Switzerland's Andri Ragettli has moved into first place with a score of 78.65.

The commentators were talking about the execution of his blender ... nope, I have no clue either.

Sweden's Anton Grahn and Italy's Simone Dapra take the final two semi-final places in the sprint classic.

Dapra's Italian compatriot Federico Pellegrino is one of the 'lucky losers' that will also progress, as will Finland's Lauri Vuorinen.

Norway's Oskar Opstad Vike and USA's James Clinton Schoonmaker were the two fastest skiers in quarter-final four and progress to the semi-final.

The fifth and final quarter-final is under way now ...

There's a lot of nerves in this final.

We've just seen world silver medallist Mac Forehand take a fall so his first run has only scored 1.25 points.

That is not the start the American will have wanted.

A South Korean coach is running around the outside of the rink, with some money in her hands, to lodge a protest with the officials.

She's absolutely legging it! Apparently you have to pay to submit a complaint.

OUCH! The United States team suddenly go down and they completely wipe out South Korea.

Belgium had been last all along there, but they take advantage of the chaos to move into Final A along with Canada.

Here comes the second semi-final, with Canada, South Korea, the US and Belgium all trying to make it through to Final A.

Games hosts Italy will be happy to see Simone Mocellini progress through to the semi-finals of the sprint classic.

He was the fastest performer in the third quarter-final, with 21-year-old Jiri Tuz crossing the line 0.08 seconds after.

A huge shock here, as the Netherlands will not progress to the final. No speed skating medal for the Dutch? Almost unheard of!

It was an unforced error from Xandra Velzeboer too, as she lost balance on a corner under minimal pressure. The look of anguish on her face told a story.

There are Dutch journalists with hands on heads all around me in the press box. This is a turn-up.

What drama?!

France crash out, and then the Netherlands do to, with Xandra Velzeboer slipping. The Dutch team were the hot favourites.

Italy cross the line first, with China also making it through to Final A.

USA's Ben Ogden was the fastest to the line in the second heat of the sprint classic quarter-final.

The 25-year-old, who is also a mechanical engineer, finished nearly two seconds quicker than Sweden's Alvar Myhlback in second-place.

USA's Mac Forehand and Alex Hall will be ones to watch, as will Norway's Birk Ruud in this freeski slopestyle final.

Each athlete will have three runs.

So the first semi-final will be contested between the Netherlands, Italy, China and France.

The first and second team in each semi-final qualify for final A, while the third and fourth teams qualify for final B.

Here we go...

GB's Niall Treacy, speaking to BBC Sport after crashing out of heat four in the 1000m short track: "Bit frustrating obviously, but I felt I was in a good position, I felt physically strong, holding my line and I heard an athlete come [alongside me] I didn't know who it was. I felt it was a little bit late and tight and I wanted to defend my position. It's the Olympic Games, you can't be pushed around.

"It's unfortunate that the referee called joint responsibility because it's not even like it was my fault, it was his fault so, frustrating but I'll dust myself off and come back for the 15s."

On going out to attack the race from the front: "That's how I've raced for the past four years - it suits me quite well and is one of my strength's to make the race quite hard. I like that secuirty of being in the fastest thirds if it doesn't go well but to have it end like that is frustrating. But like I said, this is short track and this is something that happens."

On processing what happened: "It's a bit difficult because in the moment, I'm defending my line and then afterwards it's a tight call and you don't know if you're in the wrong or if he's in the wrong so, it's like get up, finish the race and see what the referee has to say."

Before we get into the semi-finals of the speed skating mixed-relay, let's hear what Team GB's Niall Treacy had to say after crashing out of his race a short while ago...

So, how is this freeski slopestyle final going to work?

Well, the top 12 skiers will compete in reverse order of their qualification ranking for each of the three runs.

Only the best run will count towards a skiers final score, with the athletes judged out of 100 per run, based on amplitude, technical difficulty, creativity and landings.

The men's freeski slopestyle final is about to start.

These events are coming thick and fast today aren't they! My fingers are bashing the keyboard trying to keep up ...

Watching Johannes Hosflot Klaebo is a real joy. It's like the man doesn't even break a sweat?

The reigning Olympic champion went from being last to first in that race in about 150m.

His time of three minutes and 30.66 is slower than this morning's qualifying time but it doesn't matter as he is through to the semi-final.

So is his compatriot Erik Valnes.

Johannes Hosflot Klaebo, the golden man of cross-country skiing is back in action in the men's sprint classic quarter-finals.

Just two days after Sunday's X-Cross final where he won gold, the Norwegian is back in on his skis and on the hunt for another Olympic medal.

Can the reigning Olympic champion successfully defend his title?

He's going to take some beating with a record like this, isn't he?
