Tennis star Jannik Sinner has withdrawn from the Cincinnati Open final against Carlos Alcaraz, sparking significant concerns regarding his participation in the upcoming US Open. Sinner, the world No. 1 and Wimbledon champion, retired from the match after just 23 minutes of play, with Alcaraz holding a dominant 5-0 lead in the first set.

Sinner expressed severe discomfort, telling trainers and a tournament official, "I cannot move - I feel like I can collapse." He apologized to fans for the early retirement, stating, "I tried, but I can't. I'm sorry for the fans." Although he was receiving treatment on his leg when he pulled out, the umpire announced his retirement was due to illness rather than an injury. Sinner later explained that he had been feeling unwell since the previous day and his condition had worsened overnight, making it impossible to continue the match.

The emotional 24-year-old was seen sitting down as Alcaraz approached to console him, a gesture of sportsmanship that saw the Spaniard write "sorry Jannik" on a TV camera and call Sinner a "true champion," predicting his return to the court "better, even stronger."

Speaking after receiving his runner-up trophy, Sinner reiterated his apologies to the disappointed fans and thanked his team for their understanding. He also congratulated Carlos Alcaraz on securing his eighth Masters title, acknowledging the impressive season Alcaraz is having. This win provided Alcaraz a form of revenge for their Wimbledon final encounter.

The premature exit has cast a shadow over Sinner's US Open prospects. He is currently scheduled to play in the mixed doubles event alongside Kateřina Siniaková against Alexander Zverev and Belinda Bencic in the round of 16. The main draw for the men's singles US Open is set to commence shortly, leaving uncertainty about Sinner's readiness for the major tournament following this challenging, hot tournament.
