South Africa could seal their first Rugby Championship since 2009 with a win against Argentina on Saturday, but Pumas centre Jeronimo de la Fuente said his team will aim to take advantage of their rivals' confidence that they can win the title.
The emphatic win gave the unbeaten Springboks a bonus point and a total of 12 points from their three matches, four more than second-placed Australia who earlier on Saturday stunned reigning champions New Zealand 47-26 in Perth.
Handre Pollard of South Africa scores a try during their big win over the Pumas.
Flyhalf Pollard scored two of South Africa's five tries, five penalties and three conversions for 31 points - his best career haul - to help the Springboks to a fourth southern hemisphere title.
"We played the best teams in the southern hemisphere so it is good to have this one step up, although a lot of work still needs to be done before the World Cup".
Argentina have lost both their games, while the Springboks beat Australia and drew with New Zealand.
Cordero gathered a perfectly weighted cross kick from Nicolas Sanchez and held off Makazole Mapimpi to dive over in the corner.
"It is going to be very hard, South Africa have great players who are very physical", De la Fuente added.
Pollard reduced the deficit off a ninth-minute penalty and the visitors went in front soon after when Bongi Mbonambi scored off a rolling maul after a lineout.
The opening half then became a goal-kicking battle between playmakers Pollard and Sanchez with the SouthAfrica kicking three penalties and converting his try in the final minute of the half.
The Springboks' progress slowed early in the second half when scrumhalf Faf de Klerk was sin-binned, only for Pollard to cross again.
They struggled at first to use the ball effectively in outside channels, but that changed in the second half as they played with more confidence and combination while Argentina visibly exhausted.
"It hurts us all, in our country. but there's still a month of work before the World Cup and we mustn't lose sight of our focus".
