Entering the French Open, 22-year-old Lois Boisson had never played a Grand Slam main-draw match. On Monday, the World No. 361 stunned No. 3 seed Jessica Pegula in three sets on Court Phillipe-Chatrier, becoming the first French woman to reach the Roland-Garros quarterfinal since 2017.

There are hefty prizes up for grabs at Roland Garros this year, with more than $64 million set to be handed out to French Open participants. The second of the year's four Grand Slam events, the clay-court tournament is one of the most anticipated events of the year.
