South Korea's Young Kim fired a four-under par 68 in Sunday's final round to capture the 1.3 million-dollar LPGA Corning Classic by three strokes.
Kim finished 72 holes on 20-under par 268 with compatriot Mi Hyun Kim and American Paula Creamer on 271. American Beth Bader and Korean In-Kyung Kim shared fourth on 272.
The winner birdied four of the first seven holes to take command, but Kim slipped back with two bogeys to finish the front nine. Kim regained the lead with a birdie at the 14th and sank another at 17 to seize a two-stroke edge.
That forced playing partners Creamer and Bader, her nearest rivals all day, into taking chances that failed. Creamer made a bogey and Bader a double bogey to fall back.
Bader began with bogeys at the first and third holes. She bounced back with birdies at the fifth and sixth holes and another to end the front nine but made only one, at the 12th, on the back nine.
Creamer birdied three of the first five holes to challenge Kim for the early lead but a double-bogey at six dropped her back. Creamer charged again with birdies at eight and 12 but a bogey at 14 dropped her back for good.
Korean Seon Hwa Lee, Japan's Ai Miyazato and American Diana D'Alessio shared sixth on 273.
