Greece's Maria Sakkari beat defending champion Iga Swiatek to reach her maiden Grand Slam semi-final at the French Open at Roland Garros.
She will face Czech Barbora Krejcikova, who won a nervy encounter with American teenager Coco Gauff 7-6 (8-6) 6-3.
Sakkari, the 17th seed, is now the highest-ranked woman in the draw after seeing off Swiatek 6-4 6-4.
Krejcikova, meanwhile, saved five set points from 17-year-old Gauff in the opener before the world number 33 went on to seal victory on her sixth match point.
It means all four semi-finalists in Paris are into the last four at a Grand Slam for the first time.
