Jannik Sinner spent four hours at a Milan clinic for a comprehensive medical examination before returning to competition. The world number one arrived at the Physioclinic in Milan at eight in the morning with four members of his team, where he was seen by Dr. Piero Volpi, his trusted physician.
Why such a lengthy visit
The Italian has not played a competitive match since defending his Wimbledon title for the second consecutive year. He chose to skip the Canadian Open in Montreal to prioritize physical recovery, and this medical visit comes amid speculation about his knee. His team insists the examination was purely precautionary, with no indication of any serious physical issue. Sinner left the clinic smiling and took time to sign autographs for fans waiting outside the building.
The road to the US Open
The world number one is expected to fly to the United States on Sunday, August 9, to prepare for the Cincinnati Masters 1000, his only official tournament before the US Open begins on August 30. Cincinnati represents a crucial step for Sinner, who has not played an official match in several weeks. He views the North American hard-court swing as the decisive phase of his season, particularly since hard courts remain historically his most productive surface.
Three favorites under the microscope
With Carlos Alcaraz out of Cincinnati due to his elbow injury and Jack Draper struggling physically after his second-round exit in Montreal, Sinner completes a trio of favorites whose fitness is raising concerns ahead of the final Grand Slam of the year. The North American swing, usually the hunting ground for the tour's top names, looks set for an uncertain ride. Alexander Zverev, eliminated in the third round in Montreal by Tallon Griekspoor, could capitalize if the absences are confirmed.
Sinner remains firmly installed at the top of the ATP rankings. His 2026 season is already defined by a second consecutive Wimbledon title and a strong record against the top 10. His opening match in Cincinnati will be closely watched across the entire tour.
