Vera Zvonareva and Francesca Schiavone were both eliminated in the third round of the Dubai Championships on Thursday.
Alisa Kleybanova beat Russian teammate Zvonareva 6-3, 6-2, while Svetlana Kuznetsova defeated Schiavone 1-6, 6-0, 7-5.
Samantha Stosur of Australia also reached the quarterfinals, beating Swiss veteran Patty Schnyder 6-3, 6-4, while Agnieszka Radwanska of Poland defeated Marion Bartoli of France 6-3, 6-2 and Shahar Peer if Israel overcame a sluggish start to beat Yanina Wickmayer of Belgium 3-6, 6-4, 6-1.
The highly anticipated match between Schiavone and Kuznetsova lacked the drama of their Australian Open encounter in Melbourne which lasted nearly five hours and was the longest women's Grand Slam singles match in the Open era. Schiavone won that fourth-round match.
