Overview
- The final ended after about 23 minutes when world No. 1 Jannik Sinner retired, saying he had felt unwell since Sunday.
- Carlos Alcaraz secured his third Masters 1000 trophy of the season after Monte Carlo and Rome, and his eighth overall at this level.
- The result moved Alcaraz’s head-to-head lead over Sinner to 9–5, including 6–2 on hard courts.
- Alcaraz expressed sympathy in his speech and by signing "Sorry Jannik" on a TV camera, while Sinner apologized to fans for retiring.
- Hot, humid conditions were reported in Cincinnati and broadcasters noted illness among players; Sinner is likely to skip the new US Open mixed doubles as he takes a few days to recover for his singles title defense.
