Park is one of five South Koreans to win on the tour this year, and she is the first from the contingent to grab multiple titles in 2018.
In this EPA photo, Park Sung-hyun of South Korea cries after sinking the clinching putt on the second playoff hole to win the KPMG Women's PGA Championship at Kemper Lakes Golf Course in Kildeer, Illinois, on July 1, 2018.
The organization announced on Saturday that the 2023 KPMG Women's PGA Championship and 2029 PGA Championship will be played at Baltusrol Golf Club in Springfield, N.J. Both championships will be staged on Baltusrol's Lower Course, an A.W. Tillinghast design that opened in 1922.
The birdie-birdie finish made it five for Park on the day after a bogey-free round that included a remarkable par save at No. 16, where she chipped out of tall grass at the edge of the water to about 3 feet.
Park Sung-hyun raised her arms in jubilation and the tears began to fall. Ryu missed the green in her second shot, but made her birdie putt from the fringe.
Her 3-wood off the tee hit a bunker on the left side of the fairway and an 8-iron went to the water on the right.
Meanwhile, out on the course, Park flirted with disaster on the challenging par-4 16th hole. The shot was reminiscent of Pak Se-ri's barefoot shot at the U.S. Women's Open in 1998 (inset).
Nine strokes behind Ryu entering the day, the 19-year-old Hataoka almost pulled off one of the biggest comebacks in LPGA Tour history.
Hataoka, 19, won her first LPGA title last week in Arkansas and with more than US$546,000 in the past eight days has eclipsed her prior career earnings.
Canada's Brooke Henderson, who was second through three rounds, had a disappointing final day of 74, dropping her into a tie for sixth at 6-under 282.
"This win means a lot to me, since it made me go one step forward", Park said.
"Winning this tournament is going to be huge because I never really dreamed about becoming a Grand Slammer", she said.
Park carded a closing three-under-par 69, while overnight leader Ryu battled to a 73 in strong winds. Then, playing the par-5 11th - which is reachable in two - Henderson's birdie chip from off the green ran well past the hole, and now she needs a new wedge.
In regulation, Park was trailing Ryu by one stroke at 10-under, when she almost put her second shot into water short of the green.
Park almost took a one-shot lead at the 17th, but her long birdie attempt lipped out.
The back-to-back birdies by Ryu and two late bogeys by Henderson turned things in a hurry.

It was the latest in a series of arguments about football and the relative merits of the world's two best players. They both won very differently, but now two big contenders will go head-to-head.
