Stacy Lewis returns this week to the scene of her first title, at the Kraft Nabisco Championship in 2011, but this time she'll pursue a major crown with the world No. 1 ranking next to her name. Lewis said the first thing on her mind this week will be trying to win a tournament, rather than holding on to that coveted top ranking. "There are so many things that I can't control," the Texas native said. "I can't control how Yani (Tseng) plays, how In-bee Park plays. "If they go out and play better than me, then I lose the No. 1 ranking.

Stacy Lewis claimed the World No. 1 women's golf ranking by firing a final-round eight-under par 64 to beat Japan's Ai Miyazato by three strokes on Sunday at the $1.5 million LPGA Founders Cup. The 28-year-old American knocked 2012 Founders Cup champion Yani Tseng of Taiwan from atop the rankings after a stay of 109 weeks with the victory and Tseng finishing in a share of 59th place, 19 strokes off the pace.

Ai Miyazato fired a five-under par 67 and was aided by a penalty on American Stacy Lewis on her way to seizing a four-stroke lead after the third round of the LPGA Founders Cup on Saturday. Japan's Miyazato, who seeks her 10th career LPGA title, finished 54 holes at the $1.5 million event on 19-under 197 with Lewis, who could claim the World No. 1 ranking with a victory, and South Korean Jee Young Lee third on 201.

World number two Choi Na-Yeon emerged from a two-and-a-half-hour storm delay to birdie the last hole and dramatically snatch a share of the HSBC Women's Champions lead alongside Stacy Lewis on Saturday. Choi, who is eyeing the number one ranking of Taiwan's Tseng Yani, holed a 10-footer in front of a big gallery on the damp 18th green to card five-under-par 67 for a total of 14-under 202 at Singapore's par-72 Sentosa Golf Club.
