The 24-year-old is proving nigh on unstoppable this year, with her win in Southampton, New York coming after triumphs in the Kraft Nabisco Championship and the LPGA Championship, and she remains on course to complete a grand slam.
Park joins Babe Zaharias, who won three consecutive majors 63 years ago, in the history books but was quick to play down the hype.
"I just hope this is not a dream. I don't want to wake up tomorrow and play the final round again," she told the LPGA official website.
"I've just done three majors in a row now. I think it's too early to think about the next one. I think I really want to enjoy the moment as it is in the moment.
"I mean, the Grand Slam is very big. I probably wouldn't get this kind of opportunity ever again. I know this year is a good opportunity for me.
"But I think one of my goals for my career was the career Grand Slam, not the (single-year) Grand Slam, but I think a career Grand Slam is good enough for me and I haven't done that yet."
Park was earmarked for greatness when she became the youngest winner of this competition back in 2008 and her success at the Sebonack Golf Club was her fourth major win.
"It feels great to put my name on this trophy twice. That just means so much in this kind of great championship, I just feel very honoured to put my name on this trophy with some people who are up here. It's just great," she said.
The South Korean was far from her best although a two-over-par final round was enough to maintain a four-shot advantage over runner-up and compatriot In-Kyung Kim, who also carded 74 to finish on four over par overall.
Park bogeyed four holes with just two birdies and added: "The golf course was playing tough out there. I tried to stay calm and I think I did."
So Yeon Ryu made it an all South Korean top three, with her level-par fourth round seeing her finish on one under overall - two shots ahead of American duo Paula Creamer and Angela Stanford, and England's Jodi Ewart Shadoff.
