Argentina emerged comfortable 32-19 winners over South Africa in their Rugby Championship second round match in Mendoza to avenge their defeat at Kings Park Stadium a week ago.
Siya Kolisi crossed early on to launch the Springboks' challenge but they quickly fell apart in the face of an onslaught of tries aided by their fragile defence.
Bautista Delguy touched down twice and Nicolas Sanchez added a third as an impressive Argentina dominated the first-half.
South Africa were harried throughout and their set-piece never functioned, shortcomings compounded by their high error count.
At times in the second-half they hinted at a fightback with Lionel Mapoe claiming two tries, but Ramiro Moyano's score helped keep the Pumas out of reach.
