Top seeds Jannik Sinner and Iga Swiatek advanced in the Cincinnati Masters after overcoming initial challenges in their opening matches. Swiatek, the world number one, faced a tough battle against Varvara Gracheva, ultimately winning 6-0, 6-7 (8), 6-2 after needing six match points. Sinner, the ATP number one, secured a 6-4, 7-5 victory over Alex Michelsen, demonstrating resilience against eight break points. Both players are aiming for better performances than in previous years, particularly Sinner, who has never reached the quarterfinals in Cincinnati. Swiatek expressed relief at maintaining her composure after nearly faltering, while Sinner highlighted his need to acclimatize to the conditions. The victories set up their respective third-round matches, with Swiatek facing Marta Kostyuk and Sinner meeting Jordan Thompson.
