Overview

• Sinner retired from the Cincinnati final against Carlos Alcaraz due to a virus, his coach Darren Cahill confirmed.
• He withdrew from the US Open mixed doubles, but has been resting in New York and is slated to hit on Arthur Ashe on Thursday if progress holds.
• Medical guidance cited in reports says mild viral illnesses can clear in three to five days, though tougher cases may take one to two weeks or longer.
• Alexander Zverev’s quick return to court after dealing with a similar bug has been noted as a potentially encouraging precedent.
• Pundits including Mats Wilander and Ivan Ljubicic caution that a longer recovery could leave Sinner vulnerable in early rounds despite his strong hard‑court form.
