Kelly Sildaru came into the slopestyle competition just one day after finishing second to Eileen Gu (CHN) in the halfpipe on Saturday. On Sunday however, she was able to flip the script, putting down an exceptional first run score of 93.75 that no one would be able to better through the rest of the day.

Through the top rail sections Kelly Sildaru started with a left foot front swap to pretzel 270 out on the first down rail, into a switch right foot front swap on the flat-down, and then a right slide to front 630 out of the Mammoth canon rail, before stomping perfectly her switch left 1080 mute and her switch right 900 tail grab on the jumps.

“I’m really so stoked,” Kelly Sildaru said just after the final results were in, “My baggage got lost on my way here and I haven’t done any training, only the warmups before the qualifications and the finals. So I’m happy that I was able to put a good run down.”

The win was Kelly Sildaru’s second of the season after she took the top spot at the slopestyle World Cup season-opener in Stubai back in November, and she remains atop the slopestyle standings with a perfect 200 points.

Behind Kelly Sildaru in second was Eileen Gu, making Sunday’s competition her first World Cup of 2021/22  that she hasn’t won.

Eileen Gu’s first run saw her go 270 on to 270 out on the first rail, switch left 270 Disaster on the flat-down, to left foot front swap to switch on the rainbow rain, and then a switch left bio 900 tail to right 900 Buick on the jumps for a score of 91.00.

While Eileen Gu would try to up the difficulty in her second run, she went down on her final hit dub 1260 and would not improve her score. Still, with her sixth podium of the season, Eileen Gu is well out ahead in the FIS Freeski overall standings, with 580 points to Sildaru’s 369.

Maggie Voisin of the host U.S. team matched her result from Mammoth two years ago, earning a score of 90.00 and third place with a run that saw her start with a left 270 on to 270 out on the down rail, into a switch left 270 Disaster on the flat-down, and then a right foot slide to backside 270 out on the rainbow rail, and then right 900 tail, and finally a switch left 720 high safety to finish it off on the jumps.
