Tour Match Argentina 19-21 Scotland

Duncan Weir scored a late penalty to see off Argentina as Scotland secured their third Test win on the spin under new head coach Vern Cotter.

Stuart Hogg scored a first-half try before Javier Ortega Desio ran over to give the Pumas a half time lead.

The hosts took charge after the break through the boot of Nicolas Sanchez's kicking and Joaquin Tuculet's try.

But Henry Pyrgos crossed late on and Weir held his nerve to win it with his third successful penalty.

Scotland had already beaten USA and Canada on the four-match tour and they take on South Africa next Saturday.

Cotter's inexperienced side, captained for the first time by Grant Gilchrist, were shaky in the opening stages but began to push the Pumas back, with Hogg looking lively.

Nicolas Sanchez was in great form for the Pumas

And they grabbed the lead in the 6th minute, Nick De Luca's excellent pass sent Tommy Seymour scampering down the left and he fed Hogg to go over in the corner, with Weir converting.

Seymour went close again soon after, following his own kick down the left only to be denied by a bad bounce.

The hosts went straight up the pitch and scored a try of their own. Santiago Iglesias sparked the initial counter on the right and after a great spell of possession Desio dived over on the left. Sanchez was unable to add the extras from out wide.

Argentina were having all sorts of problems at their own line-outs, gifting possession back to the visitors, who were attacking with real promise but falling short in the final third.

And they fell behind in the 27th minute when Sanchez banged over a delightful drop goal.

The fly-half began to boss proceedings with some pin-point work with the boot, paving the way for a period of dominance for the hosts. He was, however, just off target with another drop goal attempt.

Ross Ford, on the night he became Scotland's most capped hooker, helped steady the ship for Cotter's side but they passed up the chance to take a lead into the break when Weir's penalty drifted narrowly wide.

It was 11-7 after two minutes of the second half when Sanchez knocked over a penalty.

Cotter's troops enjoyed another spell of decent possession but were unable to break through and had to settle for a penalty, scored by Weir to take his side within a point of the Pumas.

Scotland gave away another penalty for failing to release at the breakdown and Sanchez scored from the half-way line with a superb kick.

The hosts quickly built on that advantage when substitute Tuculet showed a great turn of pace to cross on the left but Sanchez could not convert.

Seymour, so impressive in spells the first half, got going again in the 63rd minute on the left to earn good field position but the home defence stood solid and turned the ball over.

The Scots were struggling to put phases together but a monster penalty from Weir brought them within six points with just under 10 minutes to play.

And sub Pyrgos reduced their arrears to a 19-18 when he ran over following fine work by De Luca and Seymour down the left. Weir, however, missed the chance to give his side the lead.

The Glasgow Warriors fly-half had the chance to make amends with a 78th minute penalty and he made no mistake, crashing the ball straight over the posts, amid a chorus of boos from the home fans, for a 21-19 lead.

Sanchez then missed a last-gasp drop goal as the Scots snatched the win.

And they now head to Port Elizabeth next Saturday to take on the Springboks.
