Overview

• Jannik Sinner defeated Gabriel Diallo 6-2, 7-6(6) to secure a spot in the fourth round and will face Adrian Mannarino next.
• Darren Cahill and Simone Vagnozzi were confirmed on site in Cincinnati as Cahill emphasized increased first-serve speed and placement in Sinner’s game plan.
• Carlos Alcaraz beat Hamad Medjedovic 6-4, 6-4 for his 50th win of the season and became the first player since Djokovic to record four straight 50-win campaigns, setting up a showdown with Luca Nardi.
• Matches this week have been challenged by sweltering heat, a 75-minute power outage that delayed Taylor Fritz’s match and a fire alarm that briefly interrupted Sinner’s contest.
• Alcaraz holds roughly a 1,540-point advantage over Sinner in the ATP Race to Turin as both defend heavy points at Cincinnati and prepare for the US Open.
