Henricksen of the United States topped the season's slopestyle standings with a seventh-place finish in the Corvatsch 3303 resort, while Australia's Guseli took the overall park and pipe Crystal Globe.

Hasegawa, aged 17, won a Big Air World Cup in Kreischberg in January and earned his maiden victory in the slopestyle discipline with a fine performance on the Pro Line course.

Only three riders laid down clean runs on the first attempt, but Hasegawa delivered a stunning second to score 92.00.

That helped him to finish three points clear of Canada's Liam Brearley and seven clear of Sweden's Sven Thorgren.

"I’m so happy to get my first slopestyle podium and be first," Hasegawa said afterwards.

Henricksen finished seventh in the Swiss resort with 72.00, which ensured he finished top of the slopestyle standings on 296 points.

Hasegawa climbed into second place in the discipline on 186, with Guseli in third after failing to add to his 165 points with a qualification elimination.

However, it was still a memorable season for Guseli, who eased to the overall park and pipe Crystal Globe with 440 points.

The 17-year-old became the first rider in FIS Snowboard World Cup history to earn podium finishes in all three park and pipe events - Big Air, halfpipe and slopestyle - in the same season.

"I can’t really believe it yet," he said.

"I think there’s still more to push for and plenty more shredding to be had, but I’m super stoked to have this trophy in my hands.

"It’s definitely a goal I’ve checked off, but I’m already looking forward to next year and continuing to put on a show for all the beautiful people around the world and showing off what we do."

Henricksen finished second in the park and pipe standings with 332 points, followed by Hasegawa with 323.
