Earlier last week, World No. 2 Carlos Alcaraz clinched the 2025 Cincinnati Open title on Monday as Sinner retired from the game after playing five games of the first set. In the fourth final meeting of the 2025 season, the typically steady Sinner dropped his opening service game at love. Alcaraz went on to win four more games in a row before the Italian called the trainer during the changeover. Minutes later, the world's No. 1 player retired from the match. The two players, who have relished their rivalry, exchanged words, with Alcaraz putting his arm around his opponent and looking visibly concerned for Sinner's health, according to Olympics.com. Coming into the final, Sinner, who celebrated his 24th birthday during the tournament, had not dropped a set.
