RANCHO MIRAGE, California, April 7, 2013 (AFP) - The 24-year-old Park, who also won the 2008 US Women's Open, blitzed the field on Sunday as she opened with two straight birdies in a round that also included a couple of 30-foot plus putts.
"I played so solid this week and this is a tournament that I always wanted to win," Park said.
Park finished with a 15-under-par 273 total to easily beat runner-up So Yeon Ryu, who closed with a seven-under 65 in the first major championship of the season.
Park, who also won the 2008 US Women's Open, earned her fourth tour title with a win in Thailand earlier this year.
On Sunday she and Ryu led a South Korean assault on the leaderboard at the Mission Hills Country Club as five of the top 12 finishers were from South Korea.
Park capped her win in the traditional fashion Sunday by leaping into the pond off the 18th green with her caddie. It is a move that has had health risks in the past but organizers have made it much safer to take the celebratory plunge.
"I was really worried about the first three holes, and the first three holes went really well today and that made my day much easier," said Park, whose previous best finish at this event was ninth five years ago. "I holed a lot of long putts today."
Sweden's Caroline Hedwall (68) and Norway's Suzann Pettersen (69) tied for third at nine-under, South Korea's Haeji Kang (68) and Aussie Karrie Webb (72) finished tied for fifth at six-under and South Koreans Jiyai Shin (71) and Hee Young Park (71) highlighted a group of six tied for seventh at minus-five.
Park took a three-shot lead over American Lizette Salas into the final round and quickly increased the margin with birdies on the par-four No. 1 and the par-five second hole.
Park never let up, collecting four more birdies in her brilliant round. Ryu said she never expected to catch Park.
"Inbee's putting is great so I didn't expect to win," said Ryu. "I just wanted a top-five and now I'm runner-up."
International players dominated the leaderboard as there were no Americans in the top 12. Paula Creamer and Jennifer Johnson were the top US players finishing in a tie for 13th with four others, including two Thai golfers Pornanong Phatlum and Moriya Jutanugarn.
Salas stumbled to a seven-over-par 79 to finish in a tie for 25th.
