LOS ANGELES: Kim Sei-young sprinted clear in the final round of the Marathon Classic for a two-stroke victory over Lexi Thompson in Sylvania, Ohio, on Sunday.
After starting the day with a one-shot lead, Kim built a tournament-winning advantage with five straight birdies mid-round at Highland Meadows.
The South Korean coasted home from there to card six-under-par 65 and clinch her ninth LPGA Tour victory.
The 26-year-old tied Choi Na-yeon for the fourth most wins by a Korean player in LPGA history, behind Pak Se-ri (25), Park In-bee (19) and Shin Ji-yai (11).
Kim finished at 22-under 262, while American Thompson (66) eagled the final hole for second place on 20 under.
Korean players have now won nine LPGA tournaments this year.
