GUADALAJARA, Mexico -- South Korea's In-Kyung Kim won the Lorena Ochoa Invitational on Sunday for her third LPGA Tour title, closing with an 8-under 64 for a three-stroke victory over Suzann Pettersen.
Kim played the front nine in 6-under 30 and added three birdies and a bogey on the final nine.
"I don't know how to really take this all in," Kim said. "But it's been a great week. I mean, on the golf course, I played very good golf all week. The putts pretty much kept dropping today.
"Yesterday, it was missing this way and that way, and today, it started going in, the next started going in, and another one, and I'm like, 'Wow.'"
She had a tournament-record 19-under total on the Guadalajara Country Club course and earned $220,000, which she said she's donating to charity -- half to the Lorena Ochoa Foundation and half to an American organization to be determined.
"Before I came to the U.S., I wanted to come to the U.S., but I know it's tough and my parents are working really hard at the time when I was 16," Kim said. "And we weren't really rich, but it takes a lot of money to send me to the U.S. and go to school and all that. But there is one person who helped my parents, and if he didn't help my parents, or if he didn't help me coming to the U.S., I wouldn't really be here. Everyone needs help. I think that's why I'm all about that."
Pettersen shot a 68. The Norwegian star has six second-place finishes and 11 top-five finishes in 18 starts this season. She's winless since the 2009 Canadian Women's Open.
"Another second-place finish. It sucks," she said.
Pettersen had a double bogey on the fourth hole.
"Hit one bad shot and that cost me two shots," she said. "And she made a birdie on the last. It kind of it felt like I gave her a gap. But other than that, I'm making some great putts coming down the stretch.
Karine Icher finished third at 15 under, holing out from the fairway on No, 18 for a 68.
Cristie Kerr (66) and U.S. Women's Open champion Paula Creamer (68) tied for fourth at 14 under, and Ai Miyazato (70) finished at 13 under.
Ochoa, playing her first LPGA Tour event since retiring in April, shot a 74 on her home course, leaving her 19 strokes back in a tie for 25th.
"For sure I wanted to play better, but I think it was important for the week for me to try to enjoy it as much as I could, and that's what I did," Ochoa said. "It was the first time to have my husband on the course, and I think we both had a good time. And I want to say `Thank you,' to the players for being here and making this tournament so special."
Husband Andres Conesa, the CEO of Aeromexico, caddied for Ochoa.
"It was a great experience, something that you don't change," he said. "Obviously, she would like to have a better round today, but she leaves very happy and it was a great experience for both of us."
Kim praised Ochoa after the victory.
"She's just down to earth," Kim said. "She is always there. She is not just a great golfer. She has great warm heart. So that's why she's my idol. I don't have many idols. I want you to know that."
Kim also won the 2008 Longs Drugs Challenge and 2009 LPGA State Farm Classic.
The tour is off the next two weeks. The season-ending LPGA Tour Championship is Dec. 2-5 at Grand Cypress in Orlando, Fla.
