Bad weather led to the cancellation of the halfpipe finals at the International Ski and Snowboard Federation Snowboard World Cup event in the Swiss resort of Laax, with Japan's Mitsuki Ono and Ruka Hirano claiming victories by virtue of their qualification performances.

Fog, snow and wind prompted organisers to cancel the finals altogether, having delayed the start by two hours on the Laax Open Superpipe course.

Slopestyle finals were postponed until tomorrow.

That meant Thursday's (January 19) qualification results stood as the final results of the competition.

Ono won her first Snowboard World Cup, scoring a winning 89.50 points on her second run after an initial 80.00 effort.

China’s Wu Shaotong in second also earned her first World Cup podium with 89.00 on her first run, and the United States' Maddie Mastro ended a wait of almost three years for a top-three finish by notching 82.50.

Ono holds an overall halfpipe lead after two events with 160, the winner of the first at Copper Mountain Queralt Castellet of Spain dropping to second on 150 after ranking fourth in Laax.

Hirano's qualifying score of 95.25 on his second run earned him a third career World Cup victory.

The winner of the season opener in Copper Mountain Scotty James of Australia, an Olympic silver medallist, was second with 95.00.

He was followed by world champion Yūto Totsuka of Japan in third with 91.50.

James leads the overall standings with 180 points, followed by Switzerland's Olympic bronze medallist Jan Scherrer with 116, after he ranked seventh at his home event, and Hirano with 114.
