Jessica Pegula’s French Open campaign ended in stunning fashion as the world No. was upset by 22-year-old French wildcard Lois Boisson in the fourth round at Roland Garros. Pegula, who had never lost to an unseeded player at the tournament and held a dominant 19-2 record against opponents ranked outside the top 100 at Grand Slams, fell 3-6, 6-4, 6-4 to Boisson, ranked 361st in the world.
Boisson, making her Grand Slam main-draw debut, rallied from a set down and used aggressive forehands and clever drop shots to unsettle Pegula, feeding off the energy of a partisan French crowd. Pegula struggled to convert key break points in the deciding set, going just for, while Boisson held her nerve to close out the biggest win of her career.
This loss marks one of the biggest upsets of the 2025 French Open and sends Boisson into the quarterfinals, making her the lowest-ranked player to reach this stage at a Grand Slam since 2017 Pegula’s early exit leaves questions about her clay-court form, while Boisson’s fairytale run continues to capture the tennis world’s attention.
