World No 10 Sei Young Kim of South Korea carded a bogey-free 7-under-par 65 on Friday and took a one-shot lead after two rounds at the JM Eagle LA Championship in Tarzana, Calif.
Kim sits at 14-under 130 at El Caballero Country Club, just ahead of first-round leader Chizzy Iwai of Japan. Coming off a course-record-tying 63 on Thursday, Iwai carded a 68 on Friday, leaving her at 13 under.
South Korea's Ina Yoon holds third place at 12 under following a 64. Tied for fourth at 9 under are Melanie Green and South Korea's Jin Hee Im, who each shot 68 on Friday, and Jessica Porvasnik, who logged a 69.
Jenny Bae (second-round 68), Japan's Minami Katsu (69), Australia's Hannah Green (69) and Thailand's Suvichaya Vinijchaitham (71) are level at 8 under, tied for seventh.
Kim birdied two of the first three holes and was 2 under at the turn. She then reeled off five birdies in a seven-hole span on the back nine.
"Little less windy today, because yesterday (it was a) very dry golf condition because (I started in the) afternoon," Kim said. "So today ... I can attack to the pin more than yesterday."
Kim owns 13 career LPGA victories, but just one in the past six years, at the BMW Ladies Championship last October.
"This course (offers) a lot of the opportunity if you play well, so I think some players or couple players (will) play good and we'll see, yeah, what's going on," Kim said. "Yeah, (I) like my position so I just want to keep (moving) forward (the) next two days."
Iwai had another good round, albeit nowhere near as good as her first-round 63. She had two birdies and one bogey through the first 12 holes, then added three birdies in a four-hole stretch starting at No 13.
"My front nine, I didn't make ... short birdie putts, but my driver and my second shot was all consistent, my swing," Iwai said. "Yeah, my shot is pretty good."
Yoon charged into contention with a sizzling start to her round, making seven birdies and two pars on the back nine. She then played the front nine and cooled off, adding only one more birdie in a bogey-free day.
"First nine holes was awesome," Yoon said. "I never shoot 29 for nine hole in my life. It was unbelievable.
"The back nine was little bummer, but I had pretty good shot on the back nine as well. Some tricky putts on there. I made some. But it was good overall."
