Jessica Pegula explained her unexpected defeat to wildcard Loïs Boisson in the fourth round of the 2025 French Open, shedding light on the factors behind the loss during her first-ever encounter with Boisson on the WTA Tour. The upset took place at Roland Garros, marking a significant moment in Pegula’s 2025 clay-court Grand Slam run.
Details Behind Pegula’s Fourth Round Defeat at Roland Garros
Entering the tournament as the third seed, Pegula began her French Open campaign with a commanding 6-2, 6-4 victory over Anca Todoni. She then secured a straight-sets win against fellow American Ann Li, 6-3, 7-6(3), followed by a tough three-set battle against Markéta Vondroušová, emerging 3-6, 6-4, 6-2 to reach the fourth round. Her run ended after dropping a tightly contested match to the young French player Loïs Boisson, 6-3, 4-6, 6-4.
After the match, Pegula reflected on the dynamics that swayed the outcome in Boisson’s favor. While Pegula felt that her play in the opening set was solid, she acknowledged that Boisson’s serving proved consistently superior throughout the contest, shaping the match’s direction.
I honestly don’t think I was that surprised by how she played. I felt like the match turned into exactly how she wanted to play, and that’s unfortunate for me. I think I did a good job in the first set, but at the same time, she definitely served better,
Pegula said.

Analyzing Boisson’s Strengths and Missed Opportunities for Pegula
Pegula recognized Boisson’s ability to deliver powerful forehands and generate high, heavy shots that challenged her defensive game. She noted that Boisson’s effective use of drop shots shifted dramatically after the first set, becoming a decisive factor in Boisson’s victory.
I felt like in the first set she missed every drop shot, and then in the second and third she made every single one, and I didn’t really do a good job with those points. But I felt like she honestly played how I thought she would play, look for forehands, hit super high, super heavy at times, and I again had like a million chances and it just didn’t go my way in those kinds of big moments,
Pegula added.
