It’s almost time for T-Mobile customers to claim their free year of MLB.TV

T-Mobile’s annual deal for baseball fans is back. From Tuesday through Sunday, the carrier’s customers can claim a free yearlong subscription to MLB.TV for live and on-demand streaming access to the entire Major League Baseball season.

This is the ninth straight year T-Mobile has offered the deal, which the companies have extended through 2028. MLB.TV lets you watch all out-of-market regular-season games and select Spring Training games. (Unfortunately, blackout restrictions, universally loathed by everyone not profiting from them, apply to in-market games.) They stream in HD, and the service supports DVR and in-game playback controls.

The streaming package usually costs $150 for the season or $30 per month, so this is a nice perk for baseball fans. You can claim the offer in the T Life (formerly T-Mobile Tuesdays) app (iOS and Android) from tomorrow through Sunday only, so don’t forget to claim it during that short window.

As a promotional gimmick to help plug the deal, T-Mobile is introducing a “Secret Baseball Button.” The Bluetooth device connects to your computer and can be set to “discreetly switch from baseball to ‘work’ with the literal click of a button.” (It’s the same idea as the March Madness Boss Button, only in physical form.) If you care about such things, you can enter a sweepstakes for a chance to win one.
