Kinghorn replies twice for Scots
De la Fuente scores first try for home side

Rory Hutchinson
Scotland are right back in this!!
The forwards go through the phases, inching their way towards the line, before Blair Kinghorn demands the ball.
Edinburgh's fly-half has struggled at international level, but he shows all his quality here to race around Gonzalo Bertranou and find Rory Hutchinson with a lovely reverse pass.
The Northampton man dives over, and then Kinghorn adds the extras to level things up.
Argentina 18-11 Scotland
The errors are coming from Argentina now, and the home crowd is as quiet as they've been all game.
Scotland make their way into the home 22 again...
Mark Bennett
And they take that chance! Finally, a bit of attacking fluency from the visitors.
Rory Hutchinson, at first receiver, finds Blair Kinghorn out of the back, and he throws a flat, wide pass to the onrushing Mark Bennett.
Edinburgh's player of the season bursts through a hole to score Scotland's first try of this Test series.
Argentina 18-6 Scotland
This has been far better by Scotland.
They earn another penalty at the breakdown, which Blair Kinghorn again kicks into the corner.
Huge chance to get back in this game...
Argentina 18-6 Scotland
The ball goes loose from the lineout, Duhan van der Merwe reacts quickly, but can't quite dot the ball down and knocks-on.
Argentina then batter Scotland at the subsequent scrum, and clear their lines.
Fine margins.
Argentina 18-6 Scotland
Blair Kinghorn gets us back under way, and Scotland have an early chance...
Francisco Gomez Kodela is caught offside, and Scotland kick into the corner.
HT: Argentina 18-6 Scotland
Scotland have won five of their last six games in Argentina, and are unbeaten against Los Pumas since the 2011 World Cup.
They will have to come from behind here if that record is to continue.
HT: Argentina 18-6 Scotland
I've just seen a replay of Argentina's first try for the first time, and I'm 99.9% sure that Jeronimo de la Fuente didn't ground the ball.
Strange that it wasn't looked at.
All is forgiven, they've just shown another angle where he does ground the ball.

Quote MessageNot great from Scotland. No entries to the Argentina 22, and far too many errors - they've not got a foothold in the game.
Argentina 18-6 Scotland
The less said about that 40 minutes the better.
Still, things can only get better from a Scotland perspective.
Argentina 18-6 Scotland
Matt Fagerson gets over the ball at the breakdown and wins Scotland a vital penalty.
They just could not afford to concede again on the brink of half-time.
Argentina 18-6 Scotland
Someone in navy blue needs to get a grip on this game, and sharpish.
A loose pass goes to no-one, and Argentina are camped in Scotland territory again.
Santiago Carreras
Argentina go bang bang, and it's all a bit easy.
Juan Cruz Mallia gathers a clearance kick, and then scythes his way through the Scotland line.
Only a fantastic bit of scramble defence from Duhan van der Merwe stops the hosts scoring from that phase, but they get quick ball and Santiago Carreras dives over unopposed.
Jeronimo de la Fuente
The hosts force their way over from close range.
It looked like Ali Price had managed to hold Jeronimo de la Fuente up, but the home centre rolls over to score the game's first try.
Emiliano Boffelli drags the conversion well wide.
Argentina 6-6 Scotland
Guido Petti barrels his way into Scotland's 22 after a deft piece of handling from Francisco Gomez Kodela.
They are so close to the Scotland line.

Quote MessageWe're all hoping the fluency will come. This is Argentina's first Test for a long time. It's almost trying to iron out a few creases. For Scotland, the encouraging thing is that they are making ground from second phase onwards.
Blair Kinghorn
And Blair Kinghorn bangs it over.
Two from two for the Edinburgh man.
Argentina 6-3 Scotland
A neck-roll now gives Scotland the chance to level things up...
I can barely keep up with all these penalties.
Argentina 6-3 Scotland
Scotland are pinged once more by the referee - they need to reduce the penalty count big time.
They can breathe a sigh of relief though, as Emiliano Boffelli's first effort from the tee drifts wide of the right-hand post.
Argentina 6-3 Scotland
Nicolas Sanchez's day is done.
He is replaced at 10 by Santiago Carreras.
