GUADALAJARA, Mexico -- Cristie Kerr fired a course-record, eight-under 64 Thursday to take a three-stroke lead after the first round of the Lorena Ochoa Invitational.

The old course record of 65 at Guadalajara Country Club was first set by Brittany Lang in 2008, then matched last year by Song-Hee Kim and In-Kyung Kim. The two Kims are not related.

Stacy Lewis posted a five-under 67 and is alone in second place.

Na Yeon Choi, the fourth-ranked player in the world, carded a four-under 68. She was joined in third place by Katherine Hull, world No. 10 Paula Creamer and world No. 6 Ai Miyazato, who was No. 1 earlier this year.

Current No. 1 Jiyai Shin is taking the week off, while No. 2 Yani Tseng struggled to a four-over 76.

Defending champion Michelle Wie withdrew after the first round due to a back injury. She had struggled to a six-over 78 on Thursday.

"I was very excited to be here, but unfortunately I can't play anymore," Wie explained. "We took an MRI and I have two little cysts near my spine and a little disc bulge. It's nothing major, but it's just something I can't play with right now."

Ochoa, the tournament host, came out of retirement for the first time since playing in the Tres Marias Championship in May. She opened with a two-over 74 that included three birdies, a bogey and two double-bogeys.

"It's good to be back," admitted Ochoa. "It would be better if I had a better round today."

Kerr carded three birdies in the first seven holes before catching fire. She birdied the ninth to make the turn at minus-four.

At the par-five 10th, Kerr made it two in a row. After Choi bogeyed the 13th to fall to minus-five, Kerr took the lead with a birdie at No. 11. She parred the 12th, then kicked off another run of three consecutive birdies on No. 13.

Kerr dropped her tee shot within nine feet at 13 and drained the birdie effort. She followed with a three-foot birdie putt on 14, then drained another eight-footer on the 15th to move to nine-under.

After a par on 16, Kerr three-putted for bogey at the 17th. She missed a birdie opportunity at the last, but still finish three clear of the field.

"I felt really good out there. I was there every shot," Kerr stated. "I want to do the small things well and take it day by day. I won today for myself, and I'll go out there tomorrow with the same amount of confidence."

Lewis had two birdies on the front nine and three more around the turn.

"I've been playing well, and I played really well today," Lewis said. "I even left a couple out there, which is good for the rest of the week. So I'm really happy with it."

Hee Young Park and In-Kyung Kim share seventh place at three-under 69

NOTES: Ochoa's husband, Andres Conesa, will serve as her caddie all week...Lewis has gone 61 straight holes without a bogey...Shin will remain No. 1 in the world regardless of who wins this week.
