Inbee Park's victory Sunday at the Evian Masters moved her up six spots into the top 20 in this week's world rankings.
Park collected her second LPGA Tour win after her 2008 U.S. Women's Open victory. She came in 15th this week in the rankings.
Yani Tseng remains in first, but her slump continued. Tseng missed the cut in France.
Stacy Lewis finished in a tie for second behind Park and switched places with Na Yeon Choi for second. Shanshan Feng, who won this year's LPGA Championship, shared fourth at the Evian Masters, and moved to fourth, followed by Ai Miyazato, who fell one spot.
Suzann Pettersen and Amy Yang remained in sixth and seventh. Cristie Kerr inched up one to No. 8, while Sun Ju Ahn slid to ninth. Jiyai Shin completed the top 10.
I.K. Kim held on to 11th as Paula Creamer rose a spot to 12th. Sun Young Yoo fell to 13, followed by Azahara Munoz and Park. Brittany Lincicome, Chie Arimura and Mika Miyazato each dipped a place and Karrie Webb, who tied for second with Lewis, shot up five to No. 19. Ji-Hee Lee fell two to No. 20.
