New Zealand golfer Lydia Ko is a big 13 strokes behind the leader after the third round of the Women's British Open at Woburn.
The world No.1 finished down the field on three under par overall after a three under round of 69.
Ko looked as if she might launch a charge when she posted six birdies in nine holes from the eighth but the double bogey at the last stopped her in her tracks.
Thailand's Ariya Jutanugarn holds a two-stroke lead at the fourth and penultimate major of the season, boosting her hopes of landing a fourth victory of the season with a faultless 66.
Jutanugarn, who reeled off three LPGA Tour wins in a row earlier in the year, fired six birdies to finish on 16 under.
South Korean Lee Mi-rim (69), who led after the opening two days, was in second place on 202, three ahead of American Mo Martin (69).
