Daniil Medvedev's match was delayed nearly seven minutes after a photographer entered the court on match point with the former US Open champion enraged by the chair umpire's decision to award his opponent a first serve.

With Bonzi serving for the match - leading 6-3 7-5 5-4 - a photographer entered the court.

"Wait please, not now," chair umpire Greg Allensworth shouted. "Get off the court, please" before announcing that Bonzi would get another first serve because of the delay.

"First serve. Ladies and gentlemen, because of the delay caused by an onside interference, first serve has been granted," Allensworth announced.

A furious Medvedev then approached the chair to complain about the decision.

"Are you a man? Are you a man? Why are you shaking? What's wrong, huh? Guys, he wants to leave. He gets paid by the match not by the hour," Medvedev said into the camera that was positioned next to the chair umpire.

Medvedev kept encouraging the loud boos on Armstrong, which eventually lasted so long that he then tried to get fans to quiet down so Bonzi could serve.

When Bonzi finally did, he double faulted. Medvedev won the game and then took the set in a tie-breaker to prolong the match.

However, the Frenchman eventually sealed a 6-3 7-5 6-7 (5-7) 0-6 6-4 victory with a visibly emotional Medvedev disintegrating his racket against his chair as Bonzi celebrated.

The United States Tennis Association [USTA] later confirmed in a statement: "The photographer was escorted from the court by US Open security. His credential has been revoked for the 2025 US Open."
