The 24-year-old recovered from a training incident, which saw him break his snowboard, to take victory with a total of 94.00 points.

Japan's Yūto Totsuka clinched the silver medal on 90.00 points, while bronze went to American Danny Davis, who scored 83.66.

James, who earned bronze in the halfpipe event at last year's Winter Olympic Games in Pyeongchang, last claimed the Winter X Games superpipe crown in 2017.

The Australian also won bronze in the same competition in 2018.

"I had a pretty horrible practice, which was really messing with me a little bit," James told the Aspen Times.

"I broke my snowboard and I hadn't done all my tricks yet or finished the run that I wanted to do.

"I was able to get up and get one more run in, but it was a new board, so it was a little bit hard for me to figure it out. 

"It was a pretty dramatic setup into the competition but I was stoked I was able to pull it off."

Alex Hall of the United States triumphed in the men's ski slopestyle final after his routine yielded a total of 95.66 points.

Canada's Alex Beaulieu-Marchand's first run score of 92.66 was enough for silver and Norway's Ferdinand Dahl picked up bronze on 80.33 points.
