Warriors duo Agustin Creevy and Leonardo Senatore were both in international at the weekend for Argentina but couldn’t prevent the Pumas from a 41-31 loss to Scotland.
Both players started for their country, who took the lead within two minutes when flanker Javier Ortega Desio scored but Scotland's Gray brothers (Richie and Jonny) then took centre stage to mark their first Test match together with a try each.
Sean Maitland then finished off a fine break by scrum-half Greig Laidlaw, and it was the Gloucester man who then added a penalty to his conversions giving Scotland a 24-10 lead at half-time.
Laidlaw then found Stuart Hogg to add a fourth try but the Pumas fought back.
The forwards forced a penalty try before Tommy Seymour snatched an interception to extend Soctland's lead.
Argentina finished with a flurry as replacement scrum-half Tomas Cubelli crossed the whitewash twice but it was Scotland's day at Murrayfield.
