Boisson Stuns French Open: World No. 361 Knocks Out Third Seed Jessica Pegula

22-year-old wildcard becomes lowest-ranked Roland Garros quarterfinalist in over four decades

In a stunning fourth-round upset that has shaken the 2025 French Open, France’s Loïs Boisson—ranked 361 in the world—defeated world No. 3 Jessica Pegula 3-6, 6-4, 6-4. The 22-year-old wildcard, playing in her first-ever Grand Slam main draw, thrilled the Paris crowd on Court Philippe Chatrier with a fearless and emotional performance.

Boisson, who had never before played beyond the qualifying rounds at a major, now finds herself among the final eight at Roland Garros—a feat few could have imagined at the tournament’s start.

Key Moments and Significance:

Boisson is now the lowest-ranked woman to reach a Grand Slam quarterfinal since 2017, and the lowest-ranked at the French Open since the WTA computer rankings began.

After dropping the first set, she rallied back with aggressive baseline play and surprising composure for a Slam debutante.

Pegula, one of the title favourites, struggled with consistency as Boisson capitalised on key break points in the second and third sets.

The French crowd embraced Boisson as a hometown hero, lifting her energy in long rallies and crucial moments.

Her run guarantees her a payday exceeding all her previous career earnings combined—an estimated €400,000 minimum for reaching the quarterfinals.

Up next: Boisson will take on 18-year-old Russian sixth seed Mirra Andreeva in a battle between two rising stars.

“I didn’t expect this,” Boisson said after the match. “I came here to enjoy the experience. Now I’m in the quarterfinals of my home Slam. I’m speechless.”

Whether or not she advances further, Loïs Boisson has already made her mark—turning a wildcard chance into one of the most heartwarming stories of this year’s tournament.
