Coco Gauff defeated Marta Kostyuk 6-2, 6-2 — Cincinnati Open 2026 Quarterfinal.
Coco Gauff and Marta Kostyuk: Coco Gauff leads 3–1 across 4 recorded meetings.
A semifinal spot at the Cincinnati Open cost Gauff 70 minutes, and Kostyuk's service games explain it: the No. 10 seed held twice in seven tries, five double faults arriving in the opening set alone. The fourth seed broke in game 2 of each set, for 2-0 both times, and took 23 of 30 first-serve return points. It answers Kostyuk's straight-sets win at the Qatar Open, her only one in three meetings on record.
