Boks have it all to play for against Pumas as Rugby Championship remains alive

Critical showdown between South Africa and Argentina for last round berth.
The All Blacks’ failure to secure a winning bonus point against Australia in their combined Rugby Championship and Bledisloe Cup clash in Melbourne on Thursday has raised the stakes in Buenos Aires.
It means that whichever of the Pumas and the Springboks could earn maximum points in tomorrow’s encounter will go into the last round with a realistic chance of winning the title.
Had the All Blacks secured a bonus point against the Wallabies in their dramatic 39-37 win, they would have had nine fingers on the trophy.
As it is, they have 14 points on the standings with the Boks and Pumas on nine each. A bonus point win in Buenos Aires would draw the Boks level with the All Blacks with a home game against Argentina to come.
The All Blacks, of course, are also at home in their final fixture — at Eden Park in Auckland against the Wallabies. They haven’t lost there since 1994.
New Zealand are certainly in pole position now after their dramatic win over Australia through an 81st minute try from Jordie Barrett following a controversial refereeing decision.
Matters in Australasia though, are secondary to needs in Buenos Aires. Both the Pumas and the Boks know that this is a semi-final. There is no next week.
Steady hand
Bok coach Jacques Nienaber chose the same starting XV that beat Australia 24-8 in Sydney two weeks ago, but there were three changes on the bench.
The decision to select the same starting XV is a clear sign that the experimentation of earlier in the season has given way to the more prosaic needs of winning and building combinations.
But there are some minor tweaks on the bench.
Scrumhalf Faf de Klerk returns after missing out in Sydney with Cobus Reinach in the stands this week. Elrigh Louw is the loose forward replacement, coming in for Duane Vermeulen and big centre Andre Esterhuizen makes a return in place of Warrick Gelant.
Pumas coach Michael Cheika unsurprisingly made wholesale changes after his side lost 53-3 against New Zealand, a week after securing a historical first win over the All Blacks in that country.
Cheika decided to change both props, with Eduardo Bello introduced at loosehead and Nahuel Tetaz Chaparro at tighthead as Thomas Gallo and Joel Scalvi drop to the bench.
There are two more changes in the pack with Matias Alemanno recalled at lock and Juan Martin Gonzalez picked ...
