The New Zealand golfer Lydia Ko is in striking range of winning her first tournament of the year at the LPGA's Swinging Skirts Classic in San Francisco.
The 17-year-old will begin her final round in second place on 9 under par, just one shot adrift of American leader Stacy Lewis.
The pair will resume their duel just after 8:30 this morning and Ko says staying smart on the Lake Merced greens is the key to claiming the title.
