White previously nabbed gold in halfpipe at Turin 2006 as well as Vancouver 2010.
All eyes will be on the top three in the final, while White had some words of advice for Japanese shredder Hirano, who won last month's Winter X Games.
The win gave the 31-year-old his third career gold medal at the Winter Games.
Team USA entered the PyeongChang Olympics with 96 gold medals in winter competition. "And whatever I do, whatever I say, the result can not be changed".
Fellow American teammate, Ben Ferguson, arguably one of the most creative riders in the halfpipe circuit, let loose an absolutely massive air-to-fakie on his first hit and followed it up with a glimpse of the doubles he surely plans to unleash in finals.
"Absolutely. I expected to Shaun to come out and put a run down like that".
"I was so overwhelmed with happiness, Ive been through so much to get here".
White immediately left the stage following the conference while reporters continued to question him.
But back on the Olympic trail, he also had to overcome the physical and mental scars of serious injury. Last fall he underwent emergency surgery on his nose and upper lip in New Zealand after smashing into the deck of the halfpipe during training and arrived in South Korea with stitches in his mouth that still hadn't fully dissolved. White says he's been working on the same combo and plans to do it here.
"I expected a battle and that's exactly what it was", James said. "It's wonderful. He's legendary". That flawless score came with comments by his competitors, including James who criticized the judges for awarding it. Jenkins is in second place going into Tuesday's gold medal round.
Earlier in the day, cemented his legacy as America's greatest snowboarder Wednesday by winning his third gold medal for the halfpipe in dramatic fashion. The 19-year-old Pates from Eagle and his teammate Chase Josey shouldered a load of nerves by stumbling on their first runs, forcing them to dig deep on the second and final run of qualifying.
Since then, Team USA has won at least one gold medal at every single Winter games and only Norway has won more Winter Olympic gold medals than the United States.
Asked if he felt he deserved gold instead of White, Hirano's answer was polite but firm.
The snowboarder has previously admitted to sending lewd text messages to Lena Zawaideh, and the parties later reached an undisclosed settlement.
"I looked down the mountain and said to myself, "you know you've got this, it's what you've done your whole life, stay with the moment and you will win the Olympics".
