Four-time French Open champion Iga Swiatek was defeated by Marta Kostyuk in the fourth round of the 2026 tournament, ending her run in straight sets.

Four-time French Open champion Iga Swiatek has been eliminated from the 2026 tournament following a fourth-round loss to Marta Kostyuk. The No. 15 seed secured a 7-5, 6-1 victory over the world No. 3 to advance at Roland-Garros [2].

**Key takeaways**
* Marta Kostyuk defeated Iga Swiatek 7-5, 6-1 to reach the next stage of the tournament [2].
* The win marked Kostyuk’s 16th consecutive victory on clay courts [2].
* Swiatek, who recently turned 25, had previously held a 3-0 record against Kostyuk [2, 3].
* The match concluded on Court Philippe-Chatrier after Swiatek failed to convert a service opportunity for the first set at 5-4 [2, 3].

## A Shift in Momentum on Court Philippe-Chatrier
Entering the match, Swiatek appeared to be in a strong position to contend for another title. She had navigated the early rounds of the tournament with a clear-headed approach, working under the guidance of her new coach, Francisco Roig [3]. The draw had also opened up significantly following the second-round exit of No. 2 seed Elena Rybakina, who was upset by Yuliia Starodubtseva [1, 3]. 

Despite these favorable conditions, Swiatek struggled to maintain control against Kostyuk. Although Swiatek held a lead in the opening set, she was unable to close it out while serving at 5-4, allowing Kostyuk to capitalize on a series of unforced errors [3]. The second set saw Swiatek break in the opening game, but she could not sustain the pressure. As the match progressed, Swiatek’s baseline game faltered, and she struggled to generate free points on her serve, leading to an irretrievable slide in performance [3].

## Why it matters
The loss represents a significant departure from Swiatek’s historical dominance on the red clay of Paris. The defeat follows a period of transition for the four-time champion, who recently parted ways with coach Wim Fissette in an effort to simplify her game and regain the fluid balance between offense and defense that defined her previous success [3]. 

With both Swiatek and the previously eliminated Coco Gauff out of the draw, the 2026 French Open women’s bracket is guaranteed to produce a first-time champion at Roland-Garros [2]. The tournament continues to see high-profile exits, leaving the field wide open as the remaining competitors vie for the title [2].
