SPRINGFIELD (AFP) - South Korea's Mindy Kim fired a career-low 64 on Thursday to grab a two-shot lead after the first round of the LPGA State Farm Classic. South Korean Jiyai Shin and Australian Sarah Kemp were tied for second on 66, while Brittany Lincicome -- the winner last week at the ShopRite Classice -- birdied her final hole for a 67 that put her tied for fourth with Taiwan's Yani Tseng and Juli Inkster. Kim's round included five birdies in a row from the second hole. After a bogey at the ninth, she birdied four more holes coming in -- 11, 12, 14 and 17. Kim, who has three top-10 finishes this year, has the lead at an LPGA event for the first time, and she admitted she was nervous. "I did not expect this at all," she said. "I hit the ball great today. I hit everything close. I think that's what made (the round)." Her lone bogey was a piece of bad luck, with her tee shot plugging in the soft ground in an unplayable lie. Kemp's round included seven birdies and a bogey, her birdies tending to come in pairs. She opened with two straight birdies at the first and second, but gave a shot back with a bogey at the fourth before a birdie at the par-five sixth. Coming in she made back-to-back birdies at 12 and 13, and at 15 and 16 thanks to a hot putter.
