World number 361 Lois Boisson continued her fairytale run at the French Open with a straight-set quarter-final victory over sixth seed Mirra Andreeva.
Boisson, who entered the draw as a wildcard, has now beaten three seeds en route to the semi-finals following her 7-6 (8-6) 6-3 triumph on a packed Court Philippe Chatrier.
The Frenchwoman was set to be a wildcard at Roland Garros last year but had to withdraw after tearing an anterior cruciate ligament in her knee just a week before the clay-court Grand Slam was due to begin.
But 12 months on, she becomes the first player in the Open era to reach the women's singles semi-finals at the French Open as a wildcard, and the first French semi-finalist since Marion Bartoli in 2011.
World number two Coco Gauff awaits Boisson in the last four after the American came from a set down to beat compatriot Madison Keys 6-7 (6-8) 6-4 6-1 earlier on Wednesday.
