Japan’s Miyu Yamashita produced a spectacular final-round 63 to win the Aramco Korea Championship by three shots at New Korea Country Club.
The world No 5 finished at 22-under-par 266, three clear of Czech contender Sara Kouskova, after delivering a bogey-free nine-under final round in Goyang.
Yamashita began Sunday at 13-under and quickly increased the pressure with birdies at the third, fifth and eighth holes before making another at the 10th.
Kouskova continued to challenge, but Yamashita found another gear over the closing stretch.
Three birdies in four holes strengthened her grip on the title before an eagle at the par-five 17th effectively sealed the victory.
Her 63 established a new course record, although Kouskova matched that mark with her own brilliant final-round charge to finish at 19-under.
Yamashita’s closing round featured seven birdies and an eagle without a dropped shot, completing a week in which she had led since the halfway stage.
The victory was her fourth title of 2026, continuing an outstanding season for the 25-year-old major champion.
Yani Tseng and Ginnie Ding shared third at 16-under, six shots behind the winner.
For Yamashita, the performance underlined her ability to attack when the pressure was highest. Rather than protect a narrow advantage, she produced her lowest round of the week when it mattered most.
A course record, an eagle at the penultimate hole and a three-shot victory provided an emphatic finish to another impressive week for one of the leading players in women’s golf.
