SYLVANIA, Ohio (AP) — Sei Young Kim shot a 7-under 64 on Friday to take a one-stroke lead over U.S. Women’s Open champion Jeongeun Lee6 in the Marathon Classic.
Kim had four straight birdies on Nos. 3-6 and also birdied the par-4 12th and 15th holes and the par-5 18th to get to 11-under 131 at Highland Meadows Golf Club. The South Korean player won the LPGA MEDIHEAL Championship in May in California for her eighth tour title.
Lee6 shot her second straight 66. The South Korean birdied two of the last three holes.
Lexi Thompson, Stacy Lewis and Jennifer Kupcho were 9 under. Kupcho shot 66, Thompson 67, and Lewis 68, with Lewis playing alongside Kim the first two days.
Lewis won the last of her 12 LPGA Tour titles in 2017. She was born in nearby Toledo and has an endorsement deal with Marathon Oil.
Thompson is coming off a two-week break.
Kupcho is making her sixth tour start as a pro. The former Wake Forest star won the inaugural Augusta National Women’s Amateur in April.
