Strike three or ball four? T-Mobile (NASDAQ: TMUS) today announced that as the official wireless partner of MLB, the Un-carrier is powering the debut of MLB’s automated ball-strike system (ABS) at the major league level for the first time with a private 5G Advanced Network Solution (ANS). The 5G-powered ABS system will be featured during spring training games at Steinbrenner Field in Tampa, Florida, beginning Feb. 21. T-Mobile also announced that it’s bringing back one of its most popular perks — free MLB.TV — for customers starting March 25, just in time for MLB Opening Day.

“At T-Mobile, every sports and entertainment partnership is about pushing the boundaries of innovation with our industry-leading 5G network and delivering more to our customers,” said Mike Katz, President of Marketing, Strategy and Products, T-Mobile. “That’s exactly what we’re doing by powering 5G-enabled ABS in Major League Baseball — demonstrating how our 5G network can support partners like MLB — in addition to giving our customers a front-row seat to all the baseball action this season with the return of free MLB.TV.”
5G-Powered ABS
T-Mobile’s 5G-powered ABS system will be tested for the first time at the major league level following trials over the last two years at select minor league games and at the All-Star Futures Game during MLB All-Star Week. MLB’s ABS system uses high-speed Hawk-Eye cameras set up around the stadium to triangulate the strike zone above home plate for each player. Once the pitch is thrown, T-Mobile’s private 5G ANS transmits pitch data from the ABS system via 5G-connected devices — enabling quick and secure pitch location verification.
A private 5G network provides an ultra-reliable, high-speed and low-latency connection, enabling real-time communication with the ABS system as calls are challenged, pitches are analyzed and decisions are relayed to players and fans.
T-Mobile’s network also powers the 5G-connected devices used for the ABS system, including:
- Laptops MLB officials use to input team lineups to ensure strike zone accuracy for each batter and to relay game and strike zone information to MLB applications.
- Tablets at the ballpark to provide MLB staff and officials with real-time game video for analysis feedback on the strike zone.
Continued 5G Expansion in MLB Stadiums
T-Mobile has been deploying and expanding its industry-leading 5G network across the country at MLB stadiums. It has rolled out private 5G networks at 27 MLB ballparks to date, with plans to be in every U.S. ballpark before the end of 2025.
