The Spanish Azahara Munoz takes one shot ahead on the last lap of the Ladies Scottish Open after title rival Stacy Lewis became frustrated with the "terribly slow" pace of play.
Munoz reached a third round 69 at the Renaissance Club in North Berwick to finish seven under par.
Lewis, who placed 70th , is the biggest challenger, with fellow countryman Jennifer Song two shots from the top.
The English Eleanor Givens is the best placed British player on one over.
Georgia Hall and Kylie Henry from Scotland are one step back.
Munoz, who had four birdies and two bogeys, said, "I love being out there. This break was really good for me. Just got back and want to golf play. ”
Former world number one Lewis, who played with Munoz and Song, had three birdies and two bogeys when she gave up her share of the lead.
"The biggest challenge for me tomorrow is to stick with what I'm doing, as the pace of the game is terribly slow, and that's not in my favor," said Lewis. "People I play with are pretty slow."
New Zealand's Lydia Ko forfeited a five-shot six-hole lead to play in last week's Marathon Classic, but returned immediately
She achieved a bogey-free 67, the lowest lap of the day, leaving the leader three times behind.
