A year to the day (AEDT) since James led the Australian Team into the PyeongChang Winter Olympics Opening Ceremony, the VIS Athlete blew away his competition to claim an unprecedented third straight title, becoming the only male in history to secure the feat in halfpipe.
During his first run, the PyeongChang 2018 bronze medallist scored a whopping 94.25, which remained unobtainable for his competitors throughout the finals, but not for James, with the triple Olympian going one better and putting down a jaw-dropping 97.50 in run three.
Japan's Yuto Totsuka claimed silver with a score of 92.25 and Patrick Burgener from Switzerland took the bronze at 91.25.
James commended the calibre of the competition and said winning his third World Championship crown was a surreal experience.
"I was pinching myself when I won my second world title, and I'm triple pinching myself now that I've won my third one, it's absolutely amazing," the 24-year-old said.
"The level of riding was incredible, I was on my toes, I knew those last two guys behind me had a lot in them to pull it together so I just wanted to land that run and do it the way I wanted to, so I'm over the moon," he finished.
Fellow Aussie and dual-Olympian Kent Callister finished in fifth place with a score of 79.00, which was a personal best finish at the World Championships for the NSWIS rider.
The win continues an incredible unbeaten season for James, which includes gold at the X Games and championships across Europe and North America.
James will continue his undefeated run into his next competition at the US Open event in Vail, CO, USA, on March 2nd.
Also in action for Australia at the World Championships was 2018 Olympian Emily Arthur, who finished in 18th place.
