Defending champion Stan Wawrinka beat Viktor Troicki in four sets to reach the last eight of the French Open.
The Swiss third seed won 7-6 (7-5) 6-7 (7-9) 6-3 6-2 and will face Albert Ramos-Vinolas in the quarter-finals after the Spaniard knocked out eighth seed Milos Raonic 6-2 6-4 6-4.
Fourth seed Garbine Muguruza progressed with a 6-3 6-4 win against Russia’s 2009 champion Svetlana Kuznetsova.
The 22-year-old Spaniard will face American Shelby Rogers next.
Rogers, ranked 108th in the world, reached her first Grand Slam quarter-final by beating Romanian 24th seed Irina-Camelia Begu 6-3 6-4.
Rogers is 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.
“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.
Ramos-Vinolas’ win ensures at least one Spaniard will play in the men’s quarter-finals at Roland-Garros for the 20th year running.
The 28-year-old left-hander, who has never been past the second round in 18 appearances in the four majors, broke Raonic five times and only lost serve once.
“I have no words to explain how I feel,” said the world number 55. “It was four years in a row losing in the first round.”
