A devastated Daniil Medvedev was knocked out of the US Open after a meltdown sparked by a photographer walking on to the court during his first-round defeat by Benjamin Bonzi.
Medvedev has produced some extraordinary moments at Flushing Meadows over the years – but what happened on the 2021 champion's way to another humbling defeat was perhaps the most incredible.
As the Russian faced match point at 5-4 in the third set, the cameraman walked on to the playing surface between his French opponent Bonzi's first and second serve.
Cue bedlam as the incident - and Medvedev's reaction - changed the course of the match.
