(CNN) -- World rugby champions South Africa thrashed Argentina 63-9 in a one-off Nelson Mandela Tribute Test match at Johannesburg's Ellis Park on Saturday.
South Africa wing J.P. Pietersen went over for two of his team's nine tries against Argentina.
The Springboks, who beat the visitors in the semifinals of last year's World Cup, led only 14-9 at the halftime break but went on to run in nine tries.
Winger J.P. Pietersen and replacement forward Joe van Niekerk both went over the Pumas' line twice, while flyhalf Butch James added the extras for every single score.
Argentina captain Felipe Contepomi kicked three penalties, putting his side 9-0 ahead in the first 25 minutes despite the early loss of tighthead prop Patricio Ledesma.
Adrian Jacobs scored the first of South Africa's tries in the 33rd minute after break by his midfield partner Jean de Villiers, and two minutes later debutant winger Jongi Nokwe sprinted across the line.
No. 8 Pierre Spies added the third try soon after the break, then Pietersen's first try made it 28-9.
Springboks coach Peter de Villiers then made several changes, bringing on World Cup stars Fourie du Preez and Jaque Fourie.
Scrumhalf Du Preez pounced on a loose ball to score the Boks' fifth try but center Fourie went off with 20 minutes left after sustaining a serious cheekbone injury.
But backrower van Niekerk came on to mark his 50th outing for South Africa with a brace of tries, while Bismarck du Plessis and Pietersen also went over.
South Africa now return to the final rounds of the Tri-Nations tournament, with leaders New Zealand visiting Cape Town next weekend and Australia coming to Durban and Johannesburg in the following fortnight.
