ROCHESTER, N.Y. ? Rachel Teske shot an even-par 72 Saturday and extended her lead to four strokes after three rounds of the Rochester LPGA.

“I was kind of surprised — I thought somebody would be making a move but the conditions were pretty tough,” the 31-year-old Australian said. “I guess any time you shoot even-par and are still leading, it’s a good day.”

Teske, looking for her second straight win, opened with two sub-70 rounds and was at 7-under 209 after a round that was played in a drizzle early at the tree-lined Locust Hill course.

Stephanie Louden, Brandie Burton and South Korea’s Se Ri Pak and Soo-Yun Kang were tied for second at 213. Meg Mallon, the 2000 champion, was in a four-way tie at 214.

Pak, a two-time winner on the LPGA Tour this year, struggled on the greens and shot a 72.

“I’m hitting a lot of fairways; I was great on the tee and now I just have a problem on the green,” Pak said. “My ball never found the cup, I don’t know why.”

Teske, who beat Annika Sorenstam in a playoff last week, made a 20-foot birdie putt at No. 4, but gave that stroke back when she missed the fairway at No. 6 and two-putted for a bogey.

She saved par on No. 13, chipping to 5 feet from deep rough behind the green. She made a 15-foot par putt on the last hole after failing to get on the green with her approach shot because of a “shocking lie.”

“I hit the ball pretty well,” Teske said. But “a couple of times there was mud on the ball and I kind of hit some funky shots.”

Teske won the Giant Eagle LPGA Classic last Sunday.
