Jessica Pegula was the latest victim of a French Open upset, having lost her fourth round meeting with Lois Boisson.
Pegula enjoyed the atmosphere against Boisson despite the result, where she lost 3-6, 6-4, 6-4 to the WTA number 361.
Boisson now takes on Mirra Andreeva in the quarter-finals of the French Open, where she is playing in her first Grand Slam main draw.
Mats Wilander believes Boisson is a real threat at Roland Garros, with sixth seed Andreeva now standing in her way of a semi-final spot.
The 22-year-old wildcard is contesting only her second tour-level event, and took two hours and 40 minutes to pull off the upset against Pegula.

What Jessica Pegula thinks of Lois Boisson after shock French Open loss
The fans at Court Philippe-Chatrier were overjoyed with the result, having last seen a French woman reach the quarter-finals back in 2017.
Sharing her verdict on her rival, Pegula said of Boisson post-match: “All she wants to do is hit forehands. She is really good at moving.

“She is really fast so she is really good at running around to get her forehand and also covering the forehand side. She hits it pretty heavy.
“It’s super high and heavy when she wants to and she needs to get back in the point and then she is able to use her drop shot and slice. She is really quick, so it keeps her in a lot of points and I think she did that really well today.”
Jessica Pegula responds when asked what level Lois Boisson can reach on the WTA Tour
Boisson is currently following in the footsteps of both Caroline Garcia and Kristina Mladenovic, who made the last eight back in 2017.
And she won’t want to end her dream run there, although she can hold her head extremely high regardless of her final position.

Currently ranked outside the WTA top 350, Boisson managed to reach her career-high rank of 152 this time last year.
But that is all set to change after the French Open, with the 22-year-old set for a new career-high rank once the event is complete.
A spot around the 120 mark is on the cards, although another big win could see her rise all the way inside the top 70.
When asked what level she thinks Boisson can reach in the future, Pegula responded: “She played really well.
“I think she has won a lot of matches recently and if it’s at a lower level and not WTA level it doesn’t really matter when you are winning matches.
“The way she plays, being tough in those moments really helps so I thought she did a good job of that today.
“If she plays like that I think she will do well, especially on the clay. I don’t know how she does on other surfaces, I have no idea, but I would imagine clay is definitely going to be her best surface.”
