Kim then got another huge putt to drop at the 15th which got her within one of the long-time leader, but Jutanugarn regained her composure to knock a precise tee shot in close at the short 16th which lifted her spirits heading to the final two holes.
Jutanugarn confessed the memory of the ANA loss was coming back to her after she blew that tee shot into the woods on Sunday.
After misplacing his form on that infamous occasion then losing an 18-hole playoff to Billy Casper the following day, Palmer didn't like talking about what happened. Whether you agree with Azinger or not (and many on the Internet do not), Jutanugarn added some personal context during a Q&A this Monday morning. "It was odd, the front nine".
Jutanugarn was at 6 under overall after four holes when play was halted. Jutanugarn had some wiggle room. Still, there was candid reflection of events from the 10th after which she was "scared" to hit tee shots.
Duane Smith is the only caddie Sarah Jane has known and he has been at her side every step of the way, on and off the course, since she turned pro in 2004.
"He's like, 'Come on".
"Yeah. So my went back to my old clubs I have been using for a couple of years, I guess", said Smith.
"I don't feel comfortable", said Oh, who has also never won a major championship.
She has had a particular liking for Shoal Creek's back nine, playing it in 10-under. But Kim made bogey - her first of the day - on 18 while Jutanugarn made par again to send the format to sudden death.
Kim had been on the verge of becoming the eighth Korean victor of the event in the past 11 years.
Both parred the third playoff hole and they returned to the par-four 18th, where Ariya's superb bunker shot left her with a tap in for the win. Kim faced a hard, lengthy shot from the sand across the expanse of the green, and did a more than reasonable job with her attempt, but the door was ajar for Jutanugarn, who produced a spectacular up-and-down to win the Championship and complete one of the most tumultuous winning finishes in recent memory.
"She rolls the ball beautifully".
Even the smiles by design weren't really working.
"I felt really good and kept my nerves under control, but I think the nerves showed up in my putting", Smith said.
This is the first time the USGA has gone to a two-hole aggregate playoff, and Kim quickly took command by rolling in a long birdie putt on the 14th hole.
Sixty feet from the flagstick with a pond looming not far beyond, she blasted a fearless shot that trickled within a foot of the cup.
One thing they saw that was different this time: Jutanugarn didn't panic. "I am so proud of you".
That put her in a two-hole playoff with Hyo-Joo Kim, who shot 5-under 67.
There were lots of smiles after the long, wet week concluded with a long, wacky day.
Smith, a 33-year-old from Australia, had a three-shot lead going into the weekend after back-to-back 67s, but finished the tournament with two straight disappointing rounds. Jutanugarn's sister, Moriya, is also a professional player.
Smith played with a confidence that belied her recent poor results and a career resume that does not include a single LPGA victory in 222 starts.
"We got to this par-three and it played way downhill", he said.
