World number three Jessica Pegula has crashed out of the French Open in the fourth round after a shocking defeat to home hope Lois Boisson.
Boisson, ranked 361st in the world, came back from a set down to overcome the American 3-6, 6-4, 6-4.
She entered the tournament as a wildcard and will now play in a Grand Slam quarter-final, just four months after returning from a torn ACL.
Pegula had struggled on clay coming into Roland Garros, but showed promising signs at the tournament, dropping just one set in her first three matches.
The former US Open finalist has now bowed out in Paris, however, and is the second top-five player to exit the French Open, following Jasmine Paolini’s loss to Elina Svitolina.
Following the shocking result, British tennis legend Tim Henman reacted to the brilliance of Pegula‘s conqueror.

Speaking on TNT Sports after the match, Henman said: “It’s just incredible to see someone like that ranked outside the top 350 against a top-five player and with that competitive spirit.
“You can’t turn to your teammates, you’ve got to find a way to get the job done, and I thought she had the courage and conviction to keep getting that forehand into play.
“She could hardly breathe out there, she was so tight, but she got it done and what an ovation from the crowd.
“It’s just unbelievable, and we’ve all been around the game for a long, long time, but the lack of scripts in live sport, you just don’t know what’s gonna happen.
“Before that match, I’m thinking well, I hope she goes out there and enjoys her time on [Court Philippe] Chatrier, she’s playing Jess Pegula, three in the world, and I think after losing the first set 6-3, she settled down. To win in front of her home fans is just so special.”
Lois Boisson makes history after defeating Jessica Pegula at Roland Garros
At 22 years of age, Lois Boisson becomes the third youngest French woman in the Open Era to reach the quarter-finals at Roland Garros.
She trails only Brigitte Simon, who achieved the feat at 21 in 1978, and Mary Pierce, who in 1994, aged 19, became the youngest of her compatriots to reach the last eight at the French Open since 1968.
Boisson will face Mirra Andreeva in the next round, in a first career clash between the two players.
Andreeva booked her place in the quarter-finals after triumphing over Daria Kasatkina in straight sets.
