India, Aug. 9 -- World No. 1 Jannik Sinner has withdrawn from the Cincinnati Open after picking up a right knee injury, dealing a setback to his preparations for the US Open. The Italian was expected to begin his North American hard-court campaign at the Masters 1000 event, which starts on August 13, but will now miss the tournament as he focuses on his recovery.

Sinner had already skipped the National Bank Open in Montreal and has not competed since winning Wimbledon in July. The 2024 Cincinnati Open champion was hoping to return to action ahead of the US Open, but the latest knee issue has forced him to delay his comeback.
