Sinner reaches Cincinnati quarterfinals after defeating Mannarino

Jannik Sinner moved into the Cincinnati Open quarterfinals with a 6-4 7-6(7-4) victory over Adrian Mannarino. Sinner seized control early by breaking in the third game and, despite a rain delay that paused play for nearly three hours, closed out the match in a tense tiebreak. Mannarino, 37, showed stubborn resilience and saved a break point with an ace in the seventh game of the first set, but could not prevent Sinner from advancing. The second set featured another push from Mannarino, including three saved break points at 5-5, but Sinner found the edge in the tiebreak to win 7-4 and extend his perfect record against Mannarino to four wins. In other late matches, Alexander Zverev defeated Brandon Nakashima 6-4 6-4 after rain suspended their encounter overnight. Zverev will face Karen Khachanov next. Holger Rune advanced after Frances Tiafoe retired with a back injury while trailing 6-4 3-1. In the women’s draw, Iga Swiatek beat Sorana Cirstea 6-4 6-3, Magda Linette upset Jessica Pegula 7-6(7-5) 3-6 6-3, and the Cincinnati field kept moving toward the business end of the week.

The match underlined Sinner’s ability to navigate late pressure and adapt after a lengthy rain break, a combination that keeps him on track for deep runs in warm conditions that favor his precise ball striking. Mannarino’s craft and left-handed angles still posed challenges, reminding viewers that a top seed cannot take a win for granted even when momentum seems to tilt in his favor. The wider picture in Cincinnati shows a field with depth at both ends of the draw, where veteran resilience and fresh injuries alter the ladder as hot weather tests endurance. Swiatek’s steadiness in the women’s bracket signals she remains the player to beat, while Linette’s disciplined performance hints at an increasingly competitive field beyond the chalk favorites. Going forward, players will need to balance late-summer form with weather volatility, a combination that can define who makes a real title push.
