Yani Tseng remained in first, followed by Na Yeon Choi and Suzann Pettersen. Ai Miyazato, who won the LPGA LOTTE Championship last week, inched up one to fourth this week, while Cristie Kerr dipped one to fifth.

Lewis came in sixth and I.K. Kim held on to No. 7. Jiyai Shin sank two to eighth and Sun Ju Ahn fell one place to nine. Paula Creamer once again rounded out the top 10.

Brittany Lincicome and Shanshan Feng switched spots this week with Lincicome in 11th and Feng down to 12th. Amy Yang kept hold of No. 13 and Sun Young Yoo rose one to 14th. Angela Stanford slipped a spot to 15th.

Chie Arimura climbed one place to 16th with Ji-Hee one worse at No. 17. So Yeon Ryu held steady at 18th and Karrie Webb and Catriona Matthew traded places this week with the Scot in 20th.

Thompson, who fought on the back nine to make it a tough battle for Lewis, flew up 14 places to No. 24. The 17-year-old, who won last year's Navistar LPGA Classic, is now one spot ahead of Michelle Wie.
