What has American Hunter Hess got left in the locker? Some big, big tricks but also a couple of errors.

A score of 58.75 puts him ninth.

And Xandra Velzeboer does it again! She is the fastest across the line and has a place in the semi-final with compatriot Suzanne Schulting and Italy's Elisa Confortola.

Just one more quarter-final to go.

The amplitude is good, but I don't think it's podium amplitude good for Birk Irving.

The top three from the first heat are about to do their second run.

You can watch along in the 'watch and listen' tab on this page and on BBC iPlayer.

Canada's Andrew Longino can't improve.

Birk Irving starts his final run just outside the medal spots - it's clean from the American but has he moved into the top three?

Not quite - 88.00 is his best score but he stays fourth.

Corinne Stoddard of the USA, Japan's Haruna Nagamori and France's Aurelie Leveque advance to the semi-final from the fourth quarter-final.

This fifth quarter-final is a great line-up.

Six-time Olympic medallist Suzanne Schulting of the Netherlands is making her first appearance of the Games, alongside compatriot Xandra Velzeboer who has won two gold medals in Milan so far.

Canada's Dylan Marineau puts his remaining chips on red and the ball lands in black.

His medal hopes over, he has a bit of fun with some extra tricks on the way down the halfpipe.

This is almost certainly Gus Kenworthy's last Olympic final.

Too heavy on the tail of the skis, but we salute Kenworthy for trying it.

He fought so hard.

The medal chances of GB's Gus Kenworthy are over.

It was looking a little scrappy throughout and he fights so hard but can't keep upright.

Benjamin Lynch's best result was 16th in the World Cup. Now, he has laid down this run.

Great run from the Irishman Ben Lynch! He looks delighted with that!

A score of 75.00 puts him seventh overall. A massive result.

Now here's Gus Kenworthy of Great Britain for his final run. He's fifth right now - will he improve?

Well that was a different quarter-final!

Belgium's Tineke den Dulk decided to ditch the rest of the group and sprint skate to overlap the rest of them and comfortably take the lead. A tactic I've not seen before.

She crossed the line the fastest with Olympic world champion Choi Min-jeong in second and Italy's Arianna Sighel in third.

Ben Harrington has pushed hard. He held that grab for so long.

An improvement to 73.75, which puts New Zealand's Harrington seventh.

It’s a party at the halfpipe. People are walking around with cardboard boxes full of beers.

Stood among the crowd at the bottom, it’s actually quite hard to move among the throngs of fans.

Like a nightclub on snow.

We have a VAR review in the second quarter-final. Just can't escape it can you?

Overtaking is allowed in short track speed skating but skaters must not obstruct or impede their competition.

China's Gong Li has been penalised for impediment after review and is out.

Canada's Courtney Sarault, Yang Jingru of China and Hungary's Maja Dora Somodi progress to the semi's.

Estonia have won a total of four gold medals at the Winter Olympics. All of them have come in cross-country skiing, the most recent in 2006.

Henry Sildaru could be about to make a bit of history for his country if he can hang on to top spot.

The third and final run is about to start...

There is a huge run waiting in there for Brendan Mackay, but he only has one chance to make it stick.

Brendan Mackay of Canada is last to go in run two. It's almost massive, but a slight squat on the landing off the last trick puts his final score in the fifties.

GB's Gus Kenworthy is fifth with one run to go and bang in medal contention if he can put it all together in the final run.

Henry Sildaru of Estonia leads.

It's about ticking those boxes for the judges. It needs to be bigger and cleaner from Nick Goepper.
