South Korea's Kim Sei-young sunk a six-foot birdie putt on the par five 18th to win the Blue Bay LPGA in China by one stroke on Sunday.
This was the 22-year-old's third win on the tour in her first season; she shot final round a 2-under 70 for a 2-under 286 total.
Third-ranked American Stacy Lewis, countryman Kim Kaufman and Taiwan's Candie Kung all finished a stroke back.
In her sixth runner-up finish of the season, Lewis finished with a 70.
Kim started the day as co-leader with Kung at even par, she started the first hole with a birdie and bogeyed the next hole.
The next 10 holes were parred before she picked up a birdie on the par four 13th.
Lewis, who was leading by two, three-putted for bogey to allow Kim to pull into a tie.
Kim birdied the next hole to go one ahead but then on the 17th she dropped a shot to be in a three-way tie for the lead.
On the 18th, Kim, Kung and Lewis reached the green in three and after the other two missed their birdie attempts, Kim made her six-foot putt to win the tournament by one shot.
