Iga Swiatek is the only top-10 player remaining in the women's singles draw at the French Open after Maria Sakkari beat Sofia Kenin in straight sets.
Sakkari moved into the quarter-finals of a grand slam for the first time with an emphatic 6-1 6-3 defeat of last year's runner-up Kenin on Monday.
Greek 17th seed Sakkari will face either defending champion Swiatek or Marta Kostyuk in the last eight at Roland Garros.
The 25-year-old is the first Greek woman to reach a grand slam quarter-final in the Open Era.
World number four Kenin made 32 unforced errors and racked up nine double faults in a one-sided contest on Court Suzanne-Lenglen.
Sakkari broke the 2020 Australian Open champion, beaten by Swiatek in the 2020 final, six times and lost just four points on her first serve to march into the last eight.
Coco Gauff, 17, earlier became the youngest grand slam quarter-finalist for 15 years by beating Ons Jabeur 6-3 6-1, while Barbora Krejcikova thrashed Sloane Stephens 6-2 6-0 in Paris.
