Paris: Shelby Rogers produced one of the biggest shocks at this year’s French Open when she knocked out twice Wimbledon champion and 10th seed Petra Kvitova in the third round yesterday.
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.
Agnieszka Radwanska survived a second-set wobble to qualify for the last 16 with a 6-2 6-7 (6) 6-2 victory over Czech Barbora Strycova.
The second-seeded Pole, looking to win her first grand slam title, next faces 19th-seeded American Sloane Stephens or Bulgarian Tsvetana Pironkova.
Following an early trade of breaks, Radwanska pulled away, winning four consecutive games to bag the opening set before opening a 3-0 lead in the second.
But she completely lost her composure and world number 33 Strycova reeled off five straight games on the way to taking the tiebreak.
Order was restored in the decider, however, as Radwanska broke four times to wrap up the win.
Spanish fourth seed and last year’s Wimbledon runner-up Garbine Muguruza won the last nine games to knock out Belgium’s Yanina Wickmayer 6-3, 6-0.
Muguruza, a quarter-finalist in the last two years, next faces 2009 champion Svetlana Kuznetsova who beat Russian Fed Cup teammate Anastasia Pavlychenkova 6-1, 6-4.
Romanian sixth seed Simona Halep, the runner-up to Maria Sharapova in 2014, needed three sets to see off 18-year-old Japanese player Naomi Osaka 4-6, 6-2, 6-3.
Halep, 24, next faces 2010 finalist Sam Stosur who defeated 2015 runner-up Lucie Safarova of the Czech Republic 6-3, 6-7 (0/7), 7-5.
