T-Mobile became the official wireless sponsor of Major League Baseball on Tuesday.

As part of the multi-year, multi-million dollar partnership, T-Mobile will provide MLB with a new On-Field Communication System, including a wireless voice system connecting managers in select MLB dugouts to coaches in bullpens. This dugout-to-bullpen system will start to roll out this season.

"We look forward to working with Major League Baseball and are excited they have chosen T-Mobile's technology to power a new, in-game communication system at ballparks across the country," said Mike Sievert, chief marketing officer, T-Mobile USA. "Unlike a typical sponsorship, we're approaching this partnership as a collaboration in which T-Mobile, MLB and MLBAM will work together to evolve the game with exciting new technology innovation enhancing the experience for customers and fans."

In collaboration with Major League Baseball Advanced Media, T-Mobile plans to further enhance and broaden network coverage and connectivity for fans in MLB ballparks. Additionally, they plan to enrich the digital experience on its smartphones and tablets, create custom, compelling content exclusively for its customers, as well as develop promotional opportunities and unique offers for MLB.com content.

"Baseball is America's number one digitally consumed sport and today's baseball fan is technologically savvy and data hungry, which makes this partnership a great opportunity for not only baseball enthusiasts, but millions of T-Mobile customers," added Sievert.
