Mateo Carreras, Pablo Matera and Joel Sclavi all forced their way over the line before a excellent dummy from Tomas Albornoz sent Argentina ahead. With Arendse restored just a few minutes before the break, Cobus Reinach sprinted in for a try and made it a four-point game heading into the second half.

The Boks have never won six in a row in the Rugby Championship, and they've never won the tournament with a match to spare, but they have the opportunity to achieve both of these feats against Argentina in Santiago del Estero on Saturday and turn next weekend's finale against the Pumas in Nelspruit into a celebratory affair.

Argentina have now beaten all three Rugby Championship opponents after they triumphed over the Springboks 29-28 in Santiago. The hosts scored four tries on the day with Mateo Carreras, Pablo Matera, Joel Sclavi and Tomas Albornoz scoring with the fly-half also kicking three conversions and a penalty in an epic shift.
