Daniil Medvedev's match was delayed more than six minutes between points Sunday night after a photographer entered the court on match point, and the 2021 US Open champion became enraged by the chair umpire's decision to award his opponent a first serve.

The first-round match between No. 13 seed Daniil Medvedev and Benjamin Bonzi Sunday night at the US Open turned chaotic when, of all things, a photographer prematurely stepped onto the court as Bonzi served for the match.
