Australia's Sarah Kemp seized a share of the lead at 11-under 131 after the second round of the $1.4-million LPGA Jamie Farr Owens Corning Classic.

Kemp shot an eight-under 63 on Friday and shares the lead with American Laura Diaz who had a 67.

American Morgan Pressel is in third place after a three-under 68. She shared the first round lead with South Korea's Kim Song-hee and Diaz.

Kim, of Sydney, shot a 71 on Friday and is one of nine South Koreans in the top 20 but four strokes adrift of Kemp.

Lee Seon-hwa (63) is tied for fourth with countrywomen Shin Jiyai (67).

Michelle Wie remains in the hunt after shooting a two-under 69. She shares seventh at minus-eight, while Mexican world number one Lorena Ochoa (68) is tied for 13th at seven-under-par 135.

Kemp started on the back nine and birdied the 10th, gave that stroke back with a bogey on the 12th then rebounded with a six-foot birdie putt on the 14th. Another birdie on 18 allowed her to make the turn at minus-five.

Kemp rolled in four consecutive birdies starting at the fifth hole to move to 11-under.

"I just tried to stay in the moment. I knew I was playing good," Kemp admitted. "My putter was amazing. I don't know how many putts I had, but I don't think it was many. I just tried to have fun, and tried not to think about how many birdies I was making."

Diaz, whose last win was the 2002 Corning Classic, birdied four of the last six holes.

"I didn't make any birdies on my front side, but I just tried to stay patient out there," said Diaz. "I haven't been in place to be looking at the scoreboard in the last several months, so I really just was trying to stay in my own world."
