Shelby Rogers, the world number 108 from USA, reached her first Grand Slam quarter-final on Sunday with a 6-3, 6-4 win over Romanian 25th seed Irina Camelia-Begu.
Rogers is just the ninth woman outside of the top 100 to make the last eight in Paris since 1983.
“It’s incredible and I’m really happy that it didn’t start raining,” said Rogers, who broke down in tears after the match and had to borrow a handkerchief from television interviewer Marion Bartoli, the former Wimbledon champion.
“I always dreamed of this when I was a little girl in Charleston but never really thought I would reach the quarter-finals in Paris.”
Rogers has now beaten three seeds in her run at Roland Garros, having seen off 17th seed Karolina Pliskova in the first round and 10th seed Petra Kvitova in the last 32.
She will face Spanish fourth seed Garbine Muguruza for a place in the semi-finals.
