Facebook will stream 25 Major League Baseball games during the 2018 season.
MLB Network will produce the broadcasted games, which primarily take place on weekday afternoons, beginning with an April 4 Philadelphia Phillies-at-New York Mets contest and an April 11 meeting between the Milwaukee Brewers and St. Louis Cardinals.
The league-owned channel was immediately added to YouTube TV's lineup, while MLB.tv - the league's long-running streaming service for live games - will eventually be available to YouTube TV subscribers for an additional fee.
The games that will be broadcast on Facebook will all be afternoon games, primarily on Wednesdays. The game will start at 1:10 p.m. EST.
The Royals' April 18 game at Toronto won't be shown on Fox Sports Kansas City as planned.
The broadcasts will be produced by MLB Network for Facebook but will include social features that are specific to the platform. Worldwide audiences can watch the games directly on MLB's Facebook page.
It's the first time a major USA league has agreed to show regular season games exclusively on Facebook, which has been building a portfolio of live sports.
Games broadcast on Facebook will also provide users with the flexibility to watch on any screen.
"We're excited to extend our partnership with Major League Baseball to make Facebook Watch a home for exclusive, live games every week this season", said Facebook head of global sports partnerships Dan Reed.
"It is a major creative step forward in serving our diverse, passionate community of fans, who will enjoy a uniquely interactive experience watching our games on Facebook each week", Petitti said. For Facebook, however, the rights allow for experimentation with things like social integration and graphics during the broadcast, enhancements popular with younger viewers drawn to digital platforms.
Facebook has loaded up on live sports content over the a year ago as a way to drive more video viewers to its platform.
