SYLVANIA, Ohio – Alena Sharp and Youngin Chun shared the Marathon Classic lead at 7-under 64 on Thursday, a stroke ahead of Stacy Lewis and three others at Highland Meadows Golf Club.
The 38-year-old Sharp, winless on the LPGA Tour, had eight birdies and a bogey.
"I played really well right from the first tee shot," Sharp said. "I felt really calm this morning coming into this event. I always love playing here. I have great housing."
The 19-year-old Chun, also seeking her first LPGA Tour victory, had a bogey-free round.
"I didn't know I shot 64 today," Chun said.
