(Reuters) - South Korea's Kim Sei-young dropped two shots on her last three holes and was replaced at the top of the leaderboard by compatriot Ji Eun-hee in the third round of the JTBC Founders Cup on Saturday.
Ji shot a bogey-free 65 to move to 18-under-par at the Wildfire Golf Club in Phoenix, Arizona, one shot ahead of 2015 rookie of the year Kim (70) and American Stacy Lewis, who carded a 64.
World number one Lydia Ko and Spaniard Carlota Ciganda also shot 64 to move into contention at 15 under.
Kim drained a 25-foot eagle putt from the front fringe of the par-4 13 to move two shots clear but failed to pick up a birdie at the straightforward par-5 15th and then made bogeys at 16 and 17 to close with a two-under-par 70.
