Birthday and achievements
World No. 1 Jannik Sinner celebrated his 25th birthday at home with family in a relaxed setting. His career already boasts five Grand Slam titles, two ATP Finals, two Davis Cups, and 30 overall trophies. From tomorrow, he will mark his 85th week at the top of the rankings, a milestone that underscores his dominance in men’s tennis.
Knee injury and preparation
Sinner’s journey to the US Open has been complicated by a right knee injury that forced him to skip the Cincinnati Masters. Under the guidance of physiotherapist Claudio Melegati, he has been undergoing daily physiotherapy sessions at J Medical in Turin, even continuing treatment on August 15 before pausing for his birthday.
Upcoming schedule
The plan for the coming week includes completing his knee therapy and reviewing progress with his medical team to ensure no detail is overlooked before traveling to the United States. The US Open begins in 14 days, with Sinner expected to debut on August 30 or 31. For the second consecutive time, he will enter a Grand Slam without playing preparatory tournaments, a scenario that already occurred at Wimbledon earlier this summer.
Context and outlook
Sinner’s decision to prioritize recovery reflects his determination to arrive in New York fully fit. His absence from warm-up events may raise questions, but his track record shows he can still perform at the highest level without prior competition. Fans and analysts will closely watch how his knee responds as he targets another deep run at a Major.
