Inbee Park became the second woman in LPGA Tour history to win the first three majors of the year, and that helped her expand her lead atop the latest women's world rankings.
Park has won three majors and six events in all this season. Her win Sunday at the U.S. Women's Open was her third straight LPGA Tour victory. Those three wins have helped her more than quadruple her lead atop the rankings.
Entering the LPGA Championship, Park led Stacy Lewis by 1.16 average points. After three straight wins, two of which were majors, Park stands 4.98 average points clear of Lewis.
Behind Park and Lewis, the next four spots were unchanged with No. 3 Suzann Pettersen followed by Na Yeon Choi, So Yeon Ryu and Shanshan Feng.
Karrie Webb inched up one to seventh and that bumped Yani Tseng down one to eighth. Jiyai Shin was ninth again this week.
I.K. Kim, who was runner-up to Park at the U.S. Women's Open, jumped five places to 10th. That move pushed Ai Miyazato, Cristie Kerr and Catriona Matthew down one place apiece. Paula Creamer remained 14th, while Mika Miyazato slip a pair to 15th.
Amateur star Lydia Ko and Ariya Jutanugarn stayed put at 16 and 17, while Angela Stanford jumped two to 18th. Lizette Salas remained No. 19 and Amy Yang was down two to 20th.
