(CNN) -- World No.1 Yani Tseng and Sweden's Karin Sjodin will go into the final round of the first women's major of the season tied for the lead at Mission Hills in California.
Sjodin fired a four-under 68 to join Tseng on nine-under 207 Saturday at the top of the Kraft Nabisco Championship leaderboard.
The contrast between the two players could not be greater, with Sjodin seeking a first victory in seven years on the LPGA tour, while Tseng is bidding to become the youngest player in history to win six golf majors.
The 23-year-old from Taiwan admitted after her round of 71 that she had become distracted.
"For the front nine, I played very solid, especially in this wind," she said.
"I don't think it was as tough as I thought, so maybe I was prepared for this. But on the back nine, I got kind of emotional, maybe thinking too much, trying too hard to play better."
Sjodin, reportedly playing with a dislocated rib, is enjoying her unexpected challenge.
"I never felt like I was ever in trouble. ... It feels great to be there. I don't know if I've really had time to think about it much. It's going to be fun tomorrow, definitely," she told the official LPGA Tour website.
South Korea's Haeji Kang was two shots back in third after struggling to a 72.
World number two Na Yeon Choi of South Korea was in a five-strong group on five-under.
Tseng, who has won three of five LPGA events this season, is hoping her third round struggles will be to her eventual advantage.
"'I'm glad this happened today instead of tomorrow,"
"I was just thinking too much and trying too hard. It's good to find out earlier."
Meanwhile on the PGA Tour, former British Open champion Louis Oosthuizen of South Africa led after three rounds of the Houston Open.
He shot his second straight six-under 66 to total 17-under 199, two clear of American Hunter Mahan.
Swede Carl Pettersson (67) and England's Brian Davis (69) shared third at 14 under.
Defending champion Phil Mickelson was six shots back alongside PGA champion Keegan Bradley and Ryan Palmer.
"It's a great leaderboard behind me," Oosthuizen told the official PGA Tour website.
"It's going to be tough, but I feel like I'm ready for it."
