In-Kyung Kim claimed a two-shot lead in the Women's British Open as first-round front-runner Michelle Wie fell away badly on day two at Kingsbarns.
Wie carded a women's course record of 64 on Thursday to lead Kim by a stroke, but the former slumped to a 76 in her second round and dropped out of the top 20 as a result.
At four under for the tournament, Wie was seven adrift of Kim, who shot 68 on Friday despite bogeying the first hole.
That error was immediately offset by a birdie on the second and Kim went on to pick up further shots at the ninth and 17th either side of an eagle at the par-five 11th.
Georgia Hall and world number two Lexi Thompson shot 67 and 68 respectively to share second on nine under, with Ally McDonald (68) one further back.
So Yeon Ryu, who tops the world rankings, and Lydia Ko each made the cut by a single stroke on one under.
