PHOENIX (AP) Mirim Lee remained atop the JTBC Founders Cup leaderboard in her third LPGA Tour start.
The 23-year-old South Korean player shot a 5-under 67 on Friday to take a two-stroke advantage over 16-year-old Lydia Ko into the weekend at Desert Ridge's Wildfire Golf Club.
A three-time winner on the Korean LPGA, Lee played the final eight holes in 5 under, making an eagle and three birdies to reach 13-under 131. She opened with a 64 on Thursday for a one-shot lead.
Ko, the Canadian Women's Open winner as an amateur the last two years, shot 66. The first-year pro played a late six-hole stretch in 6 under with an eagle and four birdies.
Sun Young Yoo was third at 10 under after a 65.
