Gu's last event before the World Cup in Canada was the Beijing 2022 Winter Olympic Games, where she was the poster girl for the host nation - winning titles in ski halfpipe and big air as well as silver in slopestyle.

Symbolic of her dominance over the last 18 months, Gu again recorded the best three runs of the women's halfpipe final, meaning all six of the best scores over the two finals came from her.

Her best today was a second-run attempt that gave her 93.50, accompanied by scores of 90.00 and 91.75.

Canadian Rachael Karker, who took silver on Thursday (January 19), was again comfortably second with a best of 85.50 coming from the first run.

The gap to the rest of the field was shorter as Zhang Kexin broke the 80-point barrier with a first run of 81.75, but was unable to make it a Chinese one-two with a botched last attempt.

Americans Hanna Faulhaber and Svea Irving were fourth and fifth, followed by the Canadian duo of Dillan Glennie and Amy Fraser.

Kim Dae-un of South Korea was unable to get a decent run together, finishing eighth.

There was an American one-two in the men's halfpipe, with two-time Olympic medallist Alex Ferreira standing top of the podium.

He overtook compatriot and eventual silver medallist Birk Irving in the second round with a score of 94.50; while Irving could only respond with 93.00.

Remarkably, Noah Bowman of Canada took the bronze medal after two discarded runs had him bottom of the order - only to execute a final run of 90.50 to demote with team-mate Simon d'Artois down to fourth.

David Wise of the United States was fifth, unable to improve on his opening effort, while New Zealand's Finley Melville Ives was sixth - carrying the flag for the nation in the absence of Olympic champion Nico Porteous, who is recovering from an anterior cruciate ligament injury.

Jon Sallinen of Finland, who won the first leg, could only finish seventh, followed by last round's silver medallist Brendan Mackay of Canada.

Americans Cameron Brodrick and Tristan Feinberg completed the final field.
