HT: South Africa 19-0 Wales
Wales won't rattle us, we are winning this. We need to win in order to learn from our mistakes. Simple.
Qhamani, Cape Town
Damage limitation is not overused when it comes to Wales playing some teams. We are so way off the standard required and the chopping and changing by Tandy isn't helping. We have good players left out and failures constantly brought back.

South Africa have gone back to what they are strongest at.
It was the perfect start for them, they put Wales under pressure straight away and Wales haven't got the answers so far.
Their biggest asset is their set-piece and they have had that taken away from them.

Here are the official Nations Championship stats at the break.
HT: South Africa 19-0 Wales
Image source, Getty ImagesThe final round of the summer fixtures in the Nations Championship got under way with a cracker in Auckland.
New Zealand and Ireland put their 100% records on the line and the All Blacks won comprehensively.
That was followed by France easing to a 42-15 win against Japan in Tokyo then Australia demolished Italy 57-10 in Perth.
Fiji played another ‘away’ game in Great Britain and after losing to Wales in Wales and England in England, they improved dramatically against Scotland in Scotland.
The Flying Fijians led on the hour at Murrayfield before the Scots pulled away to win 33-17.
After this fixture, the sixth and final Test takes place in Santiago del Estero and it is a fascinating game between Argentina and England (20:10 BST).
Will the result follow the football or can under-pressure Steve Borthwick cause something of an upset?
HT: South Africa 19-0 Wales
South Africa are very strong but their execution of play is quite poor at times which is holding them back from a much bigger scoreline Wales could potentially keep a few tries back in the second half for a less embarrassing defeat
Freddie, Scotland
Watched New Zealand play NFL against Ireland this morning, watching SA doing the same against Wales now. I think the northern hemisphere need to catch up

Former Wales fly-half on BBC Radio Wales
The word relentless has been used a lot during that first half and that's what South Africa are.
Despite their handling errors, all the territory and all the possession has gone in their favour.
Wales have barely had two half attacking chances. They have been lateral and not managed to get over the gain line and South Africa have been hunting at the breakdown.

For much of the second quarter, Wales had managed to frustrate the world champions.
The early roar from the home support had faded as Welsh resistance slowed South Africa's momentum.
At one stage, the travelling supporters even made themselves heard, with chants of "Wales, Wales" ringing around one corner of the stadium.
But the try on the stroke of half-time has quickly changed the mood.
The green and gold army are back on their feet, celebrating a 19-0 lead that perhaps better reflects South Africa's dominance, while the small pocket of Welsh supporters have been silenced once again.

They key word from that phase of play there is penalty, it allows you the confidence and the freedom to attempt that kick.
That's been the story of the first half, giving South Africa opportunity after opportunity from penalties.
South Africa 19-0 Wales
The kick is wide but South Africa have a commanding 19-0 lead at the break.
After the Boks won 73-0 in Cardiff in the autumn, it's a third half on the bounce that Wales have failed to score a point.
Jesse Kriel
A third try after the hooter sounds.
The Boks hammer away with big carries and penalty advantage.
Novice fly-half Vusi Moyo then goes for the lottery of a cross-kick and Jaco Williams puts the pressure on Tomos Williams.
The ball goes loose and centre Kriel picks up and dots down on the right.

An awful period of play, with a fly hack by Blair Murray and an attempted one by Dillon Lewis, ends with a penalty against Wales.
Lewis is pinged again for offside and South Africa will go for the corner with a minute of the half left.
South Africa 14-0 Wales
South Africa completely dominant and only their lack of execution is stopping them from racking up the points.
Simon, Malaga
SA do not need to really be at their best, or have a really full strength side... it is only Wales.

South Africa 14-0 Wales
A first glimpse of Wales in attack but it ends, like a lot of South Africa's efforts, with a knock on.
Nice line from Ben Thomas to get into the 22 but Rhys Carre fails to claim the pass from Tomos Williams, with Jasper Wiese in his eyeline.
South Africa 14-0 Wales
A nice kick by Blair Murray to put South Africa in their 22 for the first time in a long while.
Can Wales put pressure on the line-out with the greasy ball?
No, because they opt not to compete. South Africa clear to around 30 metres out.

With a team of such quality like South Africa, they are not going to take their feet off the gas.
But fair play to Wales, they've got up in the line and they are competing.
South Africa 14-0 Wales
Some fruity language from the visitors after their delight at another South Africa attack being ended by a knock on.
Nine visits to the Welsh 22 but just two tries for the world champions.
South Africa 14-0 Wales
Pieter-Steph du Toit thought he was over but ref Andrew Brace spotted obstruction.
He goes back to a penalty to the Boks and they go for the corner... not the best kick but they are 10 metres out.
South Africa 14-0 Wales
The humidity claims another victim.
This time it's a handling error from Ellis Mee and it presents South Africa with a scrum just outside the 22.
Great spot to launch a play, or just try to hammer the other pack.
South Africa 14-0 Wales
James Hook
Former Wales fly-half on BBC Radio Wales
The reason Wales are in touching distance is because of the errors from South Africa.
They've mad a load of handling errors, but it goes to show just how much possession they've had.
South Africa 14-0 Wales
Another 'red zone' failure by the Springboks.
The drive is pretty good but Malcolm Marx peels off and then knocks on.
South Africa haven't been at their clinical best but are bossing territory.
