Feng moved past Choi Na-yeon for the No. 3 spot, while Park took the sixth spot from Ai Miyazato. There was no LPGA tournament last week. Changes in the rankings reflect points earned in previous events being downgraded.
The tour, which had the Sept. 20-23 Navistar LPGA Classic as its most recent tournament, begins an Asian swing starting Oct. 11 in Malaysia.
Yani Tseng, even with a relative off-year for her, retained the No. 1 ranking for an 86th week. Only Lorena Ochoa (158 weeks) was No. 1 for a longer period. Tseng has a ranking points average of 13.08.
Stacy Lewis moved to No. 2 after winning the Navistar and is still there with an average of 8.66. Feng's average is 8.31, while Choi, in fourth, comes in at 8.24.
Jiyai Shin (7.62) remains in fifth, while Park's average of 7.32 makes her No. 6 and Miyazato's average is 7.26.
Suzann Pettersen comes in eighth at 6.59, while Mika Miyazato (6.36) take the ninth spot and Ahn Sun-ju (6.11) is No. 10.
