Caroline Masson continued her charge at the top of the standings to open up a two-shot lead in the British Open.
The 22-year-old from Dusseldorf had never led an event before but was in fine form again during her round of 68.
She missed an eagle chance on the 17th but will begin Sunday's final round ahead of defending champion Yani Tseng.
Scotland's Catriona Matthew also carded a 68 to move onto nine under in third place but In-Bee Park's challenge was harmed by a one-over par round of 73.
"I did enjoy it," said Masson. "I mean, I was quite nervous at the beginning, I made bogey on the first hole but then birdied the second, so I felt really confident after that. I'm really excited for tomorrow and really looking forward to it.
"It's more like the mental side that you just accept whatever is coming, the conditions, that you're prepared for bad bounces or maybe an unlucky shot or whatever.
"Sometimes I'm getting mad when I get a bad bounce or whatever, so I think that helped me a bit to stay calm on the course."
Masson may hold the advantage but Tseng will be considered favourite to add to her haul of majors.
The 22-year-old Taiwanese won the title last year and hit an eagle on the 14th on her way to a 66 - the best round of the day.
"I played awesome," said Tseng. "I feel really good and I'm very excited about tomorrow."
And 2009 champion Matthew, who won the Scottish Amateur Championship over the famous links 20 years ago, feels the is still in with a chance.
"It helps that I know the course, but I think Yani and Caroline feel pretty happy here now too," said the 41-year-old.
"But I think it going to be windier tomorrow and that could suit me. It's also great to have the crowd on your side, especially when the putts are dropping for birdies."
