Fantastic catch and mini break from Halfpenny – for a moment he thought he was away!
Wales 0-0 South Africa
Both sides already looking for the high ball.
Springboks number eight Duane Vermeulen collects from a Gareth Davies punt and grunts into several Welsh shirts, before Leigh Halfpenny snatches the return kick well.
The Springboks hold up the diminutive full-back and they'll get the put-in.
Wales 0-0 South Africa
Here. We. Go.
Handre Pollard gets the Springboks under way in Yokohama.

Gee whiz – this is going to be enormous!

The stomach is getting a little bit tight, knowing how much this means to both sides. I want Wales to win, they play a cracking brand of rugby and have some real totems, world class players. Alun Wyn Jones looks eerily calm – I like that!

Dave Sommerville: Can’t call this one - we are certainly capable of beating the springboks, we have done it enough times in recent years - but I also wouldn’t be surprised if they battered us
Wales v South Africa (09:00 GMT)
Wow.
Spine-tingling stuff from the Welsh, just look at the passion on Alun Wyn Jones' face during the anthem.

That is the dream, to get two home countries into the final would be sensational for UK sport, UK rugby and add the spice to the game that we have never seen before. This is bound to be a thrilling game in a different way.

Nervous yet? The atmosphere in Yokohama is incredible.
Before the anthems, those inside the stadium will observe a moment's silence to remember the victims of Typhoon Hagibis.

Jon Davies being fit is a huge bonus for Wales, he is one of the best centres in the northern hemisphere but we can see the amount of strapping on his leg – it’s very heavy, and I just wonder how fit he is?
Wales v South Africa (09:00 GMT)
Catherine Zeta-Jones, Carol Vorderman, Geraint Thomas and the Welsh First Minister are all getting rather excited about this one...
Wales v South Africa (09:00 GMT)
Wales scrum-half Gareth Davies will win his 50th cap and is due to lead out the side ahead of captain Alun Wyn Jones to mark the honour.
Davies has saved his best rugby for the 2015 and 2019 World Cups and has popped up for some very important tries.
Scarlets scrum-half Davies is master of the interception and Springboks will be wary of that threat today.

One interesting thing about the warm-up has been South Africa director of rugby Rassie Erasmus perched on the halfway line spending some time just watching the Wales forwards scrummaging and mauling.
Whether he can gain any late intelligence we are not sure but Erasmus has been an interested observer at least.
There was also a warm handshake with Warren Gatland before the game and Erasmus was very complimentary about the Wales coach in the pre-match build-up.

Radio Wales commentator Gareth Lewis talks to former Wales wing Adrian Hadley about how he thinks the World Cup semi-final against South Africa in Yokohama will go.
Hadley is confident of a Wales win with England awaiting the winners in the final next Saturday.

Gatland will have something up his sleeve - it might be a certain individual he is targeting. Remember, the team that have rattled England in the last year has been Wales. They might target the wingers, or leather the ball down the park, it could be short line-outs or quick tap penalties.

This is huge, it is absolutely everything. They have got to give everything, these boys have been with Gats for so long. It will be different to yesterday, but the intensity will be there.
Wales v South Africa (09:00 GMT)
This will be Wales' third semi-final and the second under head coach Warren Gatland, who will step down at the end of the tournament.
That will bring to an end a glittering 12-year tenure which has yielded four Six Nations titles - including three Grand Slams - and a first stint as the world's number one-ranked side.
This is also likely to be a final World Cup for some Wales players such as captain Alun Wyn Jones.
"I have got two games to go as the Wales coach and I want to enjoy these last two games, and there are probably nine or 10 players who won't be involved in another World Cup as well so they have got to relish that opportunity and be excited about this," he said.
"You have got a chance to do something special in your life and these chances come along very rarely and you have got to grab them with both hands."
