Why Jannik Sinner pulled out of the US Open despite his dominant 2026 season

World number one Jannik Sinner has withdrawn from the US Open tournament. This decision comes after his right knee injury recovery took longer than anticipated. Sinner will remain in Europe to continue his rehabilitation and recovery process. His team is targeting a return during the Asian swing later this season. This withdrawal marks his first Grand Slam absence since his 2019 debut.
