Yani Tseng won the latest LPGA tournament and remains ranked No. 1 in the world in women\'s golf while former No. 1 Ai Miyazato moves up in the rankings. Tseng was a one-stroke victor Sunday at the RR Donnelley LPGA Founders Cup tournament in Phoenix. It was her 24th professional win and 14th in the last 15 months. She has been ranked at the top of women\'s golf for 57 weeks. Only Lorena Ochoa (158 weeks) and Annika Sorenstam (60) were No. 1 longer. Tseng is likely to pass Sorenstam\'s mark as her ranking points average of 17.27 is well ahead of No. 2 Choi Na-yeon\'s 9.11 and No. 3 Suzann Pettersen is another point back at 8.11. Cristie Kerr is fourth at 7.90 followed by fifth-ranked Ahn Sun-ju (6.79) and No. 6 Paula Creamer (6.60). Miyazato, who tied Choi for second in Phoenix, goes from ninth to No. 7 this week, with an average of 6.41. That forces Jiyai Shin (6.36) down one place to eighth and Stacey Lewis (6.18) down one to ninth. Brittany Lincicome (5.85) remains in the No. 10 spot.
