Ariya Jutanugarn has an excellent opportunity to claim her maiden major title at the Women's British Open, after opening up a two-shot lead ahead of the final round.
Jutanugarn threw away the chance to win this year's ANA Inspiration when bogeying the last three holes, but went on to claim three successive victories on the LPGA Tour in May before finishing third at the Women's PGA Championship.
And the 20-year-old Thai was in top form at Woburn on Saturday as she carded a bogey-free 66 to reach 16 under.
She will head into Sunday having surpassed long-time leader Mirim Lee, who is 14 under after a third-round 69. Mo Martin, the champion two years ago at Royal Birkdale, is five off the pace, with Catriona Matthew one further back.
"I think I know how to play under pressure," said Jutanugarn as she looked ahead to the final 18.
"The only thing I have to focus on is what is under my control."
A chip-in from the side of the eighth green provided Jutanugarn with one of her six birdies on Saturday.
World number one Lydia Ko also managed half a dozen gains as she got to three under, five of her birdies coming in the space of six holes.
In a jovial reference to the leading player in the men's game, Ko said: "Not as good as Jason Day [who made seven birdies in eight holes at the US PGA Championship on Friday], but that was a really good stretch."
