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.

Daniil Medvedev was called out by his US Open first-round opponent Benjamin Bonzi after the Russian's third set rant.

It took a few extra hours, but Benjamin Bonzi pulled off the upset. After nearly blowing a two-sets-to-love lead, which was highlighted by a photographer inadvertently interrupting play with Bonzi serving for the match in the third set against No. 13 seed Daniil Medvedev, the Frenchman hung on in a dramatic fifth set.
