Marta Kostyuk reaches the French Open women’s quarterfinals for the first time after defeating Iga Swiatek, a four-time champion and former world No. 1. Playing at Roland-Garros on Sunday, May 31, Kostyuk—seeded 15th—wins in straight sets, 7-5, 6-1, ending Swiatek’s run and also denying her a birthday celebration, with Swiatek turning 25 that day. The match follows a season trend for Kostyuk: she is undefeated on clay heading into the French Open and had previously lost three matches against Swiatek. While Kostyuk had never taken a set from Swiatek before Sunday, she converts that clay form into a breakthrough result at a Grand Slam. With Swiatek eliminated, no player remaining in the draw has previously won the French Open women’s singles title. The French Open quarterfinal field continues after Coco Gauff’s elimination on Saturday, leaving Kostyuk as one of the remaining contenders for the next stage.
