Ariya loves to binge watch Thai dramas, but she scripted her own in the final round of the 73rd U.S. Women's Open.
Speaking after her win, Jutanugarn said: "I'm really honoured to join the list of players before me. I didn't hit my tee shots very well, but it was a fun day".
Now she'll just try to stay on an even keel throughout the weekend.
Jutanugarn certainly looked like it on Saturday, combining long drives with a solid short game and putting. The advice proved paramount when May's clubs didn't arrive in time for a Monday practice round, and she began the championship having laid eyes on only nine holes of Shoal Creek. "But, I'm not nervous or excited anymore when I have playoff", she said.
Former World No.1 Ariya Jutanugarn, from Thailand, was in a share of second place with Oh at six under - through seven holes of her second round - when play was suspended for the day. She took the lead after Smith stumbled with back-to-back bogeys and then surged ahead with three consecutive birdies on the back nine. She is four shots behind Smith, who is at 10 under 134 for the tournament.
Smith started the tournament with back-to-back 67s, but didn't make a birdie in the third round. "I'm happy with the way I'm playingk", Smith said. "Not because I want them to play golf, but because I want them to have a good life".
South Korea's Kim Hyo-joo was alone in third after shooting a four-under 68 while another shot behind was Kim Ji-hyun (70) at five-under 211.
Sarah Jane had a four-stroke clubhouse lead over fellow Australian Su Oh with half the field yet to complete the round.
Of the other Australians in the field, last week's victor Minjee Lee is two over through six holes of her second round and is tied for 38 place.
The pair then needed four extra holes to be separated, with a par on the 18th hole enough for Jutanugarn to win the championship. Cameras caught Jutanugarn applauding the shot. "I go to tee off on 11 and I told my caddie, 'I don't know how to hit this one, '" Jutanugarn said.
Smith had the advantage of finishing her second round on Friday before thunderstorms swept through central Alabama, but couldn't capitalize.
The Thai, by contrast, made further bogeys on the 12th, 17th and 18th.
Jutanugarn confessed the memory of the ANA loss was coming back to her after she blew that tee shot into the woods on Sunday.
Kim was searching for her first LPGA win since January 2016 and her second career major after the 2014 Evian Championship.
Canadian Brooke Henderson, who shot 73 on Thursday, withdrew due from Friday's round due to personal reasons.
Two-time victor Inbee Park has an outside chance at getting back in contention.
And when she finally fought back from that, she endured yet another collapse, this one with a chance to win her first major.
"I feel great", Ariya said.
