Some are misunderstanding what Extra Innings is, and what your RSN is. Two completely different things. If you do not subscribe to a package that has your RSN you will not get your local team when they are playing, wherever they are playing. The exception is when it's on Fox, or sometimes ESPN, or if you have a local channel that still carries some games. But in general no RSN, no game.
Extra Innings is ONLY to be able to get out of market games. Anytime your team is playing that is not an out of market game, doesn't matter where they play. Extra innings is prohibited from showing you your local team, because the RSN has that exclusively. (Other than Fox, ESPN etc,... occasionally) So you are getting everything in the Extra Innings package, regardless of what level you are at.
