World No.1 Yani Tseng fired a two-under par 70 on Friday to grab a one-shot lead over five players, as the second round of the LPGA Founders Cup produced a log-jammed leaderboard.
Defending champion Karrie Webb carded a 69 and was among a group lying two shots off the pace on 137 that also included former world number one Jiyai Shin (71).
A day after she played one stretch of seven holes in seven-under, Tseng delivered a more sedate round of three birdies and one bogey on the Wildfire Golf Club course in Arizona.
After teeing off on 10 she parred her way through the back nine — the same stretch where she caught fire on Thursday — making her first birdie of the day at the par-four first.
After her only bogey of the day at the par-three sixth, the Taiwanese star birdied seven and eight.
South Korea’s world No.2 Na Yeon Choi carded a 69 to head the group on 136.
She was joined by South Korea’s I.K. Kim, who climbed up the leaderboard with a 66 and compatriot Meena Lee who carded a 67.
Japan’s Mika Miyazato posted a 67 and compatriot Ai Miyazato a 68 to complete the group sharing second.
Tseng, coming off a mammoth 2011 season that included 12 global titles — seven of them on the LPGA tour and two of them at major championships — last month successfully defended her LPGA title in Thailand.
