South Africa 19-3 Namibia
Namibia win a penalty from the restart and it's kicked to touch.
Now it's their turn to influence the game from a line-out.
Cliven Loubser
That will do nicely.
Young fly-half Cliven Loubser dissects the posts with supreme accuracy and Namibia are up and running.
South Africa 19-0 Namibia
Namibia centre PJ Walters has just taken his place in the scrum so we can have contested set-plays, and the blue shirts are off.
JC Greyling bursts through a gap and that results the loudest cheer of the day.
Namibia recycle the ball and they win a penalty deep inside the Springbok half.
Can they get themselves on the board?
Mbongeni Mbonambi (con Elton Jantjies)
The South African line-out coach has earned his money today!
It's a third try from a rolling maul and Mbongeni Mbonambi has two of them.
The hooker will be eyeing a hat-trick, and this time, Elton Jantjies makes no mistake from the tee.
South Africa 12-0 Namibia
As if it wasn't hard enough already for Namibia.
Adriaan Booysen is sent to the bin for a deliberate knock on as South Africa look poised to run in a third try.
Francois Louw
It's a second try from another rolling maul after an efficient Springbok line-out.
This time it's Francois Louw who gets over the line at the back of a cluster of white shirts.
But it's only the five points as Elton Jantjies hits the upright with his conversion attempt.
South Africa 7-0 Namibia
South Africa are on the front foot straight from the restart and Makazole Mapimpi hares after his own chip through.
Cliven Loubser is on hand to mop up the loose ball but his kick clear remains in field and here come the white shirts again.
Mbongeni Mbonambi (con Elton Jantjies)
It's been coming!
Mbongeni Mbonambi throws the ball in from the line-out before joining the maul which powers over the line.
It's all too easy for the Springboks and Elton Jantjies accurately wraps his left foot around the ball to add the conversion.
South Africa 0-0 Namibia
Wallop!
Herschel Jantjies picks up and tries to snipe through a gap but he is hauled down just short.
The Springboks move the ball left and Elton Jantjies is hammered by Tjiuee Uanivi.
But the Namibian lock is offside and Jantjies prods the ball into touch.
South Africa 0-0 Namibia
The Springboks are flexing their muscles and they are dominating the scrum!
Namibia have lost two in the opening six minutes and now South Africa will have the put-in, just five metres out.
Here comes the shove!
South Africa 0-0 Namibia
South Africa drive through the Namibian scrum and Schalk Brits picks up the ball.
The powerful number eight rides a couple of tackles, but the try is chalked off by the TMO as he drops the ball before grounding it.
It's a let-off, but we will do it all again with another Namibia scrum.
South Africa 0-0 Namibia
South Africa have numbers wide but choose to tuck it up the jersey and drive through in the forwards.
They lose the ball forward and it's a Namibian scrum in front of their posts.
That is a chance spurned.
South Africa 0-0 Namibia
Full-back Warrick Gelant straightens his line and drifts straight through a gap.
The Springboks are just metres out and the early signs are ominous for Namibia.
South Africa 0-0 Namibia
Namibia clear their lines and South Africa will have the first line-out, just on the Namibian 22.
It's an ideal early attacking opportunity for the Boks.
South Africa 0-0 Namibia

We've had a cracking Saturday of World Cup rugby so far - and it's only 10:38 BST.
Japan are making a habit of springing the biggest surprises on the world stage and the Cherry Blossoms were at it again this morning!
The hosts followed up their 2015 heroics against the Springboks with a hugely entertaining victory over Ireland, who came into the tournament as the best team in the world.
The day began with a 25-minute hat-trick for hooker Julian Montoya as Argentina claimed their first victory of the tournament with a bonus-point win over Tonga in Pool C.
Over to you South Africa and Namibia...
South Africa v Namibia (10:45 BST)
Just to confuse matters for fans [and live text commentators] around the world, three of the half-backs in action today share the surname 'Jantjies' - but none of them are related!
So to help clear things up for you, this is Elliot who will pull the strings at fly-half for the Springboks...
This is Herschel, who plays at scrum-half for the Springboks...
And this is Namibia's Eugene, who will play opposite namesake Herschel...
Got it?
