France’s Benjamin Bonzi upset No. 13 Daniil Medvedev of Russia in the final match of Sunday's first-round play at the US Open.

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. All of a sudden, a match that looked like it was destined for a straight-set victory for Bonzi turned into a five-set thriller.

A photographer walking down the court during match point resulted in a chair umpire's ruling that sent Russian player Daniil Medvedev into hysterics.
