The Springboks led Argentina 26-6 at the half-time break in their opening Rugby Championship match at FNB Stadium on Saturday.
Referee Chris Pollock awarded a penalty try 10 minutes before the break after Argentine hooker Eusebio Guinazo deliberately knocked an Adriaan Strauss pass down metres from the tryline. Guinazo also received a yellow card for his indiscretion.
Three minutes later JJ Engelbrecht went over for the second try of the match, with flyhalf Morne Steyn converting.
Steyn converted four penalties, while Argentina flyhalf Felipe Contepomi converted two of his attempts at goal. – Sapa
