(Reuters) - American Cristie Kerr fired a six-under 66 to share the third-round lead with South Korean Jang Ha-na at the season-ending CME Group Tour Championship on Saturday with world number one Lydia Ko lurking just two shots back.
Twice major winner Kerr overcame a bogey at the par-five first with birdies on five of the next six holes and added two more birdies on the back nine for the low round of the day at Tiburon Golf Club in Naples, Florida.
Jang, who led overnight by two in her hunt for a first LPGA title after three second-place finishes, was even par at the turn before an eventful back nine that featured an eagle, three birdies and two bogeys for 69 and her 13-under 203 total.
