Wales prop Nicky Smith tells S4C's Clwb Rygbi at half-time: "You've just got to match them [Argentina] but that's easier said than done. They're big men.

"If we can sort the discipline out and the errors, keep the scoreboard ticking over, hopefully we can get the win."

After that first Wales try, it's all been Argentina.

There's been some sloppy errors from Wales that have been their own undoing.

That must have been a draining half for Wales, who were put under serious pressure by an impressive Argentina side.

All that tackling in this searing heat? Exhausting.

Wayne Pivac's young team are still in this game, though. This is invaluable experience for his fringe players.

Nicolas Sanchez tries his luck with a drop-goal effort from long range, around 40 metres out, but it drifts wide.

The clock is red. Last phase of the first half coming up.

Another testing defensive scrum for Wales inside their 22 and it holds firm enough to allow Jonathan Davies to boot clear.

That's an excellent kick from the captain, taking his side up to the halfway line.

Argentina's forwards have got a taste for it now, and number eight Rodrigo Bruni sets off on another bruising carry.

Bruni's having a stormer.

A couple of phases later, this time it's the Pumas' turn to be let down by their handling and a knock-on gives Wales a scrum inside their own 22.

That's the challenge for this young, inexperienced Wales team. Stay in the game and try wrestle control back.

A bit of respite for Wales, who kick a penalty into Argentina's 22. Great kick from Jarrod Evans.

But that's followed by a big groan from the crowd as the lineout goes awry, Argentina clear and Hallam Amos knocks on near Wales' 22.

A forgettable few moments for Wales.

Argentina are so powerful in the tight. They almost never fail to break the gain line.

Facundo Isa is the latest to burst his way through the Welsh defensive line, setting his team up to clear into Wales' half.

Just every time Argentina get into Wales' 22 it looks like a foregone conclusion. A tough afternoon so far.

Tom Rogers gets his hands on the ball on the left wing again but makes another error, rather throwing the ball away as he tries to offload.

Argentina counter-attack and go all the way from their own 22 to the Welsh 22.

Jarrod Evans is covering and fortunately for him, Matias Moroni, is deemed to have knocked on as he tries tackling.

Actually, it's a scrum to Argentina. Referee Luke Pearce says it was Evans who knocked on first.

Yet more pressure for Wales to withstand.

Fly-half Nicolas Sanchez slots over a simple penalty to extend Argentina's lead.

They are well on top at the moment.

Here comes the lates wave of Argentina pressure, with the Pumas swarming the Wales 22.

The Welsh defence is structured but tackling constantly in this heat is tiring.

Argentina have another penalty, this time in front of the posts.

The next scrum, inside Argentina's half, goes the other way with a penalty going to the Pumas, who pulverized Wales' pack there.

Big test for Wales' pack and they pass it, earning a penalty as referee Luke Pearce says Argentina's front row are guilty of bringing the scrum down.

They do look threatening Argentina, if they hadn't knocked on there it was a question of when not if they would score.

No maul this time but Argentina still look extremely threatening.

The speed of ball is lightning quick and scrum-half Tomas Cubelli thinks he's over for a try but he drops the ball.

Scrum to Wales five metres from their own try line.
