Marta Kostyuk vs Katie Volynets — R64 — French Open

Marta Kostyuk lost the opening set in a 7-7 tiebreak, then found her first-serve range to overturn Katie Volynets 6(4)-7(7), 6-3, 6-3. The flip came on serve: Kostyuk won 75% of her first-serve points to Volynets's 57%, and her ball-striking edge stretched to 60 winners against 22. Volynets kept it tidy — zero double faults to Kostyuk's seven — but couldn't withstand the return pressure, surrendering serve as Kostyuk converted 6 of 18 break points in their first clay meeting after splitting two prior matches.
