Defending champion Novak Djokovic achieved his 90th win at the US Open on Wednesday, advancing past compatriot Laslo Djere, who retired during their second-round match. Djokovic was leading 6-4, 6-4, 2-0 when Djere decided to call it quits due to injury.Djere, ranked 109th in the world, had previously challenged Djokovic, pushing him to five sets in the same tournament last year. This time, he required a medical timeout after the second set to address an injury. Djokovic himself had to receive treatment for what appeared to be a side strain after winning the first set, but he continued to play effectively.With this victory, Djokovic became the only male player to win 90 matches at all four Grand Slam tournaments. Reflecting on the match, Djokovic expressed disappointment over Djere's retirement, noting that he had been performing well and was leading in the second set. "Laslo had an injury which took him off the tour for some time and he's been struggling to come back," Djokovic said. He acknowledged Djere's capabilities, stating that the second set should have gone in Djere's favor.Looking ahead, Djokovic is set to face Alexei Popyrin from Australia in the next round, having previously defeated him at both the Australian Open and Wimbledon earlier this year. Djokovic’s quest for a record 25th Grand Slam title continues as he advances in the tournament.
