I think the games that Peacock shows on Sunday are exclusive, but I’m not sure. At least in the Detroit area people can watch this game on their Fox affiliate.
Well this broadcast is on FOX and I couldn’t get it through YouTube TV - only the Dodgers, of course - but the Internet lied when I asked if I could watch it on MLB TV and the “Internet“ solemnly informed me that I could not watch it live and it would only be available 90 minutes after the completion of the game. But here it is on mlb.tv.
