PITTSFORD -- Leading money winner Yani Tseng fired a 6-under 66 on Thursday to take a one-stroke lead over Paula Creamer in the first round of the LPGA Championship at Locust Hill Country Club.
Meena Lee and Angela Stanford were 4 under, and Morgan Pressel, Stacy Lewis, Ryann O'Toole, Amy Hung and Hee Young Park were at 3 under.
Defending champion Cristie Kerr, who was ailing with a light case of the flu, shot an even-par 72.
Play was halted in the early evening by a severe thunderstorm with 58 players still on the course.
Tsengin the world, made five birdies on the front nine and three more on the back to go with a pair of bogeys. She recovered from a bad tee shot at the par-4 18th hole that landed in the thick right rough, hit her second shot to 4 feet, and drained the birdie putt for sole possession of the lead.
Tseng won the LPGA State Farm Classic on June 12 for her second victory of the year.
