South Africa came straight off a series win over the British and Irish Lions to beat Argentina 32-12 and join the All Blacks as winners in the opening round Rugby Championship.
The Springboks scored three tries, through starting scrumhalf Cobus Reinach, wing Aphelele Fassi and replacement scrumhalf Jaden Hendrikse, to neutralise an Argentina team that relied on the boot of Nicolas Sanchez for all their points.
Flyhalf Elton Jantjies kicked 17 points for the Springboks, who made 10 changes to the starting lineup that clinched the series against the Lions a week ago. Captain Siya Kolisi, lock pairing Eben Etzebeth and Lood de Jager, No 8 Jasper Wiese and Reinach were the only ones retained.
South Africa fielded a new backline outside Reinach.
Reinach set the Springboks on their way with a try off turnover ball in the 13th minute. He scooped up a loose Argentina pass deep inside South African territory and raced away to score in the left corner, just evading an attempted cover tackle from Rodrigo Bruni.
