Kostyuk and Noskova Bring Two Rivalry Blueprints to New York

Eleventh seed Marta Kostyuk and sixth seed Linda Noskova meet in the US Open fourth round with a first New York quarterfinal at stake. Kostyuk has played the cleaner tournament, while reigning Wimbledon champion Noskova has survived the more demanding pressure tests. Their recent meetings offer opposite tactical blueprints, and the New York hard court sits neatly between the conditions that helped each player impose her game.

Kostyuk is winning the untidy passages

Kostyuk has reached the second week without playing a deciding set. She needed patience in the opening round, then reported that she was satisfied with both her tennis and her physical condition. Against Sloane Stephens, Kostyuk lost a second-set lead and faced a set point, but saved it with an unreturnable serve before winning the final three games.

Her third-round performance against Ekaterina Alexandrova was the sharpest of the run. Kostyuk took time away from a dangerous first-strike opponent, recovered after falling behind early in the second set and swept the remaining games. Previous defeats to Alexandrova had been on her mind, but they did not make her cautious when the match tightened.

The forehand is giving Kostyuk control without demanding a low-percentage finish on every ball. She can dictate through the middle, redirect down the line and use her speed to turn defence into a neutral exchange. That combination also changed her Cincinnati match against Mirra Andreeva, when the forehand began commanding rallies after an uncertain start.

Kostyuk’s broader improvement is in how she treats a poor passage. Her work with Sandra Zaniewska has helped her resist the urge to rebuild everything during a difficult afternoon, and the Stephens match showed the result. The remaining concern is the move from control to closure: her intensity can dip when she gets ahead, and Noskova can punish a short passive spell far more quickly than Kostyuk’s earlier opponents.

There are no reported injury concerns. Kostyuk has moved freely, completed all three matches in straight sets and carries the lighter physical and emotional workload. Her Brooklyn base, the presence of her dogs and the support she has felt in New York have also given her a settled routine away from the court.

Noskova keeps repairing matches she should have finished

Noskova’s adjustment from Wimbledon champion to the North American hard courts was not immediate. Media obligations left little time to absorb the title, and early exits in Toronto and Cincinnati showed that her grass-court authority had not transferred automatically. Her US Open run has been less orderly than Kostyuk’s, but it has repeatedly tested her ability to reset.

Noskova fell two breaks behind Katie Volynets in the opening round after a disrupted preparation and an error-heavy start. She saved set points, stabilized the serve and eventually established her normal weight of shot. Against Lanlana Tararudee, a technical adjustment to the serve gave her a much steadier platform and produced her cleanest performance of the tournament.

The third round against Ann Li contained both sides of Noskova’s current form. She controlled more than a set, failed to consolidate a double-break advantage and missed a match point in the tie-break as her forehand became unreliable. At 2-2 in the decider, Noskova treated the set as a new match and won the final four games, several of them through deuce.

That recovery was strong, but the closing problem remains. Noskova can hurry the forehand and lose some automatic rhythm on serve when the finish comes into view. The finish line, inconveniently, is not a tactical system.

At her best, Noskova earns a short return with the serve and takes the first aggressive forehand before the rally develops. She can also interrupt rhythm with a slice, drop shot or move forward, rather than offering Kostyuk the same pace from the baseline throughout. There are no reported injuries, although Noskova played an extra set in the previous round and expended more emotional energy after letting the second set escape.

The first ball after the serve will set the terms

The two recent meetings showed how sharply conditions can change this matchup. In slower, colder and windier Madrid conditions, Kostyuk attacked Noskova’s second serve, returned deep and made her move immediately after serving. In the Wimbledon final, Noskova’s serve controlled the match, produced short balls and allowed her to strike first before Kostyuk could establish return pressure.

New York should reward Noskova’s serve more than Madrid did, but it will not protect it as completely as Wimbledon grass. Kostyuk does not need spectacular return winners; she needs a high volume of deep returns through the middle or at Noskova’s feet. On a practice court, this would be the repetitive drill: block the first serve deep, step inside the second and make Noskova hit her opening forehand without a stable base.

Noskova’s answer is depth on the first two shots. If she drives Kostyuk behind the baseline immediately, Kostyuk’s speed becomes defensive coverage rather than a platform for counterattack. Noskova will particularly target Kostyuk’s backhand side and attack the second serve through the backhand hip, a pattern that drew loose errors in their Wimbledon meeting.

The forehand exchange will depend on balance rather than raw pace. Noskova carries the heavier point-ending shot from a set position, but her error risk rises when she is pulled wide and asked to accelerate while moving. Kostyuk is more comfortable creating on the run and should look to change the geometry by sending Noskova outside the court before redirecting behind her or down the line.

Kostyuk must also protect her own service games with variety. Repeating the same second-serve location would allow Noskova to stand inside the baseline and begin with full commitment. Kostyuk’s bold serve on set point against Stephens was a good sign, but Noskova will apply that pressure more often and with greater pace.

The opening phase matters because Noskova has started slowly twice in New York, while Kostyuk has generally established her patterns early. The pressure games may matter even more: Kostyuk has become better at staying within her process, whereas Noskova has shown a remarkable ability to discard a lost opportunity and begin again in a decider. Neither player has a home-crowd advantage, and Noskova has already handled a strongly pro-opponent atmosphere against Li.

The main intrigue is whether Kostyuk can apply return pressure before Noskova’s serve and first forehand take command. If rallies regularly reach a neutral third or fourth shot, Kostyuk’s movement, steadier tournament form and willingness to grind the rally become central. If Noskova keeps her service routine unhurried, protects the second serve and lands the first strike deep, the match will resemble the faster of their two recent tactical templates.
