LOS ANGELES -- Jin Young Ko had five back-nine birdies in a 7-under 64 at demanding Wilshire Country Club for a share of the second-round lead Friday with Nasa Hataoka in the DIO Implant LA Open.
Five strokes behind first-round leader Alison Lee after a 71, the top-ranked Ko moved into position for her second victory of the season in the first of two straight LPGA Tour events in the Los Angeles area.
"My putting was so good today," Ko said. "I wasn't expecting to play really well today because in the afternoon it's always hard to play this course.
