In the 2026 Italian Open semifinal held in Rome, Jannik Sinner, ranked World No. 1, encountered significant physical struggles during his match against Daniil Medvedev. After a strong start, winning the first set 6-2, Sinner appeared fatigued in the second set, even displaying signs of distress, including a moment where he seemed to vomit on the court. His performance raised concerns, especially as he had previously shown signs of fatigue during his quarterfinal match against Andrey Rublev, where his first-serve percentage plummeted to 39%. Commentators, including Jamie Murray, expressed surprise that Sinner did not request a medical timeout despite his evident struggles. Murray noted, “It is weird for me that he doesn’t take the physio or the doctor, there’s clearly something wrong with him.” Amidst these challenges, Sinner received support from his girlfriend, Laila Hasanovic, who was seen in the stands alongside his family. Despite the mounting concerns, Sinner attempted to downplay his condition, stating, “I’m going to be all right. It’s normal that one day in the tournament you are slightly tired.”
