Overnight co-leader Ikuyo Shiotani birdied the first four holes of the final round Sunday and held on over a bumpy back nine for a 3-under-par 69 and a one-stroke victory in the Golf 5 Ladies tournament.
Shiotani, who started the day even with Hikaru Kobayashi at 7-under, sprinted out to a four-stroke lead at the turn at Mizunami Country Club and then stretched it to six strokes with an eagle on No. 10.
Mikiyo Nishizuka shot 69 for the second straight day to climb into third place at 7-under 209.
