Pegula, 31, headed into the tournament as the third seed. However, last year's US Open finalist struggled to live with the energetic Boisson, but ultimately hailed the home crowd despite her .

"It was a really good atmosphere," Pegula told the press after the game. "I felt like the crowd was really good. They were being supportive but I felt respectful at the same time so it was a really nice atmosphere.

"I think it definitely helped her pull through at certain points which were really tough there. I guess I am disappointed with the result but it is what it is."

The rookie had to fight off four breakpoints as she served for the match, with the crowd serenading her with chants and cheers. Pegula later revealed that the fans in Paris began to force a shift in the game as time elapsed.

"I think once the match got going, at the beginning it wasn't that much," she added. "But at the end of the second and the third it was full stands and for her. It was a great atmosphere.

"Then like I said I did not feel they were being disrespectful at all. I felt like it was a really fun and good atmosphere. Obviously for her but at the same time it was great, I thought it was really nice."

While known for her skills on the court, Pegula is also renowned as the daughter of Terry Pegula, who owns the NFL's Buffalo Bills and NHL side Buffalo Sabres, who boasts a net worth of £6billion. Afterwards, the world No. 3 admitted that she wasn't firing on all cylinders in the contest.

"I felt like in the first set she missed every drop shot, and then in the second and third she made every single one, and I didn't really do a good job with those points," she said.

"But I felt like she honestly played how I thought she would play, look for forehands, hit super high, super heavy at times, and I again had like a million chances and it just didn't go my way in those kinds of big moments."

Meanwhile, Boisson was ecstatic following the victory. "I'm not sure what to say. Playing on this court, with this atmosphere, was amazing," she said.

"I gave my all and in the end I won, which is just incredible. I hope I'm going to win it all." She will now face Russia's 18-year-old star Mirra Andreeva in the quarter-finals on Wednesday.
