NEW YORK (Reuters) -Aryna Sabalenka and Novak Djokovic overcame early tests to reach the U.S. Open second round before the Grand Slam descended into chaos late on Sunday when Daniil Medvedev launched a tirade at the match umpire and fans disrupted his opponent's service game.
New York's famously rowdy fans caused a six-minute delay by refusing to stop jeering and booing midway through Medvedev's 6-3 7-5 6-7(5) 0-6 6-4 defeat by Benjamin Bonzi on Louis Armstrong Stadium.
