Spanish fourth seed Garbine Muguruza cantered into the fourth round of the French Open with a 6-3 6-0 thrashing of Belgium's Yanina Wickmayer today.
Muguruza converted all of her six break points to set up a meeting with either Russian 24th seed Anastasia Pavlyuchenkova 2009 champion Svetlana Kuznetsova.
After an early exchange of breaks, the 22-year-old Muguruza, a quarter-finalist at Roland Garros in the last two years, found her groove and won the last nine games on a sun-drenched Court Philippe Chatrier.
She ended the world number 54's ordeal with an exquisite backhand dropshot on her first match point.
Simona Halep avoided the embarrassment of falling victim to a teenager who calls herself "a child of the internet" as she huffed and puffed her way into the fourth round with a 4-6 6-2 6-3 win over Naomi Osaka.
It seemed as if the Romanian's name would be splashed across the World Wide Web as the latest high-profile casualty in the French capital. She was totally bamboozled in the opening set by a Japanese opponent ranked 101st in the world.
However, the sixth seed made sure she did not suffer the same fate as Australian Open champion Angelique Kerber or fifth seed Victoria Azarenka. She kept her wits about her despite a barrage of winners flying off Osaka's racket.
Australian Samantha Stosur edged out last year's runner-up Lucie Safarova 6-3 6-7(0) 7-5 to reach the fourth round.
The 32-year-old, enjoying a return to form on the European clay this year, recovered from a drubbing in the second set tiebreak to set up a last-16 clash with Romania's Simona Halep, the sixth seed.
Stosur, beaten by Italian Francesca Schiavone in the 2010 final after eliminating Serena Williams in the semis, broke at the start of the third set only for 11th seed Safarova to break back to get back to 4-4.
Former U.S. Open champion Stosur then broke in the final game to claim only her fourth victory in 15 matches against the Czech.
Shelby Rogers produced one of the biggest shocks at this year's Open when she knocked out twice Wimbledon champion and 10th seed Petra Kvitova in the third round.
The 23-year-old American, ranked 108th in the world, won 6-0 6-7(3) 6-0 to move into the last 16 of a grand slam for the first time.
Czech Kvitova's loss means four of the top 10 seeds in the women's draw have failed to reach the last 16.
Rogers will face Irina Begu of Romania next after she beat Germany's Annika Beck.
