Of the four men who have gone in run one so far, American Troy Podmilsak leads the way with a score of 90.50. Fellow countryman Konnor Ralph is just behind on 86.50.

Sweden's Martin Nordqvist had quite a heavy landing on his first attempt but thankfully was up on his feet quickly, while Canada's Dylan Deschamps looked to have snapped his right ski when he failed to stick his landing.

In the first two runs, the competitors go down in the order they qualified - with the top scorer going last.

Chance here for Team GB... right, Bruce Mouat, what have you got?

Ooft, that's what he's got, a double-takeout. But Brad Jacobs does just enough to make sure he gets his one to restore a two-shot lead going into the fourth end.

Do you get ultras in curling? Because I think the Italian ones are in tonight. And their favourites are responding by gesturing encouragement to them after good shots. It's magnificent theatre, if nothing else.

Encouraging to see that even curlers, who spend their lives on the ice, sometimes lose their footing.

Daniel Casper of the United States has just decked it a belter, but bounced back up and saluted the crowd.

American Mac Forehand - who won the X Games a few weeks ago - was the highest-scoring qualifier for tonight's final, just ahead of Austria's Matej Svancer.

Luca Harrington of New Zealand, a bronze medallist in the slopestyle, is the reigning big air world champion. He turns 22 on Friday so will be celebrating his birthday with another Olympic medal?

There's no British representation in the final - GB's Chris McCormick finished 21st during the qualification phase.

As the snow continues to fall in Livigno, one of the men we'll be keeping a close eye on in tonight's big air final is Norway's Birk Ruud.

He won slopestyle gold earlier in these Winter Olympics and is the defending champion in this event from Beijing four years ago.

He qualified third without the need for a third run.

Shout out to the cameramen up at the sliding who basically give themselves whiplash every time a sled goes by as they have to whip round from one way to the other to catch the sled flying past at speeds of around 70mph.

It’s taken me nearly two weeks to manage to get a snap of one actually just whizzing past.

So, when you've got the hammer - the right to throw last - the idea is to try to get multiple points in the end. The Canadians did that in the first, but GB couldn't in the second.

What can Canada do in the third?

A field of 12 have qualified for the men's freeski big air final, which we hope will be getting under way in the next few minutes after a weather-enforced delay.

Each competitor gets three runs down a large ramp to launch off and attempt to perform their best tricks while airborne.

Six judges score each attempt out of 100, with points awarded for difficulty, execution, amplitude and landing.

The highest and lowest judges' scores are discarded, with the four remaining scores averaged out to provide a final score for each jump.

A competitor's two best scores are combined to give them their overall score, but they cannot simply do the same trick three times - their two counting scores must come from two different tricks.

Expect big tricks and big drama...

I think this is the 15th consecutive day that I've been in this arena and I'm not sure I've heard it as loud as it is tonight.

Italy are playing the United States on the adjacent sheet and the explosion of noise when they took two in the second end was ear-splitting.

Horns, bells, cheers... all sorts.

Steve Cram
Curling commentator on BBC iPlayer

Much better from Team GB in this end. A really good shot from Grant Hardie.

Great Britain did not do a lot wrong but if the competition are capable of good shots, they can take it away.

Canada are on it tonight. A splendid double-takeout means the second end only yields one for Bruce Mouat's rink.

Quite the trousers that the Norwegian lads are wearing tonight...

As expected that was a slow push from Brad Hall and Leon Greenwood.

They sit ninth before the final heat.

They will aim to put everything into the four-man event later this week.

It's 45.54 points and fifth place after five skaters for Kristen Spours.

Only the top 24 (out of 29) advance to Thursday's free skate.

An early mistake from Team GB. Bruce Mouat will have been hoping to get off to a good start after a disappointing loss against Norway.

A perfect start for Canada - but if Team GB play their best they will win.

There will not be a knock to their confidence, the camp seem happy and up for it.

If that is the last time we see Kristen Spours on the ice, she can leave figure skating with her head held high.

Hers is a story of remarkable resilience. Back from spinal surgery to win the British national title. The break helped her rediscover her desire to skate.

Because of her back injury, Kristen Spours is unable to perform a double axel - one of the required elements of a short program.

It therefore goes down as an invalid element, always leaving her at a disadvantage compared to her opponents. It may cost her a place in the free skate.

But given all of the hurdles she has had to face, physical and mental, it is even more impressive than most that she has skated at the OIympics.
