Hyo Joo Kim took the third-round lead Saturday in the LPGA Tour's JTBC Founders Cup, finishing another long day at Desert Ridge in Phoenix in the dark on the 18th green.
The 19-year-old South Korean player shot a six-under-par 66 to take a two-stroke lead over 2013 winner Stacy Lewis, who shot a 67.
Kim made three consecutive birdies -- the last with a 25-foot putt on the par-four 16th -- and closed with two pars to finish at 16-under 200. Kim holed her 1 1/2-foot par putt at 6:51 p.m. -- 11 minutes after sunset.
Alison Lee and second-round leader Kim Kaufman were third at 13 under. The 20-year-old Lee matched the course record with a 63, and Kaufman had a 70.
Top-ranked Lydia Ko was 12 under after a 69.
Marco Dawson made a 15-foot par putt on the par-four 18th for a five-under 67 and the second-round lead in the Champions Tour's Tucson Conquistadores Classic.
The 51-year-old Dawson, making his 21st start on the 50-and-over tour, opened with two birdies, made four in row on Nos. 7-10 and had his lone bogey on the par-three 17th.
Dawson had a 10-under 134 total in the first-year event on Tucson National's Catalina Course, the longtime home of the PGA Tour's defunct Tucson Open.
Wes Short Jr. and Bart Bryant were nine under. Short eagled the par-five second hole in a 66. Bryant, coming off a playoff loss to Lee Janzen last month in Naples, Florida, had an eagle on the par-five 10th in his 67.
