Benjamin Bonzi stunned former champion Daniil Medvedev in the opening round of the US Open on Sunday night, prevailing 6-3, 7-5, 6-7(5), 0-6, 6-4 in a match that finished shortly after 1 a.m. in New York. The French world No. 51 has now beaten the No. 13 seed in all three of their Grand Slam meetings, each time in the first round. The contest turned chaotic late in the third set when a photographer walked onto Louis Armstrong Stadium as Bonzi prepared a second serve while holding match point. Chair umpire Greg Allensworth ruled the point replayed with a first serve, triggering an angry tirade from Medvedev—“Are you a man? Why are you shaking?”—and a six-minute delay amid sustained boos. Tournament officials said the photographer was escorted out and had his credential revoked. Medvedev harnessed the uproar to claw back the next two sets, but Bonzi regrouped in the decider, breaking twice and sealing victory with a backhand winner. The 2021 champion smashed his racket at courtside after the defeat and left facing the prospect of further sanctions for his outburst, according to tournament organisers. “It was crazy—thanks to everyone who was booing,” Bonzi told reporters. Medvedev insisted his anger was directed at the umpire’s decision rather than the photographer, saying, “Every time there’s noise between serves, you don’t get a first serve.” The loss makes Medvedev the first past champion to exit this year’s tournament.
