China's Ruoning Yin has shot a four-under 67 to take a two-stroke lead into the final round of the LPGA Tour's LA Open. The 20-year-old Yin had four birdies in a four-hole stretch on the back nine at Palos Verdes Golf Club and closed with two pars for a 14-under 199 total. "After eight, which I made a bogey with a three-putt, I just told myself and I told my caddie, I said, 'We just got to trust the line and putt it. We'll make some putts,'" Yin said. She had opened with rounds of 68 and 64 in her bid to win her first LPGA Tour title. "That means a lot, and not just for me, but also China Golf," Yin said about winning. "I think, yeah, it's going to be a big day." South Korean star Hyo Joo Kim was second after a 69. "Hopefully, the shots tomorrow will be better than today's," said Kim. Georgia Hall was third at 10 under after a tournament-record and career-best 62. The English woman is coming off a playoff loss last Sunday to Celine Boutier in Arizona. "I've been playing well pretty much all year," Hall said. "It really gave me a lot of confidence last week, although I lost in the playoff, I hit some really good shots. Just really pleased with the way I'm playing and just trying to keep it going." Hall played the front nine in seven-under 29 with two eagles and three birdies and added two birdies on the back nine. "I was just trying to stay really patient and I knew that I could take advantage of the front nine," Hall said. "I managed to get a couple eagles in there, which I was very happy about." Hannah Green was the leading Australian, tied 23rd after a 72 and 11 shots behind Yin, with Sarah Kemp (72) a further shot back while rookie Grace Kim was one over after a 72 and Steph Kyriacou (73) was four over.
