Park, who won the KPMG Women's PGA Championship by an impressive margin of five strokes last month, will be competing with nine previous champions for the title. Defending champion Michelle Wie, Na Yeon Choi (2012), Paula Creamer (2010), Laura Davies (1987), Eun-Hee Ji (2009), Cristie Kerr (2007), Birdie Kim (2005), So Yeon Ryu (2011) and Karrie Webb (2000, 2001) are all in the field for this year's event.
The South Korean welcomes the competition that such a strong field brings as she believes that she is at her best when playing in high pressure situations.
"That's the tournament that you put 100 percent of your energy and strategy and everything," Park, who won the U.S. Women's Open in 2008 and 2013, told reporters. "When I come to major championships, I work extra hard and I try to look at the course a little bit better.
"Having good results helps, that gives me a lot of confidence going into other major championships thinking that I've done good on major championships so I can do well in another good one."
The tricky Lancaster Country Club course features tough elevation changes, sloping greens and troublesome rough, but Park believes that she will be able to clear all these hurdles with no problems whatsoever.
"I am good at the tough golf courses," she said. "I am good under the pressure. I just try to keep talking to myself that way and try to give myself the confidence coming into the major championships."
Following her victory at the KPMG Women's PGA Championship, Park's good run of form ended when she missed her first cut of the year at the Walmart NW Arkansas Championship two weeks ago.
While Park was disappointed to have faltered after winning a major, she believes that it was a much-needed wake-up call.
"I putted really bad two weeks ago, and that definitely gave me somewhat like a wake-up call because I haven't really had a bad tournament or a really bad week," she said.
