Wozniacki rolls on as Svitolina exits French Open

Caroline Wozniacki raced into the fourth round of the French Open with a crushing victory over home hope Pauline Parmentier.

The reigning Australian Open champion needed just an hour and 18 minutes to dismiss her 74th-ranked French opponent on Friday.

The feeling among the locals was that Parmentier, the world No.75, had the tools to trouble the No.2 seed and maybe even send her packing.

Instead the 32-year-old found herself facing the dreaded double bagel with Danish star Wozniacki up 6-0 5-0 after only an hour.

At deuce Parmentier found a winner to earn a game point and raised her arms in mock celebration.

She actually went on to win the next three games, but it was only delaying the inevitable as Dane Wozniacki went through 6-0 6-3.

"I feel pretty good. I think I played some solid tennis, and I'm happy to be through to the fourth round here again," said Wozniacki, who now plays Russia's Daria Kasatkina.

"You know, it gets harder and harder with every match. I'm happy to be here."

American 13th seed Madison Keys overcame a second-set wobble to beat Japan's Naomi Osaka 6-1 7-6 (7-5) and set up a last-16 clash with Romanian Mihaela Buzarnescu.

A match between two of the biggest hitters on the WTA Tour failed to really catch fire on a cool and half-empty Suzanne Lenglen Court with Keys helped on her way to the first set by a succession of wild errors from Osaka.

Keys will next face Buzarnescu, who stunned fourth-seeded Ukrainian Elina Svitolina 6-3 7-5 on Friday.

The 23-year-old Svitolina had been tipped as one of the potential winners this year after winning the Italian Open, but she never found her groove on Court One.

She dropped serve five times and made 29 unforced errors, bowing out on the first match point when she buried another forehand into the net.

Meanwhile, employing a vicious topspin forehand modelled on her idol Rafael Nadal's weapon-of-choice, Kasatkina recovered from a mid-match blip in her match to reach the last-16, defeating Greece's Maria Sakkari 6-1 1-6 6-3.

After reaching the fourth round for the first time, 2014 junior champion Kasatkina was quizzed about what she had learnt from French Open legend Nadal.

"A lot, a topspin forehand, movement on the court and fighting spirit for sure. Because I watched Rafa a lot, I started to spin the ball," the 21-year-old, who flashed 11 forehand winners compared to just two from her backhand, said.

A heavy spell of rain at Roland Garros meant play was later cancelled for the day with Petra Kvitova, the eighth seed and 10th seed Sloane Stephens unable to start their matches.
