T-Mobile, the official wireless sponsor of Major League Baseball, is handing out free MLB At Bat Premium access to its customers for the third year in a row.

To take advantage of this offer you’ll need to fire up the MLB.com At Bat app for iOS or Android while connected to the T-Mobile network on or after May 1st. The promo will not unlock if you’re on Wi-Fi the first time you open the app, even if you’re a T-Mobile customer. However, after you successfully redeem the offer you’ll be able to access the app over Wi-Fi without any problems.

The subscription is only good for the 2015 season, which is a savings of $19.99. With At Bat Premium you get:

  • Stream the MLB.TV Game of the Day (blackout restrictions apply)
  • Track every pitch
  • Watch in-game highlights
  • Access live look-ins on key plays

This plan won’t cover you for live video streaming of every game. For that you’ll need to upgrade to an MLB.TV subscription. expand full story
