Maria Sakkari dispatched 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 tight 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.
“I am speechless, it is a dream come true,” said the 25-year-old. “It is a very nice feeling.”
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.
“I never imagined I would be standing here one day,” said Krejcikova.
“Already for me this is something I have never dreamed of. I was really playing a great match and Coco is incredible – she is 17, it’s amazing.”
It means all four semi-finalists in Paris are into the last four at a Grand Slam for the first time.
Anastasia Pavlyuchenkova will face Tamara Zidansek in the other semi-final on Thursday.
