Ghana-born winger Raymond Rhule scored his first international try, as South Africa claimed a 37-15 victory over Argentina in their Rugby Championship opener.
The Springboks dominated the physical contest, and scored tries through winger Courtnall Skosan, flanker Siya Kolisi and lock Pieter-Steph du Toit, their fourth victory in a row, after a 3-0 clean-sweep of France.
Argentina defended manfully and enjoyed little possession, but managed tries through experienced halfback Martin Landajo and winger Emiliano Boffelli.
The Springboks also handed a first cap to 20-year-old five-eighth Curwin Bosch, when he replaced Elton Jantjies late in the game.
"We couldn't have asked for a better start [to the competition]," said captain Eben Etzebeth. "We said, at halftime, we must keep going and the ball will break for us."
