Kostyuk ‘still in shock’ after ending former champion Swiatek’s French Open run in last 16

Kostyuk embraces underdog tag despite 15-match win streak on clay

Marta Kostyuk beat world No. 1 Iga Swiatek 7-5 6-1 to reach her first Roland Garros quarter-final, extending her clay winning streak to 15 matches after taking the Madrid Open as the 26th seed. The result signals a genuine shift in clay-court depth: Swiatek's dominance on the surface is no longer a given, and Kostyuk's consistency-first approach is delivering results despite competing under extreme personal pressure.
