It was Pennetta's fourth win in six tries against Zvonareva. 

Kuznetsova, a former Top 5 player, used a lethal second serve to rally past local favorite Stosur, winning 16 of 30 second serve points. Stosur saved six of six break points in the first set, then only one the rest of the way in tumbling out of the tournament.
