Sinner Withdraws From Cincinnati: Right Knee Sidelines World No. 1

Jannik Sinner has withdrawn from the Cincinnati Masters 1000, scheduled for August 13-23. The announcement came on Sunday, August 9:

"My right knee is bothering me, and despite the hard work done with my medical team, I have to accept that I'm not ready to compete yet."

The world No. 1 hasn't played an official match since July 12, the day of the Wimbledon final he won against Alexander Zverev 6-7(7-9), 7-6(7-2), 6-3, 6-4, his fifth Grand Slam title and second straight on the London grass. He had already pulled his name from the Montreal entry list in late July, a decision that ended his streak of six straight Masters 1000 titles. Withdrawing from Ohio also costs him the points he earned there in 2025, when he retired in the final after a handful of games against Carlos Alcaraz.

Cincinnati is left without the top two players in the rankings. Carlos Alcaraz had announced his withdrawal a few days earlier because of the wrist injury that has kept him out since April, so the No. 1 seed now passes to Zverev.

Sinner's focus now shifts entirely to the US Open, which starts August 30. He'll arrive without having played a single match on American hard courts, trading that for three full weeks of work on the knee. His cushion in the rankings lets him afford it: with Alcaraz sidelined since spring, the No. 1 spot isn't in question in New York.
