Marta Kostyuk pulled off a stunning upset against world No. 1 Iga Swiatek in the fourth round of the French Open, mounting a gritty comeback after early breaks. The Ukrainian’s backhand winners and resolute defense forced Swiatek into uncharacteristic errors, leveling the first set at 5-5 after a tense rally. Kostyuk broke Swiatek’s serve twice in the set, capitalizing on a double fault and wild forehand from the Polish star.
Swiatek, playing on her 25th birthday, struggled to maintain her usual dominance on the Parisian clay. Her return game faltered at critical moments, while Kostyuk’s aggressive baseline play forced the three-time champion into extended rallies. The match turned decisively when Kostyuk saved multiple break points to hold serve, then broke Swiatek again to take the first set. Crowd favorite Swiatek’s frustration was evident as she missed routine passing shots.
This result reshapes the women’s draw, as top seed Swiatek was heavily favored to defend her title. Kostyuk now advances to the quarterfinals, becoming the first Ukrainian woman to reach that stage at Roland Garros since Elina Svitolina in 2023. The upset also underscores the growing depth in women’s tennis, where unseeded players increasingly challenge established champions.
“Every point is good, every point is high quality,” noted commentator Chrissy as both players traded murderous shots from the baseline. The match showcased elite clay-court tennis, with Kostyuk showing remarkable poise under pressure, recovering from deficits to dictate play. Swiatek’s loss marks her earliest exit at Roland Garros since 2022, when she lost in the quarterfinals.
