Santiago Gonzalez Iglesias kicked a late penalty as Argentina gained revenge for last week's Rugby Championship defeat to South Africa by claiming a 26-24 victory over the same opponents in Salta.
The Pumas appeared to be letting another 10-point lead slip through their fingers, like they did in the final 15 minutes to lose 30-23 in Nelspruit last week, but this time they made home advantage count courtesy of Gonzalez Iglesias' 78th-minute three-pointer.
The win was only their second over the Springboks in 24 meetings and condemned Allister Coetzee to defeat in his first overseas Test as South Africa coach.
Nicolas Sanchez kicked two penalties, after Elton Jantjies booted the visitors ahead, and converted Joaquin Tuculet's superb try to give Argentina a 13-3 half-time lead.
South Africa came out fighting in the second half, levelling courtesy of another Jantjies penalty and a Bryan Habana try, only for Argentina to open up a 10-point lead after Juan Martin Hernandez produced a brilliant cross-field kick for Juan Manuel Leguizamon to score and then booted a conversion and a penalty.
Morne Steyn kicked two penalties either side of a 68th minute Pieter-Steph du Toit try to move South Africa 24-23 ahead, but Gonzalez Iglesias had the final say for Argentina.
