Lewis won the tournament Sunday in Galloway, N.J., by four strokes and was only one of two Top 10 players who finished in the Top 10 in the tournament. Ai Miyazato, who is No. 4 in the world, tied for 10th.
Lewis entered the year with two LPGA wins. She picked up No. 3 on April 29 at the Mobile Bay LPGA Classic before Sunday's even-par 72 allowed her to hold the lead and win the 54-hole ShopRite event. She entered the final round with a six-stroke lead.
Yani Tseng, who with Choi Na-yeon was among those tied for 12th at the ShopRite, is No. 1 with a ranking points average of 17.01. Choi is second at 8.02 and Lewis, who was seventh a week ago, has an average of 7.61. Miyazato holds the No. 4 spot. Her average is 7.13.
Suzann Pettersen (7.11) falls two places to fifth while Ahn Sun-ju (6.78) is still sixth but Cristie Kerr slips from fifth to No. 7 with an average of 6.69. Jiyai Shin (6.22) is No. 8 after switching places with Kim In-kyung (6.18) and Shanshan Feng completes the Top 10 at 5.88.
