Defending champion Novak Djokovic has reached the third round of the U.S. Open after his opponent had to stop in the third set of their match with an injury. Djokovic led Laslo Djere 6-4, 6-4, 2-0 on Wednesday night when his Serbian countryman retired. Djere was leading 4-2 in the second set when he appeared to be troubled by pain near his hip and was visited by a trainer later in the set. It was the 90th win at the U.S. Open for Djokovic, allowing him to reach that total at all four Grand Slams. The 24-time major champion will play No. 28 seed Alexei Popyrin on Friday.
