Frightened four times by a failed top nine, Chun admitted that the pressure of fighting for her first major in six years was taking its toll on her.
“I want to tell the truth, I couldn’t control all my pressure,” she told reporters.
“I think if I stick to my game plan, I’ll have a chance in the top nine, so I try to stay there.”
And she held on as Chun rallied with five pair and a deciding bird in 16th through the last six holes to end the day with three points and five fewer overall.
Champion of the US Women’s Open in 2015 and the Evian Championship a year later, this win marks the end of a four-year winless streak for Chun, whose most recent LPGA Tour victory came at the LPGA KEB Hana Bank Championship in October 2018.
In addition, she’s claiming $1.35 million from the PGA Women’s Championship record purse of $9 million, with prize money doubling from last year’s event.
“I’ve always said my depression is going away”
At an emotional press conference, Chun reflected on the culmination of a difficult four-year journey, during which she said some called for retirement.
“When I had a slump, some people said, ‘Ying-ee-ee, you should retire because your game is not very good right now,’” she said.
“But no matter what they say, I believe that I can win again. Now I’m so proud.”
In a conversation with her older sister last week, Chun admitted that, while struggling to “see the target”, she was thinking about leaving the US. However, when her sister encouraged her to quit golf in order to prioritize for herself, Chun realized she wasn’t ready to leave.
“I think this win feels really special because I’ve always said my depression was going away,” Chun said.
“I really cried [talking to her sister] … When I heard what she said, I believed that I still had the spirit, I still wanted to play golf.
“I am so happy that I won after everything that happened. I just want to keep saying, “I’m so proud of myself.”
“That’s why I want to continue to thank everyone who believed in me and never gave up on me.”
US Open champion Lee, who narrowly missed out on his second major tournament later that month, believes the victory will give Chan “a huge boost of confidence.”
“I think she went through a few hardships here and there,” Lee told reporters.
“So I think she will be very, very happy and just grateful to everyone around her.”
