What it means: Kim is looking for her first LPGA win since 2005.
Round of the day: Kim and Shanshan Feng tied for the day's low round, 68. Kim had five birdies and a bogey, and Feng was bogey free.
Best of the rest: So Yeon Ryu was one of four players to shoot 3-under 69. Like Feng, she was without a bogey, making birdies at Nos. 2, 12 and 13.
Biggest disappointment: A day after leading the field with a 65, Paula Creamer came in 11 strokes higher, at 76. She had two bogeys and a double, failing to make a birdie.
Main storyline heading into Sunday: In addition to the race to win this tournament, there are several important subplots as the LPGA season heads for its finale at the season-ending CME Group Tour Championship next week in Naples, Fla. At stake are the Rolex Player of the Year Award, the Race to the CME Globe and the official money title. The competition for Player of the Year and the money title comes down to Stacy Lewis and Inbee Park, but the Race to the CME Globe is more wide open, with a points reset setting up a battle for the season-long competition’s $1 million prize. Only the top nine in points will go to the Tour Championship with a chance to win the jackpot.
