Kim Sei-young claimed her fifth career title on the LPGA Tour after defeating Carlota Ciganda in a play-off for the Meijer LPGA Classic on Sunday.
The South Korean, who started the day one stroke behind overnight leaders Lexi Thompson and Chun In-gee, shot a three-under-par 68 to take her overall score to 17 under.
She was joined by an in-form Ciganda (67) atop the leaderboard after the Spaniard went bogey-less in an impressive final round, setting up a play-off finish in Grand Rapids, Michigan.
But Ciganda collapsed on the first play-off hole, carding a bogey while Kim birdied the par-four 18th to take the win at the Blythefield Country Club.
The title was Kim's second of 2016 after the 23-year-old's five-stroke victory at the JTBC Founders Cup in March.
Ciganda meanwhile is still without a win on the LPGA Tour, falling for a second time in a play-off after losing out to Lydia Ko at the CME Group Tour Championship in 2014.
Chun (71) finished two strokes behind the leaders to be outright third, while world number one Ko (68) and Thompson (72) were one shot behind tied for fourth.
Brooke Henderson (71), fresh off her Women's PGA Championship triumph last week, finished tied for 21st after a difficult final two rounds.
