The US Open descended into chaos on Sunday when a photographer came onto the court as Daniil Medvedev faced match point, bringing the first-round match to a standstill and sparking a spectacular meltdown from the Russian.

Former champion Medvedev was eventually knocked out 6-3 7-5 6-7(5) 0-6 6-4 by Frenchman Benjamin Bonzi, who threatened to walk off the court at one point and called for the Russian to be disqualified.
