INCHEON (REUTERS) - American Lexi Thompson took advantage of a faltering final round by world No. 2 Lydia Ko to claim the US$2 million LPGA KEB Hana Bank Championship by one shot in Incheon, South Korea, on Sunday.
The world No. 5 fired a final round three-under 69 at the Sky 72 Club, west of Seoul, for a total of 273 to leapfrog joint overnight leader Ko (72) and claim her sixth LPGA Tour title and second of the year.
"Getting the win, it means so much," Thompson said at the trophy presentation.
Ko's difficult day was complete when she missed an eight foot birdie putt on the last that would have allowed her to reclaim the world No. 1 ranking from South Korean Park In Bee.
Instead she finished in a share of fourth.
Former world No. 1 Tseng Ya-ni (68), who has fallen outside the top 50, continued her return to form by finishing joint second with South Korean Park Sung Hyun (71), who struggled with a cold putter on the back nine on Sunday.
South Korean Amy Yang struck a joint course record 62 to vault up the leaderboard to claim a share of fourth 275, alongside Ko and American Gerina Piller (67).
