The world's top two tennis players met again in the Cincinnati Open this week with No. 1 Jannik Sinner facing No. 2 Carlos Alcaraz in their fourth finals matchup of 2025.

Jannik Sinner retired during the Cincinnati Open final against Carlos Alcaraz due to illness. In his winner’s speech, Alcaraz paid a glorious tribute to Sinner.

It was only the third time the Cincinnati Open men’s final ended in a retirement, and the first since 2011 when Novak Djokovic stopped playing in the second set because of a shoulder injury.
