Park Sung-hyun won the KPMG Women's PGA Championship on Sunday, defeating Ryu So-yeon in a tense playoff at Kemper Lakes Golf Club in IL.
However, the birthday girl, So Yeon Ryu, who turned 28, finished strong with birdies on 14, 15 and 17 to move into a share of the lead at 6-under par, along with first round leader Sung Hyun Park and 2016 KPMG Women's PGA Champion Brooke Henderson.
Fifth-ranked Ryu and sixth-ranked Park each birdied the first playoff hole, the par-4 18th, while Nataoka was eliminated with a par.
Park secured her second major since her victory in the U.S. Women's Open in July 2017.
"I did feel nerves going [into the playoff], but on the other hand, I haven't won a major yet, so I felt like I had nothing to lose", Hataoka said.
The announcement Saturday marks the second time in as many years that the PGA of America scheduled majors for men and women at the same course.
The 24-year-old said she drew upon her experience of winning last year's U.S. Women's Open and added, "Late in the round today, I kept thinking about what I did to win the U.S. Women's Open last year".
Ryu started the day in the lead and stumbled out of the gate with a double bogey on the second hole, dropping her score to nine under par.More news: Luis Suarez dedicates Russian Federation win to Uruguay fans
She finished third at the Meijer LPGA two weeks ago and tied for ninth last week in the Walmart NW Arkansas Championship.
As well as she played, Ryu also got an assist at the par-five seventh, where her second shot landed in a woman's food container, probably preventing the ball from going into a water hazard.
The par-4 16th hole proved to be the promised land for Park, who pulled off an incredible up-and-down for par in regulation and then clinched the title there in the playoff.
When Park sank her victor after Ryu had missed, Ryu, who had been in position to win her third major, was left to ponder the one that got away. "And I was really happy, like, I couldn't help that".
"I think this performance is one of my best performances I've ever had in my professional career", Park said. Her round included eight birdies and two bogeys as she vaulted 81 spots up the leaderboard.
"This year's (major) win means a lot to me since it made me go one step forward. She also had to battle herself to win this one".
"I don't want it to slip away my opportunity", Ryu said.
Park just missed a birdie on that hole when her 20-footer hit the edge of the cup. Hataoka missed hers, and Park, the last to putt, had to make hers to extend the playoff.
