T-Mobile Tuesdays has something good for baseball fans starting April 4.

T-Mobile is into doing nice things for its customers recently. The company has announced that it is giving away a free year of MLB.tv baseball streaming to all of its users, including those on older plans and prepaid service.

A regular season costs $112.99 a year, with MLB at Bat, which includes mobile phone access, an additional $19.99, so Major League Baseball is likely hoping that this turns into some revenue-positive conversions in the 2018 season. At Bat is included in the promotion.

T-Mobile says that the promo is not a part of its T-Mobile Tuesdays campaign, where it gives something nice away every week. This one you'll need to find by heading to the Groupon link. The promo begins April 4 to celebrate the official return of baseball in the U.S. (and Canada — don't forget the Blue Jays!)

Customers will only have over a day to sign up for the promotion; it ends at 4:59am ET on April 5. Once signed up, customers will need to sign into the MLB.tv app or website before 4:59am ET on April 11, so there isn't much time to take advantage of the promo. And according to the rules, the free access will expire on February 28, 2018.

T-Mobile Tuesday 'Thank You' gifts on April 4th include a free VUDU baseball movie rental, a $2 DUNKIN' PROMO CARD, and 30% off Groupon Local (up to a $40 value).
