Michie Oba shot a 7-under-par 65 Saturday to move into a tie for the lead with Yoko Yamagishi and England's Samantha Head after the second round of the Miyagi TV Cup Dunlop Ladies Open.

Oba, who has won four times in her 10-year career on the Japan LPGA tour, rebounded from an opening-hole bogey to make eight birdies on her way to an 8-under 136 total at Rifu Golf Club in Miyagi Prefecture.
