Facebook and the MLB announced a new partnership today that will see 20 regular season baseball games live-streamed on Facebook this season, according to TechCrunch.

Games will air weekly on the MLB Facebook page

The games will air weekly on the MLB Facebook page, starting tomorrow night with the Rockies vs. Reds game at 7:10PM ET. According to TechCrunch, the broadcast will be sourced from a local broadcaster from one of the participating teams, without local blackouts. Future Friday night games for streaming will be announced soon.

This is another big partnership for Facebook’s live streaming ambitions, after the company recently announced a partnership with the MLS to stream live soccer matches. And Facebook isn’t the only one trying to build out live sports streams. Twitter previously bought the rights to air Thursday Night Football games with the NFL last season, which Amazon has now picked for the coming season to offer to its Prime customers. Twitter still has some NFL rights too, for other, live content that isn’t streaming games, which still illustrates how important sports streaming rights are getting for social networks.
