A second-string Springboks team beat Argentina 24-18 in a Rugby World Cup warmup test which would have given both team's preparations a different complexion if the Pumas hadn't had a late try disallowed.
Lucas Mensa's score in the 77th minute would have put Argentina ahead 23-21 with a conversion to come — and very possibly given Argentina just its second win over the Boks in South Africa — but the midfielder was ruled out for an obstruction early in the counterattack.
Instead, South Africa first-five Elton Jantjies kicked the resultant penalty down the other end of the field to seal victory and finish with 14 points off the tee. Wing S'busiso Nkosi scored a try in each half to help keep the Springboks unbeaten this season with one more warmup test to come before the World Cup in Japan.
South Africa's frontline players were given a rest by coach Rassie Erasmus after they crushed Argentina 46-13 in Salta a week ago to win a curtailed Rugby Championship. Erasmus didn't start any first-choice players at Loftus Versfeld except captain Siya Kolisi, who returned from injury for his first test this season.
Some of the starting 15, like 38-year-old hooker and captain Schalk Brits, are probably third in line in their positions — but the Springboks reserves did enough.
