Marta Kostyuk Stats: How the Ukrainian’s Numbers Tell the Story of a Roland-Garros Breakthrough

Marta Kostyuk’s Roland-Garros run has become one of the most compelling statistical stories of the women’s draw. The Ukrainian, listed as the No. 15 seed, has not simply advanced through high-pressure matches; she has done so by changing the balance of contests through first-strike tennis, return pressure, and a willingness to attack even when the scoreboard demanded control.

The phrase “marta kostyuk stats” now points to more than a player profile or a set of match numbers. It captures a sharp competitive shift: Kostyuk moving from dangerous contender to a player capable of beating elite opponents on one of tennis’s most demanding stages.

Her back-to-back victories over Iga Swiatek and Elina Svitolina at Roland-Garros offer a clear statistical window into that development. Against Swiatek, she produced one of the most notable results of the tournament, defeating the Polish No. 3 seed 7-5, 6-1 in the fourth round on 31.05.2026 at Court Philippe-Chatrier. Two days later, on 02.06.2026, she followed it with a 6-3, 2-6, 6-2 quarter-final win over fellow Ukrainian Elina Svitolina, the No. 7 seed.

Together, those matches show why Kostyuk’s numbers matter: they reveal a player whose game is no longer built only on potential, but on repeatable pressure in decisive moments.

 

The Swiatek Match: A Statistical Statement Against a Former Dominant Rival

Before the fourth-round meeting at Roland-Garros, the head-to-head record between Marta Kostyuk and Iga Swiatek heavily favored the Polish player. The listed history showed Kostyuk with 0 wins and Swiatek with 4 wins across their previous matches.

Those earlier results included Swiatek victories at Roland-Garros in 2021, Indian Wells in 2024, Cincinnati in 2024, and Cincinnati in 2025. The pattern suggested a matchup Swiatek had controlled. But the 2026 Roland-Garros fourth round broke that trend.

Kostyuk’s 7-5, 6-1 win was built on pressure across nearly every statistical category. She hit 5 aces to Swiatek’s 0, immediately showing an edge in free-point creation. Although Kostyuk committed 4 double faults compared with Swiatek’s 5, her serve was far more effective once points began.

Her first-serve percentage stood at 65%, almost identical to Swiatek’s 66%. The difference came in what happened after the first serve landed. Kostyuk won 65% of her first-serve points, while Swiatek won only 45%. That 20-point gap was one of the defining numbers of the match.

Kostyuk also won 44% of her second-serve points, compared with Swiatek’s 35%. In a clay-court match where rallies can quickly become physical and tactical, that second-serve performance mattered. It gave Kostyuk enough stability to stay aggressive without being dragged into constant defensive positions.

Return Pressure Was the Real Difference

The most revealing number from the Swiatek match may be Kostyuk’s 59% receiving points won. Against a player of Swiatek’s quality, that figure is exceptional. It means Kostyuk was not merely waiting for errors; she was consistently making Swiatek play under pressure from the first shot after serve.

Swiatek won only 42% of receiving points, leaving Kostyuk with the stronger balance between service games and return games. That balance showed up in the break-point numbers as well. Kostyuk converted 67% of her break points, while Swiatek converted 33%.

The winners and unforced errors also tell the story of the match’s momentum. Kostyuk finished with 25 winners and 27 unforced errors. Swiatek produced 13 winners and 39 unforced errors. Kostyuk was not error-free, but her aggression carried a much higher reward. Swiatek, by contrast, was pushed into a pattern where mistakes outweighed attacking success.

By the end, Kostyuk had won 79 total points to Swiatek’s 57. That 22-point gap reflected more than a narrow upset. It showed clear scoreboard control, especially after a tight first set gave way to a decisive second.

What the Swiatek Stats Reveal About Kostyuk’s Evolution

The statistical profile of the match points to a player who has learned how to convert athleticism into match management.

Kostyuk has long been known for clean ball-striking, explosive movement, and emotional intensity. Against Swiatek, those traits were organized into a coherent plan. She served with enough authority to avoid constant pressure. She returned aggressively enough to take away rhythm. She came forward effectively, winning 70% of net points, compared with Swiatek’s 63%.

That net-point figure is important because it shows Kostyuk was not limited to baseline exchanges. She was willing to close space, finish points, and prevent Swiatek from resetting rallies. On clay, where many players hesitate to come forward, that willingness gave her another tactical layer.

Her performance did not look like a one-dimensional power display. It looked like a player using speed, timing, court position, and controlled aggression to rewrite a difficult head-to-head matchup.

The Svitolina Quarter-Final: Power, Resilience, and a Ukrainian Duel

The quarter-final against Elina Svitolina offered a different kind of statistical test. Unlike the Swiatek match, where Kostyuk overturned a lopsided rivalry, the Svitolina matchup carried national and emotional weight. Both players represented Ukraine, and the match placed two generations of Ukrainian women’s tennis on the same stage at Court Philippe-Chatrier.

The head-to-head record listed before this recent meeting showed 1 win for Svitolina and 1 win for Kostyuk across 2 matches. Svitolina had beaten Kostyuk at the Australian Open in 2018, while Kostyuk defeated Svitolina in Toronto in 2024.

At Roland-Garros, Kostyuk won 6-3, 2-6, 6-2. The set pattern was telling. She started strongly, lost control in the second set, then reasserted herself in the decider. That kind of result often reveals more than a straight-sets win because it shows how a player responds after momentum turns against them.

Kostyuk’s Winners Carried the Quarter-Final

Against Svitolina, Kostyuk hit 33 winners compared with Svitolina’s 23. That 10-winner advantage was crucial, especially because Kostyuk also committed more unforced errors: 37 to Svitolina’s 25.

The match therefore followed a familiar Kostyuk pattern: high-risk, high-reward tennis. But the numbers show that the risk was productive enough to win. Kostyuk’s attacking output allowed her to dictate more points, and her total points won — 84 compared with Svitolina’s 75 — confirmed that her aggression held up across three sets.

Her serve again played a major role. Kostyuk struck 4 aces, while Svitolina hit 0. Both players committed 3 double faults, so the difference was not in avoiding serve-related mistakes but in generating more direct value from the serve.

Kostyuk landed 65% of her first serves, compared with Svitolina’s 56%. She also won 70% of first-serve points, while Svitolina won 60%. That combination gave Kostyuk a strong platform, especially in the first and third sets.

The second serve was less secure. Kostyuk won only 32% of second-serve points, compared with Svitolina’s 42%. That statistic helps explain why the match became complicated in the middle. When Kostyuk missed first serves, Svitolina had chances to attack and extend rallies on her terms.

Still, Kostyuk compensated with stronger return production. She won 48% of receiving points, compared with Svitolina’s 43%. That edge allowed her to keep applying pressure even when her own service games became vulnerable.

Break Points and Net Play: The Margins That Decided the Match

Kostyuk won 55% of break points against Svitolina, while Svitolina won 63%. On the surface, that category favored Svitolina. But Kostyuk’s broader point production and stronger first-serve numbers allowed her to survive the moments when Svitolina was more efficient on break chances.

At the net, Svitolina actually held the statistical edge, winning 74% of net points to Kostyuk’s 68%. That suggests Svitolina was effective when she moved forward, but Kostyuk’s heavier baseline output and higher winner count created more total damage.

The match therefore came down to volume and initiative. Svitolina found pockets of efficiency, especially in the second set. Kostyuk, however, produced more attacking tennis over the full match and finished with 9 more total points.

Comparing the Two Matches: What Kostyuk’s Stats Have in Common

Across the Swiatek and Svitolina matches, several themes stand out.

First, Kostyuk’s first serve has become a foundation. She landed 65% of first serves in both matches. That consistency gave her a reliable entry point into rallies, even against opponents with very different styles.

Second, her ace count mattered. She hit 5 aces against Swiatek and 4 against Svitolina, while both opponents finished with 0. On clay, where aces are harder to produce than on faster surfaces, that edge is valuable. It gave Kostyuk quick points and helped her avoid being forced into long exchanges every time she served.

Third, her return game was central. She won 59% of receiving points against Swiatek and 48% against Svitolina. Those numbers show a player who is not simply holding serve and waiting for chances. She is actively creating pressure on return, forcing opponents into uncomfortable service games.

Fourth, her winners came with errors, but the overall equation worked. Against Swiatek, she hit 25 winners and 27 unforced errors. Against Svitolina, she hit 33 winners and 37 unforced errors. Those are not conservative profiles. They reflect a player willing to accept mistakes as the cost of control.

The key is that her opponents could not match her offensive output. Swiatek hit 13 winners; Svitolina hit 23. Kostyuk’s ability to outpace both opponents in winners gave her a clear attacking identity.

Why “Marta Kostyuk Stats” Now Means More Than Numbers

Statistics in tennis are most useful when they explain the shape of a player’s game. In Kostyuk’s case, the numbers from Roland-Garros show a competitor who is increasingly comfortable taking responsibility for the match.

She is not relying only on opponent errors. She is creating winners, attacking second serves, stepping into returns, and pushing forward when the opportunity appears. The figures also show that she is willing to play through imperfection. Her unforced-error totals were not low, particularly against Svitolina, but her offensive pressure remained strong enough to decide the result.

This matters because elite tennis is rarely about playing cleanly from start to finish. It is about choosing the right risks, sustaining belief after mistakes, and imposing patterns under pressure. Kostyuk’s recent Roland-Garros stats suggest she is finding that balance.

The Ukrainian Context Adds Weight to the Run

The quarter-final against Svitolina carried significance beyond rankings and match statistics. Both players are major Ukrainian figures on the women’s tour, and their meeting at Roland-Garros represented the depth of Ukrainian tennis at the highest level.

Svitolina has long been one of Ukraine’s most recognizable tennis names, while Kostyuk’s rise reflects a newer wave of Ukrainian talent. Their quarter-final was therefore not only a contest between two seeded players; it was also a marker of national presence in a major tournament.

For Kostyuk, winning that match after defeating Swiatek strengthened the sense that her run was not built on a single upset. It was a sequence. She backed up one major result with another, under a different kind of pressure.

The Future Outlook: What These Stats Suggest Next

Kostyuk’s Roland-Garros numbers point toward a player whose ceiling is rising because her core strengths are translating against elite opposition.

Her serve is becoming more than a way to start points. Her return game is becoming a weapon. Her winner production shows that she can take control against both defensive and attacking opponents. Most importantly, her total-points advantage in both matches shows that the scorelines were supported by sustained performance, not isolated bursts.

There are still areas to monitor. The second-serve win percentage against Svitolina, at 32%, left her vulnerable. The unforced-error count, particularly 37 in the quarter-final, also shows the risk in her attacking style. Against the very best players, those margins can become dangerous if the winners do not keep flowing.

But the broader trend is positive. Kostyuk is showing that she can win on clay through pressure, not patience alone. She can beat a player who had dominated their rivalry. She can survive a three-set national derby against a seasoned opponent. She can turn statistical aggression into major-tournament progress.

Conclusion: Kostyuk’s Numbers Show a Player Arriving on Her Own Terms

Marta Kostyuk’s stats from Roland-Garros tell a clear story of competitive maturity. The 7-5, 6-1 win over Iga Swiatek showed her ability to dismantle a difficult matchup through return pressure, first-serve effectiveness, and controlled aggression. The 6-3, 2-6, 6-2 victory over Elina Svitolina showed her resilience, shot-making volume, and capacity to recover momentum after a difficult second set.

The numbers are not perfect, and that is part of what makes them revealing. Kostyuk’s game still carries risk, but it now carries authority as well. She is no longer just producing flashes of elite tennis. At Roland-Garros, she has turned those flashes into results.

For readers searching for “marta kostyuk stats,” the answer is not only found in aces, winners, break points, or total points won. It is found in the pattern behind them: a player becoming more aggressive, more composed, and more capable of shaping big matches on her own terms.
