NEW YORK — There was bedlam at the U.S. Open Sunday night, when Daniil Medvedev’s 6-3, 7-5, 6-7 (5), 0-6, 6-4 defeat to Benjamin Bonzi was delayed for six minutes after a photographer prematurely entered the court.

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.

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.
