He won the Canadian Open earlier and entered Flushing Meadows as one of the biggest hopes for American men’s tennis. He looked solid in the first two rounds before his run was halted in the third round by a shoulder injury sustained during his match with Adrian Mannarino. Shelton retired mid-match, explaining afterwards: "I'm not a guy who would retire if I could continue."The pain in his left shoulder was severe. Shelton said it was the "worst pain I’ve ever felt in my life."Before Shanghai, he withdrew from several tournaments to rest and recover. Despite the disruption, Shelton, during a media appearance, insisted that he only returned to competition when he felt ready (via ATPTour.com): "As any injury, it takes time to recover. I wouldn’t show up to a tournament unless I thought I was ready and that is why I skipped a few, but I should be ready to go now."At the 2025 Shanghai Masters, returning from his US Open setback, Shelton faced David Goffin. Jannik Sinner watched on from the stands as one of his title competitors of the event, in the absence of World No. 1 Carlos Alcaraz, disappointingly bowed out of the event.
