Doubts grow regarding Sinner: reports from Italy suggest there may be a problem with his knee
The presence of the world number one in Cincinnati could be in jeopardy: according to Corriere della Sera, Jannik's team does not rule out going directly to the US Open.
Jannik Sinner is becoming one of the big names in the world of tennis in recent hours... and that’s despite not competing in Canada. The latest news concerning the Italian has generated a lot of discussion and refers to his physical condition, with possible last-minute discomfort leading to tests that were not planned. Contradictory news, hidden reports, and a slight sense of skepticism surround a case that has seen a development in recent hours, a development reported by Corriere della Sera, which states that the tests Jannik underwent in Milan a couple of days ago were not part of the routine.
It was the news that started it all, quickly denied by some sectors in the transalpine country, but it has gained traction again in recent hours. Sinner went to the Polyclinic in Milan to undergo checks led by Dr. Gianluca Melegati, focusing on possible discomfort in his right knee that occurred upon his return to training after his vacation. With the Wimbledon title under his belt, Jannik maximized his rest time and, once back on the courts, the timing and urgency of these tests raised some alarms. Those alarms were quickly deactivated... but they could ultimately indicate minor issues.
Sinner's presence in Cincinnati may be in doubt: here's what is known
It was the Corriere della Sera that, in an article published in its Sunday edition, claims that the tests Jannik underwent were not part of the established plan, being checks that the Italian requested to address a minor discomfort in his right knee. The results seem to have been good, but there are doubts about the world number one’s upcoming roadmap: there is a possibility that he may undergo a second test in the coming days (which would give us an idea of the level of concern this discomfort may cause), and Sinner's team is even considering not attending the Masters 1000 in Cincinnati, scheduled to start on August 13 (in just 7 days).
There seems to be some discomfort in the knee, maybe new checks in Milano before leaving for the USA.
Let’s wait and hope for the best. 🤞🦊

Is the US Open in jeopardy? This is a question that is directly addressed from the Mediterranean country without any doubt: no. The minor discomfort Jannik may have felt in his knee is not strong enough to lead to more catastrophic scenarios, and the number one priority for the player from San Candido is to reclaim the crown in Flushing Meadows. Moreover, the doubts regarding attending Cincinnati stem from the search for the best physical condition possible to compete in New York, prioritizing the assault on the crown above all else. However, what seemed like a smooth transition to the North American hard courts appears to have encountered a slight bump... which we will see how far it can go in the coming days.
