Marta Kostyuk defeated Mirra Andreeva 4-6, 6-0, 6-2 — Cincinnati Open 2026 R16.
Marta Kostyuk and Mirra Andreeva: Marta Kostyuk leads 3–1 across 4 recorded meetings.
Broken in game 1 and again in game 10, Kostyuk lost the opener to the opponent who had beaten her in a French Open semifinal in June. Then Andreeva's first serve folded. Her first-serve points won fell from 88 percent in that set to 38 in the second, and Kostyuk, who takes the ball early on return by design, broke in game 2 for 2-0 and again in game 4 for 4-0, converting 4 of 5 break points while the fifth seed held only 7 of 11 service games. The win moves the Ukrainian to 7-5 against top-8 opponents this season. Ninety-three minutes, and the No. 10 seed is into the Cincinnati quarterfinals.
