South Africa are eager to seize the moment and clinch the Rugby Championship title in Argentina on Saturday, but are wary of a fired-up home side that are not out of contention themselves, according to Springboks loose forward Kwagga Smith.

Argentina secure a dramatic win against South Africa to stop the world champions from winning the Rugby Championship title with a game to spare.

With a return fixture to come next week, Erasmus has rested a couple of key figures, with Siya Kolisi in the coaches’ box rather than on the pitch as he manages a facial injury. Argentina may therefore spy an opportunity to cause a shock — the hosts are full of confidence after producing a record win against Australia a fortnight ago.

Manie Libbok’s missed penalty with a minute remaining meant that Argentina continued their excellent Rugby Championship campaign by adding a win over South Africa to their record victory over Australia and triumph in New Zealand earlier in the tournament.
