The French Open continued to deliver surprising results on Sunday as Marta Kostyuk produced a major upset by defeating former champion Iga Swiatek in the fourth round.Swiatek, who was celebrating her 25th birthday, suffered a 7-5 6-1 defeat that ended her hopes of a fifth Roland Garros title.

The loss came during a turbulent spell at the tournament, which has already seen several top names exit early, including Jannik Sinner, Novak Djokovic and defending women’s champion Coco Gauff.

Kostyuk, seeded 15th, played with growing confidence on clay this season and controlled key moments of the match, especially after edging a tight first set and then accelerating in the second.

The Ukrainian said she was still in shock after reaching her first French Open quarter-final, adding that she focuses on enjoying the game rather than purely chasing results.Swiatek admitted it was a difficult performance, stating she struggled to maintain her desired level and could not manage key moments effectively.

The defeat marks her earliest exit at Roland Garros since her debut in 2019 and extends her wait for another clay-court title, with her last French Open victory still two years ago.

Elsewhere in the draw, Alexander Zverev continued his steady progress, defeating Jesper de Jong in straight sets to remain on track for a maiden Grand Slam title.The men’s and women’s tournaments are now guaranteed to produce new champions this year, adding to the sense of unpredictability in Paris.

Veteran Sorana Cirstea also impressed by reaching her first French Open quarter-final in 17 years, highlighting the tournament’s mix of emerging talent and experienced players making unexpected runs.

Kostyuk will next face Elina Svitolina in an all-Ukrainian clash, promising another high-intensity encounter as the competition intensifies towards the latter stages.
