The 31-year-old, who topped the halfpipe podium at the Turin 2006 and Vancouver 2010 Games, scored 100 points for the second time in his career to triumph by a margin of 3.75 points over nearest challenger Scotty James of Australia.

"Getting to the bottom and getting that perfect score was just nuts," White, who will make his fourth Olympic appearance at Pyeongchang 2018, said.

"I'm really proud of myself, it was a long way to get here.

"Now it feels like I'm on the right path to the Olympics.

"It's great.

"It's been all about making the Olympic team and having had a poor finish at the Dew Tour put a lot of pressure on me for the win at this event.

"And that was my goal, to win this thing."

Finishing behind two-time world champion James in the American resort was Japan's Yuto Totsuka, who was 5.50 points off the pace.

The US' Jake Pates and Ben Ferguson finished fourth and fifth respectively to secure Pyeongchang 2018 berths.

Pates managed 94.00 points, while Ferguson registered 85.25.

In the women's event, Spain's Queralt Castellet came out on top with 91.50 points.

The 28-year-old was the only European in the finals, which saw the US' Chloe Kim finish second on 88.75 points and compatriot Maddie Mastro come third on 87.25.

Castellet's victory was her first in a World Cup since she triumphed at the halfpipe event in Swiss village Saas-Fee in November 2011.
