A score of 89.60 points gave Gasser the lead at the halfway stage ahead of Blouin who sat second with 82.40.

Blouin piled on the pressure with a second-run score of 90.20 only for Gasser to respond with a stunning tally of 95.40 to take the title.

Kokomo Murase’s third place finish with 87.20 was enough to clinch the Crystal Globe in the discipline.

Sven Thorgren of Sweden led the way in the men’s slopestyle event in Silvaplana after scoring 86.20 points in the first run.
