Top 10 shake-up in women's tennis

ST. PETERSBURG, Fla., Nov. 10 (UPI) -- The WTA-season-ending Sony Ericsson Championships in Qatar, won by Venus Williams, shook up the Top 10 of the women's world tennis rankings.

The elite tournament, which invites just eight top players, concluded Sunday with Williams' 6-7 (5-7), 6-0, 6-2 victory over Vera Zvonareva. The win moved Williams from eighth to sixth in the world while Zvonareva improved from ninth to seventh.

The only two ranking positions not to change in the Top 10 released Monday were No. 1 Jelena Jankovic and 10th-rated Agnieszka Radwanska.

Serena Williams moved from third to second, switching places with Dinara Safina, and Elena Dementieva jumped one spot to fourth, knocking Ana Ivanovic to fifth.

Svetlana Kuznetsova dropped one spot to eighth and Maria Sharapova, whose play has been limited by injury and who withdrew prior to the Sony Ericsson Championships, fell from sixth to ninth.

The next scheduled WTA events are to begin Jan. 5 in Auckland, New Zealand, and Brisbane, Australia, two weeks before the Australian Open.
