Korea's Inbee Park stretched her lead as the No. 1 player in the Rolex Rankings with her fifth victory of 2013 at the Walmart NW Arkansas Championship on Sunday.
Park (12.04 points) now leads American Stacy Lewis by 3.52 points. Lewis sits at 8.52 points, and there was no change among the top five golfers as Suzann Pettersen, Na Yeon Choi and So Yeon Ryu are tightly packed behind Lewis.
The only change among the Top 10 was the continued slide of former No. 1 player Yani Tseng, who fell to No. 7 after being passed by Shanshan Feng.
Park's five victories this season on the LPGA Tour include wins in the first two majors this season, the Kraft Nabisco Championship and the LPGA Championship.
She will try for the third straight major victory in the U.S. Women's Open, which starts Thursday at Sebonack Golf Club in Southampton, N.Y.
Park will try to match Babe Zaharias (1950) as the only LPGA player to win the first three majors in a season.
"This week is a good preparation week for me as I go into the U.S. Women's Open," Park said. "I've won the last two weeks and there's a lot of emotions, so I'm just going to try to calm down myself a lot and try to play the course.
"I'm sure the course is going to make me concentrate, so I'm really looking forward to playing there and not to think about any kind of history or trying to break somebody's record."
