Overview
- Organizers and Sinner confirmed the withdrawal on Sunday, August 9, 2026, after the world No. 1 reported persistent right-knee discomfort.
- Medical staff describe the issue as an overload-related inflammation rather than an acute structural injury and Sinner has had multiple checks at J|Medical in Turin and a control visit at Physioclinic in Milan.
- Sinner will continue targeted physiotherapy and shockwave treatment in Italy while his team focuses on getting him fit for the US Open rather than risking play in Cincinnati.
- Skipping Cincinnati costs him 650 ATP points and leaves him without competitive hard-court matches since his Wimbledon final on July 12, reducing match practice before New York.
- The decision reflects broader load management after an intense season of consecutive Masters 1000 events and raises questions about how Sinner will balance recovery, match sharpness, and the season-end rankings race.
