The French Open has already served up some surprising moments this year, but Monday’s shocker really turned heads.

Jessica Pegula, the American world No. 3 and one of the tournament favorites, was knocked out of Roland-Garros in the fourth round by an underdog nobody saw coming — wildcard Lois Boisson.

Pegula’s Strong Start Fades Against French Wildcard

Pegula started the match confidently, winning the first set 6-3 and looking like she might cruise through. But the tide quickly turned.

Boisson, just 22 years old and making her Grand Slam main draw debut this year, fought back hard to claim the next two sets 6-4, 6-4.

Despite Pegula’s efforts, including four break points in the final game, she couldn’t break Boisson’s serve and eventually lost on a powerful forehand winner.

Lois Boisson Becomes France’s Last Hope at Roland-Garros

Boisson’s win wasn’t just a personal breakthrough — it sent waves through the French crowd.

She’s now the only French singles player left in the tournament, men’s or women’s, and the first French wildcard to reach the quarterfinals here since Mary Pierce in 2002.

Before this match, Boisson was ranked 361st in the world, but this victory boosted her live ranking all the way up to No. 120.

Overcoming Injury and Controversy Before the Big Win

Boisson’s journey hasn’t been easy. She spent nearly a year sidelined with an ACL injury, making her rapid rise all the more impressive.

Earlier this year, she was also involved in a strange moment on court when British player Harriet Dart jokingly suggested she needed deodorant during a match at the Rouen Open.

Dart later apologized, but Boisson took it in stride, even joking that Dove should sponsor her.

Talking about the incident, Boisson said it didn’t really bother her.

“It was not difficult to deal with,” she explained. “It was okay. It was nothing for me.

She maybe made a mistake, then I joked about it, that’s it.” Clearly, she’s focused on the bigger picture — proving herself on the biggest stage and chasing her dreams at Roland-Garros.
