Suzann Pettersen continues to close the gap between her and No. 1-ranked Inbee Park as the Norwegian prepares to defend her title at this week's Sunrise LPGA Taiwan Championship.
Pettersen finished in a tie for third place at the LPGA KEB: HanaBank Championship in South Korea over the weekend while Park tied for 28th.
Park now has 11.98 points, less than a full point ahead of Pettersen (11.09).
American Stacy Lewis remains No. 3, followed by New Zealand amateur Lydia Ko and South Korea's So Yeon Ryu, who dropped one spot.
South Korea's Amy Yang, who won Sunday's event in a playoff over countrywoman Hee Kyung Seo, jumped nine spots to No. 18. Seo was the biggest mover of the week, climbing 17 spots to No. 37.
Yani Tseng, who began the year ranked No. 1, has slid all the way to No. 25. She won the inaugural Sunrise LPGA Taiwan Championship in 2011, and finished third in her home country last year.
"I feel pretty excited," said Tseng. "It's been a year and I love to see all the fans out there supporting me and the LPGA. It's such a great event and I know the course pretty well. It's pretty fun having the players come to Taiwan and show them where my home town is. I'm very happy to go back there to play in front of my country."
