Polish second seed Radwanska needed just an hour and seven minutes to thrash Beck 6-0 6-0 on the Indian Wells hard courts.Beck had her chances – especially in the second set when she won 24 points and failed to convert four break-point opportunities – but was outclassed. Radwanska will face 22nd seed Alize Cornet in the fourth round after the Frenchwoman survived an epic against Spain's Carla Suarez Navarro to win 7-6 (7-4) 5-7 6-3. There were six breaks of serve in the deciding set before Cornet finally got through after three hours and 26 minutes. Vinci, the 13th seed, exited after a surprise 4-6 6-4 6-3 loss to Australian qualifier Casey Dellacqua. The left-handed Dellacqua only lost seven points on serve in the deciding set despite putting in just 45 per cent of first balls. Vinci's countrywoman and ninth seed Errani also departed, but her 6-3 6-3 loss to Canadian 18th seed Eugenie Bouchard was far less surprising. Bouchard meets Romanian Simona Halep next after the sixth seed overcame Czech 26th seed Lucie Safarova 6-2 4-6 6-4. American Lauren Davis awaits Dellacqua after the 20-year-old cruised past countrywoman Varvara Lepchenko 6-3 6-2. Serbian seventh seed Jelena Jankovic set up a fourth-round meeting with Caroline Wozniacki after both won. Jankovic was untroubled in a 6-3 6-2 win over Slovakian 31st seed Magdalena Rybarikova. Danish 10th seed Wozniacki, a two-time runner-up and 2011 champion at Indian Wells, got past Kazakh Yaroslava Shvedova 7-6 (9-7) 3-6 6-1.
