Carlos Alcaraz won the Cincinnati Open title in anticlimactic circumstances as rival Jannik Sinner retired due to illness just 23 minutes into the match.

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."

Carlos Alcaraz will do everything he can to overtake his top rival Jannik Sinner and return to the top of the ATP rankings by the end of this season, which is why he is also giving his best at the Cincinnati Masters 1000 which precedes the US Open (scheduled in New York from August 24 to September 7).
