Jenny Shin birdied her 18th hole for the outright lead with a second-round 4-under 68 on Friday, nudging ahead of three golfers one stroke back in the LPGA Honda Thailand.
Shin sank the birdie putt to get to 11-under through 36 holes. In Friday's round, she used five birdies -- dancing around a bogey on the par-4 6th -- to hit the weekend atop the leaderboard.
One shot back are American Lizette Salas -- four birdies and a bogey-free 68 on Friday -- Australian Minjee Lee (69) and Eun-Hee Ji, the first-round leader from South Korea, who was one under in the second round.
Two-time Honda LPGA Thailand champion Amy Yang and Americans Austin Ernst and Amy Olson, a former North Dakota State player, are two shots back and 9 under for the tournament.
Olson's round was highlighted by an eagle on the 10th hole.
Yang tied for the low round Friday with a 66.
