Australian Open champion Caroline Wozniacki eased past Frenchwoman Pauline Parmentier 6-0, 6-3 in the French Open third round on Friday while fourth seed Elina Svitolina was knocked out.
The second seed Wozniacki, a quarter-finalist in Paris last year, will face Daria Kasatkina for a place in the last eight after the Russian beat Maria Sakkari 6-1, 1-6, 6-3.
US Open runner-up Madison Keys saw off Japanese 21st seed Naomi Osaka 6-1, 7-6 (9/7), setting up a last-16 tie with 31st seed Mihaela Buzarnescu.
Buzarnescu, a 30-year-old Romanian with a doctorate in sports sciences who had never won a Grand Slam match before this week, downed Ukraine’s fourth seed Elina Svitolina with a shock 6-3, 7-5 victory.
The 13th seed Keys missed a match point on her own serve in the second set, but then saved two set points in a tie-break before an Osaka double fault sent the American through.
Russian youngster Daria Kasatkina overcame a second-set blip to see off Maria Sakkari 6-1, 1-6, 6-3, while Kazakhstan’s Yulia Putintseva, a quarter-finalist in 2016, beat China’s Wang Qiang 1-6, 7-5, 6-4.
