The other four seeded women on Wednesday's schedule also advanced to the tournament quarterfinals.

Seventh-seeded Peng Shuai didn't face a break point in a 6-2, 6-1 victory over Nudnida Luangnam and eighth-seeded Alize Cornet advanced to a quarterfinal pairing against Cirstea when Olga Govortsova retired due to illness. Cornet won the first set 6-4 and Govortsova was unable to come out for the second set.
