Marta Kostyuk dismantled Caty McNally 6-2, 6-3 in the Madrid Round of 16 on Monday, converting 6 of 13 break points and winning 68% of first-serve points to extend her undefeated run at the clay court Masters event. The Ukrainian broke McNally’s serve six times while surrendering just three breaks to advance to the quarterfinals in 89 minutes.
Kostyuk seized control early, breaking twice in the opening set while McNally’s second serve faltered at just 27% points won. The American briefly found rhythm in the second set, leveling at 3-3 after saving four break points in the sixth game. But Kostyuk’s superior firepower — she hit 2 aces compared to McNally’s zero and won 76 of 135 total points — proved decisive as she reeled off the final three games.
The Ukrainian closed out the match by winning 43% of her second-serve points, a significant advantage over McNally’s woeful 27%. Despite landing just 57% of first serves, Kostyuk’s 68% win rate on those deliveries outpaced McNally’s 52%, even though the American found 67% of her first serves.
Key Takeaways
- Kostyuk’s return game was relentless, converting 6 of 13 break point opportunities (46%) while McNally managed just 3 of 10 (30%). The Ukrainian created 13 break chances to McNally’s 10 despite facing fewer total return games.
- McNally’s second serve became a liability, winning only 27% of those points compared to Kostyuk’s 43%. That 16-percentage-point gap translated to Kostyuk winning 76 total points to McNally’s 59 — a 17-point margin that tells the story of the match.
- Despite landing 10 percentage points fewer first serves (57% vs 67%), Kostyuk dominated those deliveries at 68% points won, a full 16 points better than McNally’s 52%. The Ukrainian’s superior court positioning and shot selection neutralized the American’s consistency advantage.
- Kostyuk’s 5 double faults to McNally’s 2 hardly mattered — the Ukrainian’s aggressive serving generated 2 aces and kept McNally off-balance. In contrast, McNally’s safer approach yielded zero aces and couldn’t prevent Kostyuk from dictating rallies.
Player Analysis
Marta Kostyuk
The Ukrainian delivered her most complete performance of the Madrid fortnight, building on her stunning upset of Jessica Pegula in the previous round. Her 68% first-serve win rate and 43% second-serve points won demonstrated tactical maturity — she picked her spots to attack while maintaining defensive solidity when McNally pressed. Converting 6 of 13 break points showed clinical efficiency, and her ability to win 76 of 135 total points reflected sustained pressure throughout.
Five double faults reveal the only blemish in an otherwise dominant display. Kostyuk’s willingness to take risks on serve — evident in her 2 aces and aggressive placement — occasionally backfired, but the reward vastly outweighed the risk. Her serve-plus-one patterns and ability to close out the final three games without facing a break point underscored her growing confidence on clay.
Caty McNally
McNally’s 67% first-serve percentage and disciplined ball-striking kept her in contention through the first set and into the second, but she couldn’t sustain the level needed against a higher-ranked opponent firing on all cylinders. Winning just 52% of first-serve points exposed a lack of firepower — she failed to generate a single ace and couldn’t capitalize on Kostyuk’s 5 double faults.
The American’s second serve crumbled under Kostyuk’s relentless returning, yielding a dismal 27% points won. Converting only 3 of 10 break points proved fatal; she had opportunities to level the match but couldn’t execute in the crucial moments. McNally’s perfect Madrid run ended not due to poor tennis, but because she lacked the weapons to hurt an in-form Kostyuk who won 17 more total points.
