INCHEON, South Korea — In-Kyung Kim sank a 45-foot birdie putt on the final hole for a 3-under 69 Saturday, taking a one-shot lead after the second round of the LPGA Kolon Championship.

Kim shot a bogey-free round and totaled 5-under 139 heading into Sunday's finale of the 54-hold event.

She leads Hee-Won Han of South Korea (69) and Karen Stupples of England (70), who had four birdies in her opening 10 holes.

"With this wind, I didn't make any bogeys out there," Kim said. "The last birdie was something else."

Katherine Hull of Australia, who led by two shots after the opening round, struggled with a 76 and fell three strokes back. The Australian had an opening-round 66.

American Paula Creamer had a bogey-free round of 69 to trail by five shots. Defending champion Suzann Pettersen of Norway also shot a bogey-free 69, seven shots off the lead.
