If you're a T-Mobile customer (or are considering the deal I posted yesterday), this is a great deal. Read on for more details ...
HERE is a link to the details from T-Mobile. (Hat tip to FatWallet.)
It is unclear if you must remain a T-Mobile subscriber throughout the entire MLB season to keep this benefit, but I'd guess not. It sounds like you just need to be a subscriber during the April 3-10 sign-up window. The, once you have the MLB.tv account, you should be able to watch on whatever network or device you'd like, including TV streaming devices like Roku or Apple TV.
For baseball fans (like me!), definitely a nice T-Mobile benefit.
