Fumiko Muraguchi shot a 4-under-par 68 for the second straight day in a bogey-free round on Saturday to grab a three-stroke sole lead going into the final round of the Stanley Ladies tournament.

Teeing off for the second round at Tomei Country Club three strokes off the pace, Muraguchi, seeking her first tour title in four years, birdied four holes for a 36-hole total of 8-under 136. South Korean Ko Woo Soon scattered four birdies against two bogeys en route to a 70 over the 6,447-yard course to share second place with rookie Hiromi Takesue (72) at 139.
