ROGERS, Ark. (AP) So Yeon Ryu shot a course-record 10-under 61 on Saturday in the NW Arkansas Championship to take a five-stroke lead into the final round.
Ryu, the third-ranked South Korean star who won the ANA Inspiration in April for her second major title, reached 16 under to break the tournament 36-hole record by two strokes. She had her lowest score on the LPGA Tour and matched her professional best set in the 2012 Australian Ladies Masters.
Local favorite Stacy Lewis and Moriya Jutanugarn were tied for second. They each shot 65.
First-round leader Sung Hyun Park followed her opening 63 with a 73 to drop into a tie for 10th at 6 under.
Defending champion Lydia Ko was 5 under after a 67.
