Home hope Sei Young Kim secured her first LPGA Tour victory in five years at the BMW Ladies Championship in South Korea.
Having started the day with a four-stroke advantage, Kim never relinquished control, carding a five-under-par 67 with six birdies and a single bogey to finish on 24 under for the tournament.
Kim's round began with a slight stumble on the par-three third, but she quickly recovered, sinking birdies on four of the next five holes to make the turn at 33.
She cemented her lead by adding two more consecutive gains on the 14th and 15th holes, finishing with three steady pars.
This win is Kim's 13th on the LPGA Tour, ending a drought that dated back to her win at The Annika (formerly Pelican Women's Championship) in November 2020.
Nasa Hataoka also shot a 67 and finished in second place on 20 under, reducing Kim's final margin with four birdies on her last five holes, including a closing hat-trick.
A Lim Kim and Celine Boutier tied for third place, six strokes behind the winner.
Cavan's Leona Maguire never threatened to land a blow, finishing in a share of 56th place on four under after a closing 71.
