(Reuters) - Lydia Ko had her putter to thank for keeping her in the hunt for a third straight major on Friday after the world number one shot a one-under 70 that left her a stroke behind leaders Brooke Henderson and Lee Mi-rim at the KMPG Women’s PGA Championship. Ko scrambled her way to eight pars and a birdie on the back nine of her second round at Sahalee Country Club outside Seattle. South Korean Lee had a 69 while Canadian Henderson had a two-over 73.
