Argentina head coach Daniel Hourcade was left to rue his side's mistakes late on in Nelspruit after their late defeat to South Africa.
Los Pumas led by ten points after Santiago Cordero's try, only for scores from Johan Goosen and Warren Whiteley to deny Argentina a second-ever win over the Springboks.
Hourcade was pleased however with elements of his team's performance, including their defence.
"It made sense that South Africa would throw everything at us in the final stages, and they did. That was the only moment in the game when we made mistakes that cost us the game," Hourcade said.
"Matches last 80 minutes and we couldn't close it.
"We had a solid defence which put a lot of pressure on their key players to stop them from playing how they wanted to.We were good at the breakdown and that along with our defence were our key weapons.
"The ball was difficult and slippery, so we couldn't play as much as we wanted to. It was generally an even contest."
The two teams will face off again next week in Salta, with Hourcade expecting an improved South African side.
"We played well today, but next week will be much harder. There are things to correct and others that we have to repeat to prevent South Africa from playing how they want to."
