Natsuka Hori ran away with the Earth Mondahmin Cup on Sunday, starting with the lead and posting a 5-under-par 67 to wrap up her second career title.
Hori, who will turn 21 on Thursday, wrapped up the proceedings at 21-under-par 267. She finished with an eagle and three birdies to seal victory by eight strokes at Camellia Hills Country Club. Hori's ¥25.2 million in prize money shot her up to second place on the season earnings table.
Last year's top money winner, Jeon Mi-jeong of South Korea, was all alone in second place after a 1-over-par final round left her at 13-under for the week. Asako Fujimoto and South Korea's Lee Bo-mee were a stroke further back in a tie for third at 12-under par.
Rikako Morita, who has three victories on tour this season, still leads the money rankings by a wide margin despite finishing 14th.
