Scrumhalf Cobus Reinach was one of those squad members who would’ve wanted to catch Erasmus’ eye, but perhaps because he was trying too hard, he wasn’t quite at his best.
Apart from a line-break in the first half, Reinach took one too many steps when clearing the ball, and seemed hesitant in his decision-making.
It eventually cost him and the team as he held on to the ball too long just before halftime, and threw a speculative pass that was intercepted by Argentina lock Guido Petti, who had enough pace to score.
Suddenly Los Pumas led 10-8 at halftime, and the South Africans needed to regain their spark to avoid an untimely defeat ahead of the World Cup.
And it was that man Nkosi who came up with the decisive play. The Sharks star was in space on the right, but had a number of defenders in front of him. No problem, though, as he stepped and then powered his way through for his second five-pointer of the night.
