World number one Jannik Sinner has pulled out of the Cincinnati Open with a right knee injury, tournament organisers said on Sunday, handing the Italian a blow in his preparations for this month’s U.S. Open.
The 24-year-old Italian, who claimed his fifth Grand Slam title at Wimbledon last month, had also pulled out of the Canadian Open, a key warm-up event for the U.S. Open.
