American 13th seed Madison Keys reached the French Open quarter-finals for the first time on Sunday with a 6-1, 6-4 win over Romania’s Mihaela Buzarnescu.

Keys, the US Open runner-up last year, will face either Czech 26th seed Barbora Strycova or Yulia Putintseva, the 98th-ranked Kazakh, for a place in the semi-finals.

The 23-year-old American has now reached at least the last-eight of all four majors.

Stephens down Kontaveit

US Open champion Sloane Stephens reached her first Roland Garros quarter-final on Sunday, beating Estonia’s Anett Kontaveit 6-2, 6-0.

Stephens, the 10th seed, had previously made the fourth round for four successive seasons.

She will face either Australian Open champion and second seed Caroline Wozniacki or Russia’s Daria Kasatkina for a place in the semi-finals.

A clearly hobbled Kontaveit hit just five winners but 21 unforced errors in the 52-minute mismatch.

Putintseva advances

Kazakhstan’s world number 98 Yulia Putintseva reached the French Open quarter-finals for the second time on Sunday, downing Czech 26th seed Barbora Strycova 6-4, 6-3.

It will be only the 23-year-old’s second quarter-final of the year, after she had won just two matches in five clay-court tournaments this season heading into Roland Garros.
