Quote MessageThe crowd is starting to sense what would be a famous victory. We've seen many tries scored in the last 10 minutes but you wonder if South Africa's confidence has been knocked. They are still going and Wales are tired."
Bread of Heaven ringing around the stadium. Warren Gatland watching on, arms crossed. Wales inside enemy territory, with put-in at the scrum. We're entering the final 10 minutes.
James Hook is introduced and so is Justin Tipuric. Tyler Morgan and Dan Lydiate the men leaving the field. 12 minutes or so remaining. Knee-knocking stuff. Wales have a line-out a smidgen inside South Africa's half.
South Africa sniffing around Wales' 22m, but for how long can Wales hold on. Incredibly, they steal possession, - Dan Lydiate magnificent - and kick downfield once more.
The men in red on the ropes, but they're rolling with the punches, asking the Springboks: "Is that all you've got?"
Every time South Africa attack, Wales seem to force a turnover and have nine to the Springboks four.
The Springboks are dominating possession but Wales' defense is holding firm.
They have made 132 tackles, over twice as many as the Boks.
For territory and possession there's only one team in this half, but South Africa lacking the guile to penetrate Wales' defence.
The Springboks lose possession, Gareth Davies kicks downfield... the ball bounces off Jamie Roberts' shin. JP Pietersen collects... and boots to touch.
An error-strewn high-octane encounter which can only be watched through the lattice of the fingers.
South Africa 18-19 Wales

Quote MessageYou want to bounce back straight away... great work by Wales. Dan Biggar is a match winner, everything is going his way."
South Africa 18-19 Wales
Wales' riposte is immediate and clinical. South Africa's forwards lackadasical. Wales counter-rucking with intent. Wayne Barnes adds spit to whistle.
Dan Biggar ruthless, immaculate, peerless. Three points. Wales in the lead once more.
South Africa 18-16 Wales
Bryan Habana charges down a Gareth Anscombe kick. Wales are penalised at the breakdown. Handre Pollard with another chance to put his side ahead and, after two misses, he curls it the right side of the posts.

The men in red have forgotten what it feels like to be on the front foot, which is perhaps why they mess up, with Alex Cuthbert kicking possession away.
JP Pietersen kicks towards George North... volume increases inside the stadium as the behemoth wing gathers speed but runs into a green wall...
Wales' rush defence firing on all cylinders. Dan Biggar getting man and ball to stop the flow of green shirts crashing towards his team-mates.
Duane Vermeulen going high on Jamie Roberts and Wales will be relieved that Dan Biggar can boot them into opposition territory for the first time since the second half kicked off.
As good as South Africa's back row has been in attack, Wales' back rowers are more than matching them in defence.
Dan Lydiate has made a game-high 17 tackles, captain Sam Warburton has 12 tackles and four turnovers while number eight Taulupe Faletau has 12 tackles to add to his 10 carries.
Scott Baldwin is on the floor, seeing stars and birds circling around his head after coming off worse in a tackle with Eben Etzebeth.
The hooker needs to leave on a mobile stretcher and is replaced by Ken Owens.
Former England hooker Brian Moore thinks Dan Biggar is the best number 10 in the world. Do you agree?
Wales off the hook. For now. But the Springboks have enjoyed 75% possession in this half and, perhaps inevitably, gaps begin to open in Wales' defence.
A shuffle of the hips from Willie Le Roux and the full-back is sashaying towards the line. Brilliant. Bryan Habana waiting on the wing for the pass, but Wales' defence hold firm. Incredible from both sides.
South Africa 15-16 Wales
