
Excluding international openers, March 28 was the earliest Opening Day in history. The previous earliest date was March 29 of the 2018 season.
The second annual Mexico Series of games featured four matchups during the season. The first featured the St. Louis Cardinals and the Cincinnati Reds at Monterrey, Mexico's Estadio de Béisbol Monterrey on April 13 and 14. The other series, also in Monterrey, featured two games between the Houston Astros and the Los Angeles Angels on May 4 and 5.
The Kansas City Royals faced the Detroit Tigers at Charles Schwab Field Omaha in Omaha, Nebraska, on June 13 for the MLB in Omaha game, only two days before the College World Series. This was the first MLB game played in the state of Nebraska.
The London Series featured the New York Yankees and Boston Red Sox at London Stadium in London, on June 29 and 30 making it the first regular season series played in London, under a two-year commitment.
The MLB Little League Classic at Muncy Bank Ballpark at Historic Bowman Field in Williamsport, Pennsylvania, coinciding with the Little League World Series, returned to the schedule for the third straight year. It was played between the Chicago Cubs and Pittsburgh Pirates on August 18.

## Spring training

Spring training for the 2019 season began in late February and lasted through late March. Teams began workouts and practice for spring training beginning in mid February. Pitchers and catchers reported first, followed by position players a few days later.
Prior to the start of the regular season, each team played between 22 and 35 spring training games, beginning on February 22. There were several times during spring training where a team had two different squads playing different teams simultaneously. In addition to spring training games, teams occasionally played exhibition games with non-MLB teams, such as Minor League Baseball teams, independent teams, or college teams. These exhibition games were not counted in spring training standings. Spring training ended on March 26, two days before the Opening Day.

## Uniforms
### Changes

On November 16, 2018, the Miami Marlins unveiled a new logo, team colors, and uniform for 2019, as part of changes instituted by the team's new CEO Derek Jeter. The new design replaces one used since their 2012 move to Marlins Park and rebranding from the Florida Marlins to the Miami Marlins, and utilizes shades of red, blue, black, and slate.
On January 29, 2018, Major League Baseball stated that the Cleveland Indians had agreed to stop using their "Chief Wahoo" logo—which has attracted controversy as a stereotype of Native Americans—on their uniforms in 2019, as it was deemed to be "no longer appropriate for on-field use". The block C cap insignia will officially become the team's main logo; on November 19, 2018, the team unveiled new uniforms excluding the Chief Wahoo logo, as well as new hats with red brims for home games, a new red-colored home alternate jersey (marking the team's first red jersey since the 1970s), and sleeve patches commemorating their hosting of the 2019 All-Star Game. In order to maintain trademarks and prevent it from falling into the public domain, the logo will continue to be used on a limited amount of team merchandise.
All 30 teams wore patches this year on the right sleeve commemorating MLB's 150th anniversary. The patch was also featured on caps on Opening Day.

## Venues

This was the Texas Rangers' final season at Globe Life Park in Arlington (formerly known as the Ballpark in Arlington and Ameriquest Field), where the team played its final regular season home game with a 6–1 win over the New York Yankees on September 29 before moving to Globe Life Field in 2020.
The stadium of the Seattle Mariners was renamed T-Mobile Park for the mobile provider (including its magenta-pink logo color as part of the park's branding atmosphere), after Safeco's contract with the team to call the venue Safeco Field expired at the end of the 2018 season.
The home field of the San Francisco Giants had its fourth name in its history since opening in 2000, but its first name outside the same company, as Oracle will pay an unknown but significant amount for a twenty-year agreement to rename the former AT&T Park as Oracle Park. It also keeps Oracle's name on a Bay Area sports venue, as the Golden State Warriors left Oakland's Oracle Arena for the Chase Center .75 miles (1.2 km) south of Oracle Park at the end of the 2018–19 NBA season.

## Broadcast rights
### Television
#### National

This was the sixth year of the current eight-year deals with Fox Sports, ESPN, and TBS. Fox aired eight weeks of baseball on Saturday Nights which led up to the 2019 Major League Baseball All-Star Game which also aired on Fox. Fox then televised Saturday afternoon games for the final four weeks of the season. FS1 televised games on Tuesday and on Saturday both during the afternoon and night. ESPN televised games on its flagship telecast Sunday Night Baseball as well as Monday and Wednesday nights. TBS televised Sunday afternoon games for the last 13 weeks of the regular season. Fox and ESPN Sunday Night Baseball telecasts were exclusive; all other national telecasts were subject to local blackout.
TBS televised the National League Wild Card Game, Division Series, and the Championship Series. ESPN televised the American League Wild Card. FS1 and MLB Network televised the American League Division Series. Fox and FS1 televised the American League Championship Series. The World Series will air exclusively on Fox for the 20th consecutive year.
On April 30, 2019, Major League Baseball and YouTube agreed to a partnership for 13 exclusive baseball games. The agreement was essentially a replacement to an earlier deal with Facebook Watch, which was criticized for requiring a Facebook account to access and for having too clunky of an interface. The YouTube games would feature a pre and post game show, alongside the game, all produced by MLB Network. There was no requirement for a YouTube account to access the game. The first game aired was between the Phillies and the Dodgers on July 18, 2019. After the season, MLB said they averaged 130,000 viewers per telecast. The August 7, Dodgers-Cardinals telecast saw the highest peak of 320,000 live viewers.

#### Local

Under an agreement with the U.S. Department of Justice regarding Disney's acquisition of 21st Century Fox, the Fox Sports Regional Networks were required to be sold off to third parties by June 18, 2019. Fox also invoked a clause to give Yankee Global Enterprises the rights to buy their stake back in the YES Network. Including YES, the Fox Sports Regional Networks broadcast games for 15 of the 30 MLB teams. On March 8, YES was sold to a consortium including Yankee Global Enterprises, Amazon, and Sinclair Broadcast Group for $3.5 billion. Then on May 3, Sinclair and Entertainment Studios agreed to purchase the rest of the Fox Sports Regional Networks. The networks continued to use the Fox Sports branding for the rest of the regular season under a transitional license agreement.
WGN-TV broadcasts of Chicago Cubs and White Sox games concluded at the end of the season. WGN held the local broadcast television rights of both teams since 1948. The network's final telecasts took place on September 28 (Cubs) and September 29 (White Sox). Effective with the 2020 season, Cubs games will move exclusively to the new Marquee Sports Network, while White Sox games will air full-time on NBC Sports Chicago.

### Radio
#### Local

* The New York Mets moved from iHeartMedia's WOR (710) to Entercom's WCBS (880), returning the team to the fold of the former CBS Radio New York cluster after five years with WOR (the team previously had a decades-long association with WFAN). However, the team's radio network throughout New York State was dissolved before the season, leaving WCBS the only station broadcasting the team's games.

#### National

* ESPN Radio will air its 22nd season of national coverage, including Sunday Night Baseball, Saturday games, Opening Day and holiday games, the All-Star Game, and Home Run Derby, and the entire Major League Baseball postseason.

### Digital

MLB's contract with Facebook Watch has been further downsized, now only consisting of six games (reduced from 25). In addition, the games will no longer be exclusive to the service, and subject to blackout in-market. The league also reached a new digital partnership with the streaming service DAZN, who now airs a daily studio program, ChangeUp, which features live look-ins on games in progress.
In mid-July, MLB and Google announced that 13 games will air exclusively on YouTube, produced by MLB Network.
