DAYTONA BEACH, Fla., Oct. 10 (UPI) -- Agnieszka Radwanska and Andrea Petkovic both jumped into the Top 10 in the updated world women's tennis rankings Monday.
Radwanska defeated Petkovic 7-5, 0-6, 6-4 in Sunday's final of the China Open. That boosted Radwanska from 12th to No. 8, matching her career best. Petkovic's move from 11th to ninth gives her her highest ranking.
Caroline Wozniacki, who was unable to defend 2010 tournament titles the last two weeks, is nonetheless No. 1 for a 53rd week. That total is ninth-best all time. She has a way to go to reach Lindsay Davenport, who is eighth on the list after 98 weeks at No. 1. Steffi Graf holds the women's record at 377 weeks at the top spot.
Wozniacki's current streak of 35 consecutive weeks at No. 1 is 17th longest. Justine Henin and Davenport each had 44-week marks and are tied for 15th on that chart. Graff, at 186 weeks, also has that record.
Wozniacki has 8,005 ranking points and Maria Sharapova 6,370 for the No. 2 ranking. They are the only players to retain their ranking positions from last week.
Victoria Azarenka, with 6,190 points, goes from fourth to No. 3, tying as career high, and Petra Kvitova (5,760) is up one to a career-best fourth. Their moves reflect a drop by Vera Zvonareva (5,755) from third to fifth.
Samantha Stosur (5,455) goes from seventh to sixth, switching places with Li Na (5,425).
Radwanska has 4,940 points and Petkovic 4,604 while Kim Clijsters, down from No. 8, is 10th with 4,501.
