Springbok skipper Siya Kolise was replaced at half-time.
He's stil making his way back from a serious knee injury that looked as though it would rule him out of the World Cup.
Amazing that he's back and he looked top drawer.
Marco van Staden on.
Wales 9-24 South Africa
Just a reminder, Rio Dyer has another three minutes in the sin bin.
I still think the penalty try was harsh - the bounce had eluded the wing.

Wales have conceded four tries in that first half against a rampant South Africa attack so home defence coach Mike Forshaw will not be happy.
It is a strong South Africa side against an experimental and inexperienced Wales side and that is showing starkly so far.

The damage to Wales is being done in the middle of the pitch where South Africa are breaking through tackles and Wales can't get them down.
I don't know how to stop them truth be told.

Inexperience has cost Wales in that first half, but you look at the half overall and I don't think South Africa have offered that much.
They're not four tries better than Wales.
Wales' scrum has been defective and they've made mistakes that have cost two tries, a fair score would've been South Africa with two tries.

Right then Wales fans... I'll throw a couple of names out and you can say with a thumbs up or down if you would take them to France.
Ready?

I spoke to quite a few South Africa fans on the way to the stadium earlier, they were all pretty confident that they would put 30 points on Wales today.
Their prediction is looking very likely right now.

South Africa are dominating in every area of the game now, especially in the scrums and with their big forwards.
Wales just can't get them to the ground. The Springboks are moving the ball cleverly and Wales also haven't dealt with the ball in the air.
So there are a lot of things going wrong for Wales, that was immature play by Mason Grady, I thought he was on the plane to France!
And they do - but only just as South Africa again threatening at the whistle.
This has been a testing 40 minutes.

Wales HAVE to hold out to half-time.
They've just seen a 12-9 deficit blow into 24-9 in seconds and are down to 14 men.
Big few minutes.
Wales 9-24 South Africa
Yeah Grady getting supportive pats on the back of the head from his team-mates.
He's a young man still finding his feet at this level and is facing one of the most experienced centre-pairings in world rugby.
I still see him going to the World Cup and he will learn from that.

It would have been a scrum five metres out for South Africa if Mason Grady had put the ball down.
He's tried to get his arms free to offload and as he's done that the ball has come out of Grady's hands.
The whole stadium is quiet now, it shouldn't have been a penalty try and now South Africa have capitalised on a Wales error.
Jesse Kriel
Oh no, South Africa immediately grab another but what was Mason Grady doing there? He just threw the ball in the air.
Damian de Allende kicks ahead, Grady did well to get back and gather but then suffered a rush of blood to the head.
He throws the ball up into the grateful hands of Kriel.
He's off for ten

Dyer denied a scoring chance and South Africa have the penalty try.
Wales 9-12 South Africa
That all started from another burst from Siya Kolisi. He looks soooo good.
Willie Le Roux follows with a neat little kick, the bounce evades Canan Moodie and Dyer hit the ball away with his left hand behind the try line.
The TMO is taking a long time.
