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 iPhone, iPad and Apple TV 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 part of its T-Mobile Tuesdays campaign, where it gives something nice away every week. The promo begins April 4 to celebrate the official return of baseball in the U.S. (and Canada — don't forget the Blue Jays!)

T-Mobile Tuesdays free stuff (including MLB.TV Premium) is available to all customers on a T-Mobile branded monthly rate plan, including consumer and business, postpaid and prepaid plans. Every line can participate.

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.

Additional 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).
