Wales 21-15 South Africa
The South Africa pack are steamrollering their way through the Wales pack.
For the third time today, the Springboks have a penalty after Wales are sent backpedalling fast at the set-piece.
Handre Pollard punts up to the Wales 22m...
Wales 21-15 South Africa
Rhys Patchell has made an enterprising start, but that kick, going against the grain, is a little too clever for its own good.
Warrick Gelant reads it like a book, dropping back to claim it and then walloping the kick back upfield to take play to halfway.
Wales 21-15 South Africa
All aboard the showboat!
Rhys Patchell slings a pass behind his back and it very nearly finds Steff Evans for a stroll in.
The referee had already blown though as Patchell was offside from Hadleigh Parkes' chip ahead.

Rhys Patchell has come on for Dan Biggar at 10. Biggar is struggling with a little injury we think...

It wasn't a subtle move but it's very effective. You can't say South Africa don't deserve this.
Handre Pollard
Six points the difference and game very much on.
South Africa have come out rabid for the second half, quicker to the breakdown, more accurate with the ball in hand.
Handre Pollard takes the ball flat and fast five metres out and crashes through Aled Davies' stretching tackle like a set of Wild West saloon bar doors.
His conversion attempt hits the upright and bounces...out.
Wales 21-10 South Africa
South Africa have a penalty five metres out.
Time to go for the pushover scrum?
Nope, to the corner and an attempt to fire up the driving maul...

The forwards will not be happy to see that type of mistake made so early in the half. It was such a poor kick.
Wales 21-10 South Africa
Wales' first scrum of the second half creaks, but Aled Davies gets the ball away before the tremors turn to full-blown quake.
Hadleigh Parkes on the crash ball. But then Davies midjudges his box-kick sending it out on the full.
Line-out back to just outside the Wales 22m and pressure on...

Amby: A disallowed try for SA that was obviously a try, but wrong question asked; and then an obviously offside 3rd try for Wales. Technology only as good as the people using it.

We are back up and running.

Eben Etzebeth - South Africa's talismanic second row - has not made it out for the second half.
Teboho Mohoje is on in his place.

Wales just need to keep up their intensity because this game is not done by any stretch of the imagination.

It's embarrassing because these guys are athletes and they are playing exactly the way Wales expected them to play.
Wales deserve their 11-point lead.
Wales 21-10 South Africa
The tale of the tape from the first half.
There is not a lot of difference in the stats, but on the field there is a country mile with Wales on the South African windpipe for pretty much the entirety of the first half.

Justin Fairweather: Maybe Georgia should replace South Africa in the rugby championship?
Steve Handicott: Genuinely reckon I could round up 15 people off my street that would give South Africa a decent game...

Again a curiously polite reception after an extraordinary half of rugby.
In truth South Africa are lucky to be within 11 points at the break and what a half for Hadleigh Parkes on debut.
Chaotic rugby from the Springboks, opportunism by Wales, four tries.
More of the same please.

I just think Wales have been completely dominant. Dan Biggar has been superb and he's complemented their play.
Wales 21-10 South Africa
The referee blows up for oranges as South Africa skipper Eben Etzebeth hobbles to the sheds with a grimace on his face and a tweaked muscle in his leg.
