Marta Kostyuk staged a commanding comeback to defeat Caty McNally 2-6, 6-2, 6-1 in the Round of 16 at Rouen on April 15, 2026. After dropping the opening set, the Ukrainian flipped the script with superior serving efficiency—winning 69% of first-serve points compared to McNally’s 48%—and finished with an 88-69 edge in total points won.
McNally’s controlled start unraveled as Kostyuk cranked up the aggression. The American’s 69% first-serve percentage couldn’t mask her inability to capitalize on those deliveries, managing just 48% of points won behind her first ball. Kostyuk, meanwhile, found rhythm on serve in the second set and never looked back, hitting three aces to McNally’s zero and committing one fewer double fault despite her naturally riskier game style.
The third set became a rout. Kostyuk reeled off five consecutive games at one stage, dismantling McNally’s defensive structure with offensive firepower that has become her signature on hard courts—a high-risk, high-reward approach that averages 67 winners per match in recent outings. McNally, stuck in a 3-7 hard-court slump entering this tournament, had no answers once momentum shifted.
Key Takeaways
- Kostyuk’s first-serve dominance proved decisive: she won 69% of points behind her first delivery, a 21-percentage-point margin over McNally’s woeful 48% conversion rate despite the American’s superior 69% serve placement accuracy.
- The Ukrainian’s 88-69 advantage in total points won underscores the comprehensive nature of her turnaround—she outscored McNally by 19 points across the final two sets after trailing in the opener.
- McNally’s serving woes extended beyond point conversion: her three double faults to Kostyuk’s two, combined with zero aces, left her without the free points needed to hold off an aggressive baseliner hitting 3.7 aces per match on average this hard-court season.
- Kostyuk’s comeback fits her recent pattern of explosive momentum shifts—she’s averaged 67 winners per hard-court match, an attacking profile that generates either dominant victories or high-error defeats, and today the aggression paid off spectacularly in sets two and three.
Player Analysis
Marta Kostyuk
Kostyuk’s performance was a textbook example of her high-variance playing style paying dividends. After a shaky first set where McNally’s steadiness frustrated her, the Ukrainian recalibrated and unleashed the offensive firepower that defines her hard-court game. Her 69% win rate on first serves dwarfed McNally’s efficiency, and the three aces—right at her 3.7 per-match average—provided crucial free points at pivotal moments. The second-serve numbers (46% points won for both players) suggest Kostyuk didn’t necessarily elevate defensively, but rather dominated with her primary weapon.
What stands out is her ability to flip matches once momentum shifts. This isn’t the first time she’s turned a deficit into a rout—her recent form includes a 6-2, 6-4 win over Kamilla Rakhimova at Miami, and today’s 6-1 third set continues that trend. The 88 total points won, nearly 20 clear of McNally, reflect complete control once she found her range. With her second career title still in sight, this comeback performance signals dangerous form heading into the quarterfinals.
Caty McNally
McNally’s opening set was everything her game is designed to be: clean, controlled, and error-averse. Her 69% first-serve percentage gave her the platform to dictate, and she capitalized to take the set 6-2. But the wheels came off spectacularly once Kostyuk began swinging freely. The American’s inability to win even half her first-serve points (48%) exposed a fundamental issue—she lacks the weapons to punish opponents when they step inside the baseline and take control of rallies.
The zero aces tell a damning story for a player who averages 3.1 per match on hard courts. Without free points on serve, McNally had no margin for error against an opponent hitting through her. Her three double faults didn’t help, nor did the identical 46% second-serve win rate—when both players are that vulnerable on second deliveries, the one dictating with the forehand wins, and that was never going to be McNally today. Now 3-7 in her last 10 hard-court matches, she’ll need to rediscover the offensive punch that earned her a career title if she’s to arrest this slide.
