Marta Kostyuk knocked out four-time French Open champion Iga Swiatek in straight sets on Sunday, sending the third seed out of Roland Garros at the earliest stage since 2019.
Kostyuk won 7-5, 6-1 to end Swiatek's hopes of a fifth title in Paris. The result ensures a first-time women's singles champion will be crowned this year.
