The 26-year-old Voskoboeva, who ousted Marion Bartoli and Flavia Pennetta to earn her date with Sharapova, beat the Russian star with soft drop shots and had the veteran chasing balls to the baseline throughout the match. She became the latest casualty of the Rogers Cup women’s draw, hours after French Open champion and sixth-seeded Li Na of China bowed out of third-round action with a 6-2, 6-4 loss to No. 10 seed Samantha Stosur of Australia. “I felt like a junior on the court,” Li said.
Also, No. 11 Andrea Petkovic of Germany also reached the quarterfinals after cruising by seventh-seeded Kvitova of the Czech Republic 6-1, 6-2. The losses by Sharapova and Li come a day after top-ranked Caroline Wozniacki was upset by No. 22 Roberta Vinci. Also gone is second-seeded Kim Clijsters, who withdrew earlier this week due to an abdominal injury, while former world No. 1 Jelena Jankovic and No. 9 seed Marion Bartoli were beaten in their opening matches.
Polish 13th seed Agnieszka Radwanska repeated last week’s victory over Zvonareva in last weekend’s Carlsbad final, coming through 6-4 7-6 (7-4) this time. Azarenka defeated Maria Jose Martinez Sanchez 6-1 6-2, and Italy’s Vinci followed up her win over Wozniacki with another impressive result as she beat former number one Ana Ivanovic 7-6 (7-3) 6-2.
