Lois Boisson achieves incredible French Open feats with stunning Jessica Pegula win
Lois Boisson pulled off one of the biggest upsets in French Open history as she stunned world No 3 Jessica Pegula inside a raucous Court Philippe Chatrier.
World No 361 Boisson battled from a set down to shock third seed Pegula 3-6, 6-4, 6-4, breaking in the penultimate service game of the match before holding her nerve to seal victory.
The 22-year-old had never played a Grand Slam tournament before Roland Garros this year and had never faced a player inside the top 50 of the WTA Rankings.
Her incredible triumph cements a remarkable comeback, with the Frenchwoman having been sidelined for nine months across 2024 after an anterior cruciate ligament injury.
“I’m not quite sure what to say, but playing on this court with this atmosphere was amazing, so thank you very much,” said Boisson to her home crowd on court.
“I knew before the match there was a possibility [of an upset], but I knew it was going to be very, very tough.
“I gave it my all and in the end I won, which is incredible.”
Boisson was meant to make her French Open debut as a wildcard before her ACL injury in 2024, though she was later handed a wildcard into the draw this year once she returned to action.
Now, she is just the second wildcard in the Open Era to reach the last eight of the women’s singles draw in Paris, following in the footsteps of French tennis icon Mary Pierce in 2002.
Aged 22 years and nine days, Boisson is also the third-youngest woman to reach the quarter-final of her home major.
Pierce (19 years and 128 days, 1994) and Brigitte Simon (21 years and 209 days, 1978) are the only younger Frenchwomen in the Open Era to progress to the last eight.

Ranked 361st in the world, Boisson is the lowest-ranked Grand Slam quarter-finalist since Kaia Kanepi (world No 418) at the 2017 US Open, excluding unranked players.
The 22-year-old is also the lowest-ranked French Open quarter-finalist in the past four decades, and is the first Frenchwoman to reach the last eight at Roland Garros since Caroline Garcia and Kristina Mladenovic in 2017.
Boisson is currently ranked outside the top 300 largely due to her injury, having fallen outside of the top 500 of the world earlier in 2025.
However, she is now in line for a stunning rankings boost – and is set to eclipse her previous career-high ranking of world No 152.
Boisson is currently leaping 241 places to world No 120 in the WTA Live Rankings, and will soar inside the top 100 should she beat sixth seed Mirra Andreeva in the quarter-finals.
World No 6 Andreeva sealed her place in the last eight earlier in the day thanks to a 6-3, 7-5 victory over 17th seed Daria Kasatkina.
She has now also earned a staggering €440,000 ($503,000) for her run to the last eight, having previously earned just $148,009 in her career.
