SYLVANIA (AP) - Sei Young Kim shot a 5-under 66 on Saturday in the Marathon Classic to take a one-stroke lead over Lexi Thompson into the final round.
Kim had seven birdies and two bogeys to reach 16-under 197 at Highland Meadows Golf Club. The South Korean player won the LPGA MEDIHEAL Championship in May in California for her eighth tour title.
Thompson eagled the par-5 18th for a 65. She won the ShopRite LPGA Classic last month in New Jersey for her 11th tour title.
U.S. Women's Open champion Jeongeun Lee6 was third at 12 under after a 69.
Stacy Lewis (69), Jennifer Kupcho (69) and Carlota Ciganda (68) were 11 under.
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.
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.
