ONEIDA, Wis. (AP) – Sung Hyun Park made nine birdies in an 11-hole stretch Friday on her way to a 10-under 62 and a one-shot lead over Monday qualifier Yealimi Noh in the Thornberry Creek LPGA Classic.
Park, coming off a victory in Arkansas that returned her to No. 1 in the world, was at 17-under 127.
Noh, who chose to turn pro instead of going to UCLA, has made one bogey in 36 holes and finished off her round with a 6-foot birdie putt on the par-5 ninth for a 65.
Ariya Jutanugarn had a 64 and was two shots behind.
Noh played in the last group with Presley Cornelius, the 20-year-old amateur and Oneida Tribal member playing on a sponsor exemption. After opening with a 96, Cornelius shot 105 in the second round.
