Alex de Minaur Advances US Open Fourth Round Only Australian Remaining

Alex de Minaur advanced to the fourth round of the US Open for the fifth time after German Daniel Altmaier retired injured while trailing in their match. Altmaier, who had endured a grueling schedule including a marathon victory over Stefanos Tsitsipas, succumbed to a thigh injury after two medical timeouts, allowing the Australian eighth seed to secure the win. De Minaur, known for his consistency, has now reached the last 16 in eight of the past nine Grand Slams and will face Swiss qualifier Leandro Riedi, ranked No. 435, with a chance to make the quarterfinals for the third time. He remains the last Australian contender in singles after Daria Kasatkina lost a hard-fought three-set match to two-time US Open champion Naomi Osaka, who will next face Coco Gauff in a highly anticipated fourth-round meeting. This win also bolsters de Minaur’s prospects of qualifying for the season-ending championships in Turin. The New York crowd has embraced Osaka, who has returned to fourth-round contention at a major for the first time since 2021.
