LOS ANGLES (AP) — Grace Kim opened a four-stroke lead Friday in the LPGA Tour’s JM Eagle LA Championship, shooting a 5-under 66 in tricky afternoon conditions at Wilshire Country Club.

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.”
