Sloane Stephens celebrates

Madison Keys has reached her first French Open quarter-final after beating Romania’s Mihaela Buzarnescu 6-1 6-4.

The 13th seed and former US Open finalist dominated the first set before sealing her passage into the last eight with an ace on her third match point.

Keys’ fellow American Sloane Stephens was also in fine form, overcoming Anett Kontaveit 6-2 6-0.

“I was really pleased to get out and play some good tennis,” said the US Open champion.

Stephens will face the winner of second seed Caroline Wozniacki’s fourth-round match against Daria Kasatkina.

Keys, meanwhile, will play Yulia Putintseva after she beat Barbora Strycova 6-4 6-3.
