Sinner retired with apparent illness in the first set of Monday's Cincinnati Open final against Alcaraz after digging a 5-0 deficit. Sinner remained on the court for the trophy ceremony and addressed his condition while speaking with the crowd. He didn't offer specifics, but said that he "didn't feel great."

The five-time Major champion reflected on a key moment from earlier this summer - his first loss in a Major final at Wimbledon to Jannik Sinner. After winning the first five Major finals, Carlos ended on the losing side for the first time.

The Cincinnati Open men's final Aug. 18 will feature the fourth championship meeting this year between top players Jannik Sinner and Carlos Alcaraz.
