That scrum was a huge, defining moment for Wales, but how angry are the South African pack going to be?

It's been so tight, but space is starting to open up out there.
Malcolm Marx carries into contact but Rhys Carre rips it from his grasp. Big turnover.

Madness came the cry as Wales captain Alun Wyn Jones opted for a scrum when this set-piece area had struggled against the Springboks all game.
His bravery pays off as Wales ensure quick ball with Tomas Williams and Jonathan Davies releasing Josh Adams for his sixth try of the tournament.
Leigh Halfpenny takes over the kicking duties and duly slots over the touchline conversion to level the scores again.

Game on.
What a finish we have coming up here...

What did we say - attack the space, attack wide - we attacked the space with pace and the players we've got and that was a massive kick as a conversion from Leigh Halfpenny.

England head coach Eddie Jones predicted yesterday that this game would go to extra time. Sure he’d be very happy if it did...

Big call, big moment! What a call from Alun Wyn Jones to go for the scrum! They had parity in the scrum, then it was a three v two in the left.
Josh Adams (con Leigh Halfpenny)
It's there!
Swift hands from Tomos Williams and Jonathan Davies puts Josh Adams in at the corner.
The Wales wing makes no mistake from there, Adams dives over to roars around the stadium in Yokohama.
And Leigh Halfpenny levels up with the extras - what a kick from the touchline!
Wales 9-16 South Africa

I don't know why they kept battering against that wall. I don't understand why we don't attack where the space is

Wrong option, putting it on the ground – stick it in the air, anything can happen.

Posts? No, Alun Wyn Jones says Wales will take the scrum five metres out...

That's 15 phases for Wales since the line-out, Tomos Williams is instructing his forwards into position. Dillon Lewis goes low but can't make a dent.
Wales get the penalty, and now look to grubber over the line for the wide men to attack... sliding across comes Faf de Klerk, like a Premier League goalkeeper.

Aaron Wainwright is repelled as the green wall holds firm, Wales are looking to be patient. Ken Owens crashes in, still the Springboks hold out.

Wales are up to within one metre of the Springbok line...

Dan Biggar is normally so solid in defence but the Wales fly-half was guilty of missing South Africa centre Damian de Allende on the outside as Springboks score the first try of the game.
Biggar went too high in the tackle and paid the price. It proves Biggar's last involvement in the game as he is replaced by Rhys Patchell.

Rhys Patchell, on for Wales in this second half, lashes a long penalty into touch to set the position for Wales. Adam Beard takes it well...

De Allende hands off one after another - he's got so much power. It's easy if Dan Biggar, but he doesn't and Tomos Williams can't handle the power of the big man.
