What happened to Fox Sports Pittsburgh? I just switched back to directv and can't find it. Anyone know what channel it is or if they don't carry it anymore?

I could find a channel called ROOT Pittsburgh that sounds like it is about the same thing. Does anyone have this? Is it any good? I don't get it now but would add it if it is worth it.

Also I know some areas have Comcast Sportsnet but didn't see one for Pittsburgh. Is there one of those too?

Thank you in advance anyone that is able to answer these questions for me.
