In a stunning upset at the French Open, Marta Kostyuk eliminated four-time champion Iga Swiatek with a score of 7-5, 6-1, securing her place in the quarterfinals for the first time. Kostyuk, who remains undefeated on clay this season, showcased remarkable defensive skills and capitalized on Swiatek's numerous unforced errors, including critical double faults. The match began with an intense baseline exchange, where Swiatek initially took the lead. However, Kostyuk quickly leveled the score and then took control, winning five consecutive games in the second set. This victory is particularly significant for Kostyuk, as she had previously lost to Swiatek in all three of their past meetings, failing to win a single set. With this win, Kostyuk extends her clay-court winning streak to 16 matches, having recently claimed titles in Madrid and Rouen, France. Meanwhile, Swiatek's performance raises concerns as she has not secured a title on clay since her triumph at the 2024 French Open.
