South Africa 24 Argentina 18
Wing S’busiso Nkosi scored two excellent solo tries as much-changed South Africa survived a scare to beat Argentina at Loftus Versfeld.
Springbok fly-half Elton Jantjies also kicked 14 points in a scrappy World Cup warm-up.
Argentina scored tries through lock Guido Petti and captain Pablo Matera and could have had more were it not for poor handling at vital times as they fell to a ninth successive Test defeat.
The Boks fielded a completely new XV from those who thumped Argentina 46-13 in Salta the week before to lift the Rugby Championship. The visitors made 10 changes.
After the teams traded penalties, the opening try came in simple fashion. The Boks threw the ball wide for Nkosi, whose dancing feet and raw power saw him beat two defenders and dot down. But Argentina grabbed the half-time lead after the hooter as scrum-half Cobus Reinach’s pass was intercepted by Petti for a 10-8 advantage.
More magic from Nkosi punished Argentina as he collected the ball out wide and beat four defenders to cross in the corner.
The teams traded penalties and with 20 minutes left the Boks led 18-13, but Argentina scored their second try as Matera barged over after a line-out.
Jantjies landed a 50-yard penalty before Argentina thought they had stolen the lead when they had the ball over the tryline, but TV match official Simon McDowell disallowed the score for an earlier obstruction.
