SYLVANIA, Ohio (AP) Hyo Joo Kim had five birdies in a six-hole stretch and shot a 7-under 64 on Saturday at Highland Meadows to open a three-stroke lead in the Marathon Classic.
Kim began the run on the par-4 fifth, parred the par-3 sixth, then ran off four straight on the par-5 seventh, par-3 eighth and par-4 ninth and 10th holes. The South Korean player added birdies on the par-3 14th and par-5 17th and parred the par-5 18th to finish at 15 under.
Kim had shares of the lead the first two days, opening with a 66 on her 21st birthday and shooting a 68 on Friday. She won the season-opening event in the Bahamas for her third career title.
Top-ranked Lydia Ko and Alison Lee were tied for second. Ko, the 2014 winner, had a bogey-free 67. Lee shot 66.
