FULL-TIME: SOUTH AFRICA 38-21 ARGENTINA. South Africa get the win on the day, but it's New Zealand who walk away with the Rugby Championship by the finest of margins.
CONVERSION, SOUTH AFRICA, STEYN! 38-21
TRY, SOUTH AFRICA, ARENDSE! 36-21: The Boks get numbers down their right with Kriel creating space for Mapimpi, who passes out wide to Moodie, who offloads inside for Arendse to finish!
South Africa win a penalty off an Argentina scrum after a massive effort from the Boks pack.
PENALTY TRY, SOUTH AFRICA! 31-21! YELLOW CARD, ARGENTINA, SCLAVI: The South African rolling maul dominates and Sclavi is blown up for an infringement. Penalty try and a yellow card again!
CONVERSION, ARGENTINA, BOFFELLI! 24-21: Boffelli makes no mistake once again from the tee. The Rugby Championship is surely out of sight now for the Springboks.
TRY, ARGENTINA, MORONI! 24-19: Argentina use their numerical advantage to move the ball out wide and allow Moroni to stroll in for the try!
YELLOW CARD, SOUTH AFRICA, DE KLERK! 24-14: de Klerk is off too now for what is deemed cynical play, coming in from the side of the maul. Neither he nor Etzebeth looks satisfied with the reasoning behind their sin-binning.
YELLOW CARD, SOUTH AFRICA, ETZEBETH! 24-14: Etzebeth goes into the sin-bin for an off-the-ball push. Such an unnecessary yellow card for the Boks as the tension builds.
Just over 20 minutes left in the game and the Springboks' Rugby Championship hopes are hanging by a thread.
PENALTY TRY, SOUTH AFRICA! 24-14: That's better from South Africa, as they get the penalty try from the maul, and de La Fuente is in the sin-bin.
The clock is ticking and the Springboks have to extend their lead by 36 points and get a bonus point to win the Rugby Championship, which means they have to score at least three more tries.
CONVERSION, ARGENTINA, BOFFELLI! 17-14: Boffelli adds the extras with another great kick!
TRY, ARGENTINA, GONZALEZ! 17-12: Gonzalez sidesteps le Roux, leaving him for dead round the outside, and goes over for a try!
South Africa are struggling to stamp their authority on the second half. The clock is ticking and they need to change the tempo of this game.
KICK-OFF! Off we go for the start of the second half, with Argentina getting the game back underway.
CONVERSION, ARGENTINA, BOFFELLI! HALF-TIME: SOUTH AFRICA 17-7 ARGENTINA. The Boks go into the break 10 points ahead, needing to extend their lead by 29 points and secure a bonus point in order to surpass the All Blacks.
TRY, ARGENTINA, BETRANOU! 17-5: Boffelli is unable to finish off on Argentina's right flank, but Los Pumas recycle the loose ball through Gonzalez and Betranou eventually finishes off!
PENALTY, SOUTH AFRICA, STEYN! 17-0: Steyn knocks a penalty over from a long way out, keeping the scoreboard ticking. The Springboks have a strong mentality.
Argentina opted to go for touch, rather than posts, and the Springboks have managed to weather the storm, forcing Los Pumas to put the ball out.
Argentina win a penalty and kick for touch, then they catch the Boks unaware with a throw to the front. South Africa scramble on defence and Marx is penalised under the posts for a dangerous tackle.
CONVERSION, SOUTH AFRICA, STEYN! 14-0: Steyn puts the Springboks 14 points to the good.
TRY, SOUTH AFRICA, KOLISI! 12-0: It's the Springboks lineout maul which puts the pressure on and Kolisi peels away to score the Springboks' second try of the evening!
YELLOW CARD, ARGENTINA, GONZALEZ! 7-0: Argentina lose another player just as Kremer comes back on, as Gonzalez commits an infringement at the maul.
South Africa win a scrum penalty once again and Willie le Roux finds touch.
CONVERSION, SOUTH AFRICA, STEYN! 7-0: Clinical as ever, Steyn adds the extra two points.
TRY, SPRINGBOKS, WIESE! 5-0: The Springboks finally drive their way over with Wiese dotting down for a simple finish.
South Africa pile on the pressure, but they lose the ball forward and it abates. Argentina are given a team warning due to repeated infringements. We go back for a Boks penalty.
YELLOW CARD, ARGENTINA, KREMER! Kremer commits an infringement at the scrum and he is sent to the sin-bin. This is an opportunity for South Africa, who opt to go for touch rather than posts.
The Springboks are going to need to break the deadlock as soon as possible so that the floodgates open. Argentina are holding firm so far.
TRY DISALLOWED! From a lineout maul, Etzebeth thought he had scored for the Springboks, but the TMO rules that he took the ball from Kolisi from an offside position.
Bello is being treated on the field for an injury. Both teams are giving this everything in front of a packed stadium.
Steyn's kick is charged down, but the ball rolls beyond the dead-ball line. Scrappy start for the Springboks.
The Springboks get the game underway via Frans Steyn, the veteran who is starting today at flyhalf.
Australia's Damon Murphy is today's referee. Frank Murphy (Ireland) and Andrea Piardi (Italy) are his assistant and New Zealander Chris Hart is the TMO.
To win the Rugby Championship, the Springboks must beat Los Pumas by 39+ points & score at least three more tries than their visitors for a bonus point. If the Boks get a bonus win & match New Zealand on 19 points, points difference (PD) is the tiebreaker. If PD is also level, the Boks win on head-to-head PD, having beaten New Zealand by a greater margin in their opening fixture than the All Blacks beat them in their second.
