MLBTV Subscription Link to MLB Extra Innings.

Same.  I have an existing MLB TV Account, and i just learned that you can get Extra Innings with it.  My MLB TV account and my Comcast Xfinity account are associated with different emails.  How can i activate Extra Innings on my TV?

Good morning, @arcook01! Thank you for reaching out recently with your question about MLB TV and Extra Innings! 

MLB EXTRA INNINGS includes access to https://comca.st/3tHWBdL online and the MLB app this season.

MLB EXTRA INNINGS customers can simply follow the steps below to activate the https://comca.st/3tHWBdL Premium account and start watching:

1. Go to https://comca.st/3QwkMWn.
2. Select Xfinity as your provider.
3. Sign in using your Xfinity ID and password.
4. Create a new https://comca.st/3b8VtJZ account or sign in with your existing account to link your Xfinity ID and password with https://comca.st/3tHWBdL.

That said, I do not see the reverse as an option, to link an existing MLB TV subscription to Extra Innings, since Extra Innings is a premium pay service. If the steps above work to link the two for you, please feel free to share in our Community here, so that other amazing customers such as yourself can also benefit! -Macey
