Ai Miyazato fired a 7-under-par 65 Saturday for a one-stroke lead heading into the final round of the Honda LPGA Thailand 2012 tournament. Miyazato, who won the event in 2010, had five birdies in a six-hole stretch of the second nine in moving to 14-under 202 after 54 holes. Yani Tseng last year\'s winner in Thailand, had a second consecutive 65 and is second at 13-under. Jayai Shin, who shot a third-round 68, and Karrie Webb, with a 71 Saturday, are tied for third at 12-under and Amy Yang is at 11-under for the tournament after a 4-under 68 Saturday. Webb owned a three-stroke lead after Saturday\'s completion of the weather-delayed second round and Miyazato still trailed by three after a 2-under front nine. She tied for the lead with back-to-back birdies at Nos. 10 and 11 and moved in front with three straight birdies over 13-15. Tseng was tied for the lead with Miyazato and Webb after nine holes Saturday but fell back to Miyazato\'s hot streak. She pulled close with a birdie at the 18th.
