ROGERS, Ark. (AP) Sung Hyun Park nearly matched the course record with an 8-under 63 on Friday to take the first-round lead in the NW Arkansas Championship.
The South Korean, ranked eighth in the world in her first full season on the LPGA Tour, finished with nine birdies and needed only 24 putts to take a two-shot lead over Mel Reid, Ally McDonald and So Yeon Ryu.
Reid had a hole-in-one on the par-3 11th and reached as low as 8 under before falling back with a pair of back-nine bogeys.
Local favorite Stacy Lewis was one of five players three shots off the lead at 68.
Defending champion and second-ranked Lydia Ko opened with a 70.
