Of course, Annika Sorenstam was No. 1 again. She was followed by Lorena Ochoa, Karrie Webb, Cristie Kerr, Juli Inkster, Paula Creamer, Jang, Wie, Ai Miyazato and Pat Hurst to round out the top 10.
Fudoh, Ohyama, Mi Hyun Kim, Pak, Han, Seon-Hwa Lee, Natalie Gulbis, Gustafson, Jee Young Lee and Steinhauer made up places 11-20.
