Kostyuk stuns four-time champion Swiatek at French Open
Confirmed
What we know
Fifteenth-seeded Marta Kostyuk reached her first French Open quarterfinal Sunday by beating four-time Roland Garros champion and No. 3 seed Iga Swiatek 7-5, 6-1 on Court Philippe Chatrier — on Swiatek's 25th birthday. The Ukrainian, undefeated on clay in 2026 after titles in Madrid and Rouen, had never taken a set in three prior meetings with Swiatek and ended the Pole's run of reaching at least the Paris quarterfinals since 2019.
Kostyuk will face compatriot Elina Svitolina in an all-Ukrainian quarterfinal after the No. 7 seed rallied past Belinda Bencic 4-6, 6-4, 6-0, guaranteeing Ukraine's first women's semifinalist at Roland Garros in the Open era. Swiatek said it "wasn't a good day in the office" after a match marked by her double faults and unforced errors once Kostyuk seized the first set.
