"Literally, 'just shut your mouth and attack, ' " said the 23-year-old, who had a 5-under 67 on Sunday at Trump National Golf Club Bedminster to overtake 54-hole leader Shanshan Feng of China and 17-year-old amateur Hye-Jin Choi of The Republic of Korea for her first victory in North America.
Feng will enter the final round of the tournament Sunday afternoon with a one stroke lead as she shot a 1-under 71 and had a one-stroke lead with a nine-under 207 over a tight field that has the top six golfers within four strokes of each other at Trump National Golf Course.
Park, who birdied the 15th to move into a tie for the lead and the 17th to open a two-shot edge after Choi made a double bogey on the previous hole, finished at 11-under 277 for a two-stroke win. The Chinese player's triple bogey on the last hole sent her tumbling from second to fifth place.
Sung Hyun Park overcame a three-shot deficit and the heartbreak of a near-win in last year's event to capture the 2017 U.S. Women's Open.
World number one Ryu So-yeon of South Korea (70) and compatriot Hur Mi-jung (68) shared third on seven-under.
President Donald Trump arrived at the course late Friday afternoon from his trip to France.
A scintillating Sunday shootout that showcased the seemingly bottomless pool of youthful talent in women's golf produced a victor who just might be the game's next big thing. She led after 36 holes in this event past year and finished third, two shots out of a playoff.
"She's young and long so she hits the ball very long and very straight, very accurate and has very good short game also", Feng said.
South Koreans have won six of the past nine US Women's Open crowns and have a shock contender in teen prodigy Choi, trying to become the first amateur to win the US Women's Open in half a century. She got to three under for the day after birdies on Nos.
"Earlier on the 18 hole, my mind basically went blank", Park said.
Feng, the oldest member in a three-way duel at 27 and by far the most successful with seven LPGA titles, a major championship at the 2012 KPMG Women's PGA and an Olympic bronze medal, simply did not make enough birdie putts. She was brilliant from tee to green but made 33 pars over the last 36 holes and only a pair of birdies. "And, you know, I'm not surprised that she won this week because I was just talking to my friends, I said, 'As good as she is, she's going to win anytime.' So, yeah, I'm happy about her, for her".
"But I think today my caddie (David Jones) had a great role in helping me stay focused".
"Coming to this week, I didn't have any expectation at all".
With three holes left in the US Women's Open, Hye-Jin Choi was all set to re-write the record books. "I don't see any weak part in her game". Park played the weekend in 67-67 after an opening-round 73.
