Lydia Ko claimed her 18th LPGA Tour title with a superb final round at the BMW Championship in South Korea.
It's Ko's third victory in the last 18 months - and she showed all of her class and experience to prevail in the country of her birth.
She started the day one shot behind Thai 19-year-old Atthaya Thitikul, but a majestic closing seven-under 65 at Oak Valley Country Club lifted her to 21-under overall, four clear of America's Andrea Lee, with Hye-Jin Choi and Hye Joo Kim a further shot back in a tie for third on 16-under.
Thitikul signed off on 13-under after finishing with a two-over-par 74.
New Zealander Ko said afterwrads: "It's great to be back in the winner's circle and it means a lot to win in Korea - the place that I'm born. It makes it very special."
Leona Maguire carded her third level-par 72 of the tournament to sign off on one-under, with Stephanie Meadow on nine-over following a second consecutive four-over 76.
