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.

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

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.
