BUENOS AIRES (Reuters) - Lock Franco Mostert is the only change to South Africa’s team for Saturday’s Rugby Championship test against Argentina in Mendoza as coach Rassie Erasmus looks to repeat last weekend’s home win at the start of the southern hemisphere competition.

Mostert, who is headed to play for Gloucester this season after captaining the Lions to this month's Super Rugby final, comes in for Pieter-Steph du Toit in the starting lineup.
