See that's what I'm worried about. I need to find a streaming service with NESN on it so I can drop the MLB internet package and still see Red Sox games.
Or a friend that has a subscription with one of the television providers supported by the Fox Sports Go app. We use it on our Roku.
FOX Sports live games and streaming video
You can log in with that, and watch the games that way.
Also, if you know someone with an AT&T U-VERSE subscription, and you are in an area that offers NESN National in their cable package (NESN National), you can sign in with their login and watch Red Sox games.
With this method, you can stream it on your mobile device, then if you have a Roku, cast it to the Roku.
