Then in the final match of a first opening Sunday in New York, Daniil Medvedev (13) was dumped out 6-3, 7-5, 6-7 (5), 0-6, 6-4 by Benjamin Bonzi — who had looked set to win in straight sets until a photographer entered the court between his serves on match point.

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.

At Wimbledon in 2017, Medvedev was fined after emptying his wallet and throwing coins at umpire Mariana Alves following a five-set loss to Belgium's Ruben Bemelmans. He disputed a series of controversial calls and said after the match "it was very hot out there" and couldn't remember if he'd asked for Alves' removal.

Daniil Medvedev should feel able to open up emotionally - if he wants to - after his extraordinary US Open outburst, says close friend Andrey Rublev.
