Separately today, Major League Soccer (MLS) announced a three-year deal with Twitter Inc to stream live matches, highlights and other content on the micro-blogging platform.
This will be the first time any major U.S. sports league has agreed to broadcast regular season games exclusively on the social network.
The first game on Facebook Watch will be a matchup between the Philadelphia Phillies and the New York Mets at Citi Field on Wednesday, April 4.
In a continuing effort to become a one stop shop for virtually everything, Facebook has signed an exclusive deal with Major League Baseball to stream 25 afternoon games during the 2018 season, according to Bloomberg. "This is part of the next great leap". It also plans to stream 47 upcoming United States college basketball games from smaller conferences.
With 1.4 billion active daily users, the world's biggest social network is also still growing, in contrast with conventional TV networks that have been losing viewers and advertising.
The analyst added that it's likely the Major League Baseball views this as more of a test than any sort of money-making endeavor, noting that afternoon games on weekdays typically aren't marquee events.
MLB Network will produce the games, "meaning they'll have a broadcast look and feel".
The games will be available to Facebook users in the US on Facebook Watch, the company's video feature, via the MLB Live show page.
It is also the latest salvo in a battle between Facebook, Amazon, Twitter and Yahoo to add more sports content to their online offerings. It previously simulcast Friday night games on Facebook last season. The company did acquire the rights to NFL recaps and highlights, giving the league a way to reach fans on the social media service.
