GUADALAJARA (Mexico) (AFP) Norways Suzann Pettersen shook off two late bogeys and made a clutch par putt at 18 to grab a one-stroke lead after Saturdays third round of the LPGA Lorena Ochoa Invitational. Pettersen, who began the day one stroke off the lead, fired a three-under par 69 to complete 54 holes on 12-under par 204 in the 1.1 million-dollar event at Guadalajara Country Club. Sharing second on 205 were South Korean In-Kyung Kim, Japans Ai Miyazato, Frances Karine Icher and American Stacy Lewis. All but Lewis fired 68s in Saturdays windy weather, Lewis finishing in 69. Its a roller coaster out there, Pettersen said. I hit some great putts, great shots. I know (my game) is there. I just have to play with it and find it. Pettersen began her round with back-to-back birdies, added another at the par-3 sixth and had another back-to-back birdie run on par-5 holes to close the front nine and open the back nine. But she struggled down the stretch, taking bogeys at the par-4 15th and par-3 17th and then finding a bunker on her approach to the green at the par-5 18th. Pettersen blasted out to five feet and sank the par putt to keep her lead with 18 holes remaining. Just a few poor swings, Pettersen said. I made the putt at the last. Maybe thats the key to tomorrow. Thank God there is another day tomorrow. Pettersen has 10 top-five finishes this year but has not won an LPGA title this season. She has five runner-up showings but hopes this will be her fifth title in 10 career events where she has led entering the final round. Miyazato, among five women who could claim Player of the Year honors after next months season-ending LPGA Championship, put herself in the hunt with a solid performance. Im playing really good so far but today was a tough day, Miyazato said. The wind was turning around. But I had good focus. I need to be just having fun with my game, just be natural and let it happen, just enjoy myself. US Womens Open champion Paula Creamer, the 2009 runner-up who led by a stroke over Pettersen when the day began, missed a five-foot birdie putt at 18 to stand on 206, one stroke ahead of Australian Karrie Webb, South Korean Amy Yang and Spains Azahara Munoz.
