No major changes in women's rankings

Chie Arimura moved up to 16th in the women's world rankings this week, but otherwise there were no major changes.

World No. 1 Yani Tseng still holds a large advantage over U.S. Women's Open champion Na Yeon Choi. Stacy Lewis, Ai Miyazato, LPGA Championship winner Shanshan Feng, Suzann Pettersen, Amy Yang, Sun Ju Ahn, Cristie Kerr and Jiyai Shin held their spots from third through 10th, respectively.

I.K. Kim, Sun Young Yoo, Paula Creamer, Azahara Munoz and Brittany Lincicome are still 11th through 15th.

Arimura's rise bumped Mika Miyazato, Ji-Hee Lee and Angela Stanford down one spot each. So Yeon Ryu rounds out the top 20.
