On the ninth hole of the final round of the CJ Cup Byron Nelson at TPC Craig Ranch earlier this month, Wyndham Clark found himself in an extended rules debate after his tee shot picked up mud in the fairway and questions arose over whether he was entitled to relief from standing water. The ruling process, which included a failed appeal, stretched on for several minutes as Clark consulted officials about the situation.

“I’m at Craig Ranch and was literally 50 feet from this. I could have binge watched a season of Landman in the time this took,” one spectator joked on X.

Rules deliberations that drag on have become a growing frustration for players waiting on the group ahead of them and spectators annoyed by how long action takes to resume. T-Mobile and the USGA are hoping to smooth that out as part of a new multiyear partnership that will integrate the wireless carrier deeper into championship operations at the U.S. Open and U.S. Women’s Open.

The Bellevue, Washington-based wireless carrier has been steadily increasing its investment in golf over the past several years, including through its existing partnership with the PGA Championship. The deal integrates the provider into multiple layers of championship operations, from officiating and real-time media workflows to ticket scanning and point-of-sale systems at the national opens.

A notable component is a collaboration on the USGA’s first mobile Rules Review system, which will allow officials to access video footage and communicate in real time from anywhere on the course. The partnership also uses network slicing for rapid photo uploads by the USGA content team, along with enhanced connectivity for entry gates and concessions across sprawling championship venues.

T-Mobile said the system was developed collaboratively with the USGA after conversations around officiating pain points and the logistical challenges of reviewing rulings across massive championship properties.

“Across all of our sports partnerships, we really want our network and our technology to be embedded in the sport, in the moments—not just about the signage,” Amy Azzi, T-Mobile’s vice president of sponsorship and events, said.

She pointed to T-Mobile’s role supporting Major League Baseball’s automated balls-and-strikes challenge system that rolled out this season as another example of the company integrating its technology directly into live game operations rather than dialing into traditional sponsorship visibility.

Azzi said the company expects the rules review system to reduce downtime during rulings, noting that officials often lose time locating monitors and establishing connections before reviewing footage. “This will go much quicker,” Azzi said.

Anthony Santora, managing director of IT at the USGA, explained that the organization’s rules officials often operate across “hundreds of acres” while making real-time decisions as play unfolds around them.

“The real benefit here is behind the scenes: knowing right away when support is needed, getting a referee to the right place and allowing the Rules team to communicate clearly across the property,” Santora said.

“T-Mobile’s solution gives us the reliable connectivity to do that without losing time to coverage gaps or dead zones. And in those moments when video can help support a ruling, it also gives us a better way to access and share that information. All of that helps rulings happen more efficiently, which benefits players, referees and fans following the championship.”
