Not yet. I can't even find a story where Sinclair/Bally is even negotiating with the major streaming services. According to CordCuttersNews, the Bally Sports App launch release claims they have a soft 2022 rollout of direct-to-consumer service planned because they want to hook live betting to it -- and my guess is they don't have the technology in place to do it right (or at all).
AT&T TV claims to carry Bally Sports South, but I'm not paying $85/month to switch. Of course, it sucks that the entire southeast is considered the Braves market by MLB.TV, so that's another dead end.
Perhaps they might have thought this out a little better?
