Serena Williams, the world No. 1-ranked woman player, routed Julia Georges 6-1, 6-1 in 55 minutes. Williams committed just four unforced errors -- Georges had 20 -- and faced just one break-point situation.
Venus Williams, No. 2 in the world, took out No. 26-seeded Dominika Cibulkova 6-3, 6-4. Venus Williams won 79 percent of the points on serve and jumped on Cibulkova's second serve, winning 74 percent of those opportunities.
No. 22-seeded Justine Henin, who won the event three consecutive times before her retirement in 2008, got past Klara Zakopalova 6-3, 6-3. Henin is still having trouble getting her first serve in -- landing less than half Friday, but still only had her serve broken once.
In other second-round matches, No. 12-seeded Maria Sharapova defeated Kirsten Flipkens 6-3, 6-3; 13th-seed Marion Bartoli took out Olivia Sanchez 7-5, 6-2; 23rd-seeded Daniela Hantuchova beat Olga Govortsova 7-5, 6-3; and No. 29 Anastasia Pavlyuchenkova won 6-4, 6-1 over Jill Craybas.
