Sarah Hoefflin of Switzerland's chances of securing the overall International Ski Federation (FIS) Freestyle Skiing Slopestyle World Cup title were dealt a severe blow as she failed to qualify for the final on home snow in Silvaplana.

Due to weather forecasts predicting significant snowfall, organisers decided to also hold men's qualification today.

Finals for both men and women will now take place tomorrow instead of Saturday (March 4).

Hoefflin, the current overall leader, could only manage sixth place in the first heat and her performance leaves the door open for Norway's Johanne Killi to snatch the crystal globe.

Hoefflin has 259 points, 19 more than the Norwegian, who qualified by winning heat two.

Maggie Voisin of the United States won the opening heat with a score of 86.00 points, with Britain's Isabel Atkin earning second spot on 81.00.

Third place went to Giulia Tanno of Switzerland on 79.66, with Coline Ballet Baz of France's score of 77.00 proving enough for her to squeeze through to the final.

Killi produced the best score of the day as she reigned supreme in the second heat with 88.00 points and she will now go into the final as the favourite for the overall title.

Devin Logan of the US matched compatriot Voisin's 86.00 points to take second, while Emma Dahlstrom of Sweden was third on 79.33 points.

Mathilde Gremaud of Switzerland took the eighth and last berth in the final as she was fourth on 76.33.

A total of 16 skiers booked their place in the men's final during today's qualification round.

Switzerland's Andri Ragettli, who sits in top spot on the leaderboard, was among the qualifiers as he bids to defend his overall title.

Jesper Tjader of Sweden, who is currently third in the race for the crystal globe and has accumulated 116 points,  joined Ragettli and Woods in the final.

Ragettli, Alex Bellemare of Canada, Nick Goepper of the United States and New Zealand's Jossi Wells qualified from heat one.

American duo Gus Kenworthy and Bobby Brown sealed their berths in heat two, along with Christian Nummedal of Norway and Frenchman Antoine Adelisse.

McRae Williams of the US and the Canadian trio of Evan McEachran, Teal Harle and Matthew Wilcox were the qualifiers from heat three.

Tjader and compatriot Henrik Harlaut, together with Colin Wili of Switzerland and Canada's Noah Morrison, finished in the top four in the fourth heat.
