SYLVANIA, Ohio (AP) -- Sei Young Kim won the Marathon Classic on Sunday for her second LPGA Tour victory of the season, making five straight birdies in a mid-round burst and shooting a 6-under 66 for a two-stroke victory over Lexi Thompson.
Kim began the birdie run on No. 7 and finished at 22-under 262 at Highland Meadows Golf Club. The 26-year-old South Korean player has nine tour titles, also winning the LPGA MEDIHEAL Championship in May in California.
Thompson, a stroke behind Kim entering the day, closed birdie-eagle for a 66.
Six shots ahead of Thompson after the birdie run, Kim played the final seven holes in even par, offsetting a birdie on 15 with a bogey on 1.

U.S. Women's Open champion Jeongeun Lee6 had a 69 to finish fourth at 14 under.
