American Mo Martin had a plan to play Royal Birkdale. It has worked better than she imagined at the Ricoh Women's British Open.

Martin took two putts from short of the green on the par-5 18th for her 10th birdie in two days. It gave her another 3-under 69 and a three-shot lead over Beatriz Recari of Spain and former U.S. Women's Open champion So Yeon Ryu going into the weekend.

The weekend will not include Michelle Wie.

Coming off her first major in the U.S. Women's Open at Pinehurst No. 2, the 24-year-old from Hawaii never got anything going and fell apart over the closing stretch for a 78 to miss the cut by three shots.

Only nine players remained under par and wind has yet to get fierce.
