Iga Swiatek suffers unexpected defeat to Marta Kostyuk in Roland Garros round of 16

Paris – May 31, 2026: Iga Świątek, the special Polish player who has won the French Open four times, was defeated on Sunday in the round of 16 by Marta Kostyuk. The Ukrainian tennis player, who recently showed strong form on clay courts, secured the victory at Porte d’Auteuil with tactically clever and mentally strong play. Kostyuk extended her unbeaten streak on her preferred surface, while Świątek had to end her challenge for another Grand Slam title early.

The match quickly developed into a contest showcasing Kostyuk’s diverse playing style. She continuously pressured Świątek with refined slices and topspin shots, and Świątek could not find her rhythm. The 19-year-old Ukrainian showed exceptional composure and consistently capitalized on the opportunities presented. Known for her powerful forehand attacks, Świątek appeared noticeably unsettled and made more errors than usual.

This defeat brought a major shift in the tournament dynamics. Świątek was considered the top favorite to win this season’s highlight event, having dominated the clay courts in Paris in 2020, 2022, 2023, and 2025. In contrast, Marta Kostyuk has proven her rising career with successive important victories over established contenders on the WTA Tour and her perfect clay court record remains intact.

The match lasted nearly two hours and was decided after several intense rallies. Kostyuk’s consistency and smart court utilization forced the Polish player into defense. The Ukrainian used a powerful and varied serve, demonstrating tactical maturity at critical moments against the experienced Świątek.

Świątek will need to regroup for the remainder of the season and has taken a hit with this early exit. However, for Kostyuk this win was an important milestone that significantly advanced her position in the Roland Garros draw and boosted her confidence. The tournament has lost a major title contender but at the same time, the tension in the new title race has intensified.

Marta Kostyuk’s next opponent at Roland Garros is not yet determined, but with this victory she sent a clear signal to her competitors: she is ready to compete on the big stage. This Grand Slam tournament held in the French capital promises even more exciting and spectacular matches ahead.

Roland Garros remains a stage for dramatic turnarounds, where not only experienced champions but also young talents like Marta Kostyuk can seize their chances. This French clay court season has thus opened another dramatic chapter, further elevating the tournament’s standing in international tennis.
