Sinner’s Withdrawal and Impact
Jannik Sinner, the world No. 1, has announced his withdrawal from the 2026 US Open. This decision means he will not be able to defend his top ranking at the season’s final Grand Slam. Sinner cited ongoing issues with his right knee as the reason for his absence, stating that he and his team made a “difficult decision” after recent practice sessions in Monte Carlo indicated he still requires more recovery time before returning to competitive play.
The Italian expressed his disappointment, noting that New York holds a special significance for him and he had anticipated playing again before the crowds at Flushing Meadows. Sinner reached the final of last year’s US Open, where he was defeated by Carlos Alcaraz in a match that garnered significant attention in recent tennis history.
This withdrawal marks a shift for Sinner, who had a successful season up to this point. He successfully defended his Wimbledon title earlier in the summer, defeating Novak Djokovic in the semifinals before securing the championship. The knee injury interrupts a period where Sinner had been a dominant force in tennis.
Tournament Dynamics Shift
Sinner’s absence significantly alters the landscape of the US Open tournament. With the top seed no longer in the draw, other contenders such as Carlos Alcaraz, Alexander Zverev, and Novak Djokovic may find a clearer path to the title. Additionally, American players like Ben Shelton and Taylor Fritz, who was last year’s runner-up, are now seen as more serious contenders.
Carlos Alcaraz is also making his return to Grand Slam play at this event, having been recovering from a lengthy wrist injury. The singles main draws for the US Open are scheduled to begin on August 30. This year’s singles champions are set to receive $5.5 million.
Sinner had previously withdrawn from the Cincinnati Open earlier this week due to the same knee issue. He has been undergoing medical evaluations in Milan and Turin throughout August to assess the extent of the injury. His withdrawal means that French Open champion Alexander Zverev will now be the No. 1 seed, and defending champion Alcaraz will be the No. 2 seed.
The absence of Sinner means that he and Alcaraz will not meet in a major final in 2026, despite having faced each other in three consecutive major finals in 2025. This situation provides Alcaraz with an opportunity to potentially extend his 7-5 lead over Sinner in major titles, though Alcaraz has not played a competitive match since April 14.
For Sinner, the focus is now entirely on his recovery, with his attention likely turning towards the next season and the opportunity to regain his form after missing the US Open.

Senior tennis writer Matthew Futterman noted that the situation has reversed from a few weeks prior, when it appeared Alcaraz might miss the US Open and Sinner, considered a top hard-court player, could have a straightforward path to a sixth Grand Slam title. Now, Alcaraz is confirmed to play, with his wrist theoretically healed after four months without competitive tennis, while Sinner is out due to his knee injury.
This injury has limited Sinner to seven matches since the French Open, all played during his Wimbledon victory. The 2026 Grand Slam season will conclude without a single final between Sinner and Alcaraz.
