Daniil Medvedev is out of the US Open after a remarkable defeat by Benjamin Bonzi, where a photographer walking on to the court changed the course of the match.

Daniil Medvedev was two sets and match point down to Frenchman Benjamin Bonzi on Monday (AEST), only for a photographer to bizarrely sneak onto Louis Armstrong Stadium and change the course of the match.
