A superb performance from the United States' Julia Marino saw her lead the qualification stages in the slopestyle competition at the Snowboard World Cup leg in Mammoth Mountain.

The Beijing 2022 silver medallist Marino was in sensational form at the Californian resort as she set the highest scores in both runs in the women's event.

Her second score of 78.59 saw her take pole position and seal her spot into Friday's (February 3) final.

Japan's Reira Iwabuchi overcame a poor first attempt to post 77.14 points and seal second place.

Annika Morgan of Germany fared similarly as her 75.14 was enough for third.

American Hailey Langland, Mari Fukada of Japan, Norway's Hanne Eilertsen, and Melissa Peperkamp of The Netherlands took the following four places on the leaderboard.

Fukada's compatriot Yura Murase then secured the eighth and final qualification place with a first run total of 65.28.

Belgium's Evy Poppy was the unfortunate ninth-place finisher, meaning she did not make the cut.

She cannot feel too hard done by though as a best score of 60.31 left her way off the mark.

New Zealand's Lyon Farrell topped the standings in the first men's heat with a score of 80.30 to narrowly beat Justus Henkes of the US by 0.10.

Japanese rider Taiga Hasegawa then rounded out the top three on 79.68.

In the second heat double Winter X Games gold medallist Dusty Henricksen of the United States posted the top score of any qualifier, managing 88.68 to finish top of the pile.

Australia's Valentino Guseli qualified in second with 81.50 with Chris Corning of the United States third in 81.33.
