Dubai: Caroline Wozniacki moved within one victory of regaining the No. 1 ranking after beating Japan's Ayumi Morita 6-1, 6-0 to reach the quarterfinals of the Dubai Championships on Thursday.
The 20-year-old Dane, who lost the top spot to Kim Clijsters on Monday, was never seriously challenged by the 57th-ranked Japanese qualifier. She now must beat Shahar Peer of Israel to return to No. 1. Wozniacki lost to Peer in the third round last year.
In earlier matches, U.S. Open finalist Vera Zvonareva and French Open champion Francesca Schiavone were both eliminated in the third round.
