Carlsbad, California: World No. 1 Yani Tseng, a winner in two of four starts this year, fired a four-under par 68 to seize a two-stroke lead after the second round of the $1.7 million LPGA Kia Classic.
Taiwan's Tseng, a favorite in next week's first major event of the year at Rancho Mirage, sank an 18-foot birdie putt on the 18th green to finish 36 holes on nine-under par 135, two strokes ahead of South Korean Se Ri Pak.
"I told myself (at the 18th tee) I just needed one good drive, one good shot and one good putt and I'm done for the day and that's what I did," Tseng said. "I just have to be patient, play my game. I should be all right this weekend."
