Carlos Alcaraz, the defending champion returning from a wrist injury, holds a strong position to reach the semifinals thanks to a favorable bottom-half draw cleared of major threats after Jannik Sinner’s pre-tournament withdrawal with a right knee injury. Alexander Zverev, the top seed, benefits from an open top half and strong recent hard-court results. Ben Shelton, Daniil Medvedev, and emerging Americans like Learner Tien or Frances Tiafoe remain live contenders in their sections, though bracket imbalances and the physical demands of late-summer hard courts favor the top two. Official injury reports and third-round results have already shifted implied probabilities, with Alcaraz and Zverev emerging as the clearest paths to the final four amid ongoing round-of-16 action.
