GULLANE, Scotland (AP) Thailand's Ariya Jutanugarn hit six birdies in a final round 5-under 66 to win the Ladies Scottish Open by one shot on Sunday.
The 22-year-old Jutanugarn held off the challenge of Australian Minjee Lee at Gullane to claim her 10th LPGA title and third this year.
Jutanugarn finished on 13-under 271 to move top of the world rankings, ahead of South Koreans Inbee Park and Sung Hyun Park.
''It means a lot to me, it's like my dream come true,'' the Bangkok-born Jutanugarn told lpga.com.
''I told my caddie this week, `I want to win on a links course one time in my life,' and I did it so (I feel) pretty good.''
Runner-up Lee remained in close pursuit of Jutanugarn throughout Sunday but was unable to make up a one-shot overnight deficit.
Lee produced a bogey-free 66 but couldn't do enough after her third-round 71.
Jutanugarn has also won the Kingsmill Championship and U.S. Women's Open this year.
South Koreans Jin Young Ko (67) and Haeji Kang (69) finished tied for third on 8 under, while their compatriot Amy Yang dropped to joint fifth.
Yang, who shared the overnight lead with Jutanugarn, carded a 1-over 72 to finish tied for fifth with Spaniard Carlota Ciganda.
