Marta Kostyuk produced one of the biggest upsets of the French Open 2026 on Sunday, defeating four-time champion Iga Swiatek 7-5, 6-1 to reach the quarterfinals at Roland Garros for the first time in her career. The 15th-seeded Ukrainian ended Swiatek's impressive clay-court run this season and ensured that the women's singles draw will crown a first-time champion in Paris this year.

Kostyuk's victory set up an all-Ukrainian quarterfinal clash with seventh-seeded Elina Svitolina, who battled back from a set down to defeat Belinda Bencic 4-6, 6-4, 6-0. The result guarantees that a Ukrainian woman will reach the semifinals at Roland Garros for the first time in the Open Era, marking a significant milestone for the country's tennis history.

Reflecting on the achievement, Svitolina highlighted the importance of the moment for Ukraine amid the ongoing conflict with Russia. She described the prospect of a Ukrainian semifinalist as inspiring for young players back home and a symbol of resilience during a challenging period for the nation. The success of both Kostyuk and Svitolina has added an emotional dimension to Ukraine's presence at this year's tournament.

The exits of Swiatek and Coco Gauff have completely opened up the women's draw, with none of the remaining contenders having previously won the French Open title. A similar situation has emerged in the men's competition following the departures of top names including Novak Djokovic and Jannik Sinner, while Carlos Alcaraz was unable to compete due to injury.

In the men's singles draw, Spanish teenager Rafael Jodar advanced to his maiden Grand Slam quarterfinal after recovering from two sets down to defeat Pablo Carreno Busta 4-6, 4-6, 6-1, 6-2, 6-2. Jodar will next face second seed Alexander Zverev, who secured a straight-sets victory over Jesper de Jong. The result continued a breakthrough tournament for the young Spaniard, who also endured a five-set battle in the previous round.

Brazil's Joao Fonseca continued his remarkable run by defeating two-time French Open runner-up Casper Ruud 7-5, 7-6 (8), 5-7, 6-2. The 19-year-old had already attracted attention by eliminating Djokovic in the previous round and now advances to face Czech youngster Jakub Mensik, who overcame Andrey Rublev in a five-set contest. With several established champions already out of contention, the tournament is increasingly shaping up as a showcase for tennis' next generation.
