Arguing with the umpire is about to get even more fruitless than in the past, at least at Steinbrenner Field, the New York Yankees’ spring training home in Tampa, Florida.

This spring, Major League Baseball (MLB) will test an automated ball-strike (ABS) system for the first time at the major league level. ABS uses T-Mobile’s 5G Advanced Network Solution (ANS), according to the carrier.

“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,” Mike Katz, T-Mobile’s President of Marketing, Strategy and Products, said in a press release.

“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.”

The first use of the system at Steinbrenner Field was slated for February 21.

The system uses Hawk-Eye cameras around the stadium to triangulate the strike zone above each player. After a pitch is thrown, the private ANS system transmits data from via 5G connected devices, T-Mobile said.

T-Mobile’s network also will:

• Transmit team lineups to laptops to ensure strike zone information is correct for each player.
• Relay game and strike zone information to MLB applications.
• Transmit ABS video to MLB staff and officials for real time feedback on the system.

The system has been trialed at minor league games and during the MLB All-Star Futures game during all-star week.

In the same press release, T-Mobile said that it again will offer free MLB.TV on March 25. The carrier said that it is “one of its most popular perks.”
