A stroke ahead after an opening 64, Kim had an eagle, four birdies and a bogey to get to 12-under 130. The 23-year-old Australian patiently worked her way around the tree-lined layup, trying not to get frustrated with the bumpy greens.
“I think the less thoughts, the better,” Kim said. “Obviously, during the afternoon round today, we’ve got poa annua greens so just have to stay patient with them. You can kind of see how it can get bumpy, so working with the course and not getting too wrapped up around putts not going in.”
Maja Stark was second after a 69, also in the afternoon.
“I feel like maybe not taking everything so personal because they are a little bit wobbly,” Stark said. “Especially late. Like the whole day pretty much the ball has been wobbling because there has been so many people walking on it.”
The Swede finished second last week in Texas in the Chevron Championship, two strokes behind top-ranked Nelly Korda in the first major of the year. Korda withdrew Monday, a day after her fifth straight victory.
Defending champion Hannah Green of Australia shot a 69 to join Germany’s Esther Henseleit (68) at six under. Denmark’s Kristine Pedersen (67) and American Auston Kim (71) were five under, and Irvine’s Rose Zhang (69) topped the group at four under.
Grace Kim won the Lotte Championship last year in a playoff in Hawaii for her first LPGA Tour title. She missed the cut in the Chevron, shooting 76-72.
She started play Friday on the back nine, rebounding from a bogey on the par-three 12th with the eagle on the par-five 13th and a birdie on the par-four 14th. On 13, she hit a 5-wood to 10 feet. She added birdies on Nos. 3, 6 and 7 on the second nine.
“I think I’ve got to breathe a little bit,” she said. “I did get a little bit nervous on my back nine, so making sure I don’t rush too much and just staying in the present.
