CHONAN, Chiba Pref. (Kyodo) Overnight joint leader Miho Koga pulled away from a crowded leaderboard Sunday to win the Itoen Ladies after shooting a final-round 67, highlighted by six consecutive birdies and seven in eight holes.

Koga, who shared the lead with money leader Lee Ji Hee of South Korea after two rounds, offset a bogey on the opening hole by making a 15-footer at No. 3 and her putts continued to fall, triggered by a four-footer on the fifth at Great Island Club.
