Sean Maitland has scored a try 15 minutes from time to earn Scotland a hard-fought 14-9 victory over a profligate Argentina at Murrayfield and end the year on a winning note.
The winger was sent over on the blind side by Stuart Hogg after a smart piece of thinking that brought to life a dour tussle on Saturday.
Greg Laidlaw kicked three penalties for Scotland but Nicolas Sanchez miss four out of seven kicks for the Pumas.
Scotland were 6-3 ahead at halftime as Argentina suffered a fifth successive test defeat which has included losses in Ireland and France during their November tour programme.
For Scotland it was a second victory in four internationals this month, having beaten Fiji but losing away to Wales and at home last weekend to South Africa.
