Kostyuk defeats – Marta Kostyuk reached the French Open quarterfinals for the first time by beating four-time champion Iga Swiatek 7-5, 6-1 on Sunday, spoiling Swiatek’s 25th birthday and snapping a long clay dominance edge.
PARIS — The birthday moment never arrived for Iga Swiatek. By the time she briefly left the court after the opening set, Marta Kostyuk had already turned celebration into damage control, and the numbers kept widening.
On Sunday at the French Open. Kostyuk reached the quarterfinals for the first time by defeating the four-time champion 7-5. 6-1. ruining the day Swiatek turned 25. The Ukrainian. who is undefeated on clay this season. had lost their three previous matches and had never taken a set against Swiatek. yet she arrived prepared to defend her way through a match that started tense and stayed that way.
Kostyuk’s work was relentless from the baseline. She chased Swiatek’s shots all over the court and landed stunning groundstroke winners while Swiatek. undone by mistakes. struggled to find rhythm. From the start, an intense baseline battle unfolded. Swiatek earned the first break after overwhelming Kostyuk after a long rally with a backhand winner.
Kostyuk answered immediately, breaking back, but then dropped her serve again, handing Swiatek a 5-4 lead. The set began to tilt as Swiatek’s crisp control met a sudden wobble. Kostyuk showed signs of nerves too, double-faulting, shanking a forehand wide, and then missing a volley at the net. That opened the door for Swiatek to level the pressure again. as she hit two more double faults in the 12th game and the 15th-seeded Ukrainian ultimately sealed the set with a backhand passing shot.
After that, Swiatek briefly left the court. While she gathered herself, Kostyuk stayed ready—stretching and hopping beside her chair—then received applause as she did a few dance moves to the music playing in the stadium.
The atmosphere shifted outside the lines as well. Following a first week marked by a suffocating heatwave, relief finally arrived in Paris on Sunday, with temperatures dropping to 21 degrees C (70 F) around midday.
When play resumed, Swiatek broke, but the follow-through didn’t last. Another double fault and more unforced errors pulled her down quickly, bringing Kostyuk back at 1-1. Then came the swing that turned a birthday into a rout: Kostyuk won the last five games to take the match into the second set with momentum that looked impossible to interrupt.
In the end, Kostyuk’s second-set performance delivered the kind of statement match that changes narratives. The win also carried personal history. Kostyuk had reached the fourth round at Roland Garros in 2021, where she lost to Swiatek.
This time, she arrived with form that kept stacking. The 15th-ranked Ukrainian extended her winning streak on clay to 16 matches. Ahead of Roland Garros, she won in Madrid—the biggest title of her career—after claiming another clay-court title in Rouen, France.
Swiatek’s season on clay tells a different story. She has not won a title on clay since the 2024 French Open, and Sunday’s loss ensured her birthday day would be remembered for what went wrong, not what she had hoped to celebrate.
