PARIS, May 30 (UPI) -- No. 1-ranked Victoria Azarenka dropped just two games and Agnieszka Radwanska defeated Venus Williams in Wednesday's second-round play at the French Open.
Azarenka, who struggled in her first-round match, rolled over Dinah Pfizenmaier 6-1, 6-1. She had just nine winners but also just 11 unforced errors. Pfizenmaier matched the nine winners but hampered herself with 29 unforced errors.
Azarenka won three-quarters of the points on serve, saving both break points she faced.
Radwanska, seeded third, took out Williams 6-2, 6-3, closing the match with her fifth service break. Radwanska had just six unforced errors Wednesday while Williams had 33. Radwanska won half the points when Williams served.

Eighth-seeded Marion Bartoli joined the Williams sisters on the sidelines after a 6-2, 3-6, 6-3 loss to Petra Martic. Bartoli had 14 double faults.
No. 6-seeded Samantha Stosur easily got past Irina Falconi 6-1, 6-4 without dropping serve, and 15th-seeded Dominika Cibulkova sailed past Vania King 6-0, 6-2, taking more than two-thirds of the points.
No. 10-seeded Angelique Kerber was down an early break 1-2 against Olga Govortsova in Wednesday's final women's singles match when play was suspended by rain.
