Lydia Ko couldn't ask for a better venue on which to end her winless drought of nearly two years.
Lake Merced Golf Club, near San Francisco, has been the scene of two of Ko's 14 LPGA victories. On Saturday it was the scene of Ko's 5-under-par 67 that gave her a one-stroke lead going into the final round of the Mediheal Championship.
"I love San Francisco," said Ko, who was born in South Korea and grew up in New Zealand. "I'm a member here, and sometimes I get some friendly member bounces here."
At 11 under, Ko leads Jessica Korda by one shot.
