Jutanugarn leads Women's British Open

Thailand's Ariya Jutanugarn boosted her hopes of landing a fourth victory of the season by surging into a two-stroke lead after the third round of the Women's British Open on Saturday.

Jutanugarn, who reeled off three LPGA Tour wins in a row earlier in the year, fired six birdies in a faultless 66 to finish on 16-under-par 200 in the fourth and penultimate major of the season at Woburn.

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).

Veteran Australian Karrie Webb sits in a four-way tie for sixth after carding a two-under par 70 to be eight-under par overall.

New Zealand's world No.1 Lydia Ko finished down the field on three-under 213.

Ko looked as if she might launch a charge when she posted six birdies in nine holes from the eighth but a double-bogey at the last stopped her in her tracks.

Britain's Charley Hull, a member at Woburn, watched her title hopes go up in smoke after ballooning to a triple-bogey seven on the first hole. The 20-year-old ended up returning a 75 for 214.
