Park In-bee (AP-Yonhap News)

South Korean golfer Park In-bee climbed to No. 3 in the world after an improbable victory last weekend.

Park moved up a spot to trade places with Stacy Lewis of the U.S. at No. 3 in the latest women’s world rankings released Tuesday.

Park, the 2012 LPGA Tour money winner, captured the Honda LPGA Thailand last Sunday for her first win of this season.

She fired a five-under 67 in the final round with six birdies and a bogey.

Ariya Jutanugarn, a Thai teenager, blew a two-shot lead over Park on the par-5 18th with a disastrous triple bogey.

Park, who had finished her round in a group ahead of Jutanugarn, watched from the clubhouse as Jutanugarn missed a short putt for a double bogey that would have set up a playoff.

Yani Tseng of Taiwan remained at No. 1 for the 107th week, followed by South Korean Choi Na-yeon. Shin Ji-yai, at No. 6, and Ryu So-yeon, ranked eighth, are the two other South Koreans in the top 10.

South Koreans have won the first two LPGA tournaments this season. (Yonhap News)
