South Africa made it two wins out of two in the Rugby Championship after they beat Argentina 41-23 at Estadio Padre Ernesto Marlearena.
Crossings from Siya Kolisi (2), Elton Jantjies and Jean-Luc du Preez as well as a penalty try saw the Springboks to an impressive victory.
In reply the Pumas' scores came from Ramiro Moyano and Matias Moroni but they were hindered by a red card from lock Tomas Lavanini.
Argentina took an early lead on four minutes when wing Emiliano Boffelli showed off his powerful boot following a ruck penalty. That shot from 55 metres though should've been chalked off by Jantjies but the Springbok fly-half missed with his first two kicks soon after.
It took until the 20th minute for the game's first try and it went the way of South Africa and Jantjies was the provider, his chip kick on halfway finding Jesse Kriel whose offload to Kolisi saw the flanker go in untouched. Jantjies would make no mistake from in front for 7-3.
Jantjies made it 10-3 seven minutes later with a penalty but the visitors' joy was shortlived when the restart was allowed to bounce and Pumas wing Moyano duly gathered for a gift wrapped try. Juan Martin Hernandez made no mistake off the tee and the game was locked up at 10 points each.
South Africa came close to striking straight back through Andries Coetzee but Kolisi's pass was adjudged to be forward so it was disallowed.
They wouldn't be denied though on 39 minutes when Jantjies slipped a tackle and reached out for a try to make it 17-10 at the turnaround.
After the interval Hernandez cut the lead to four points with a penalty on 45 minutes before good interplay between Coetzee and Courtnall Skosan after a turnover set up a second try for Kolisi. Once again the final pass to Kolisi came from Kriel as the Springboks led 24-13.
Then came Lavanini's second yellow card for a deliberate knock down and that was compounded by a penalty try being given, making it 31-13.
On the hour mark the Pumas hit back through Joaquin Tuculet's converted try and with a Boffelli penalty they were only trailing by eight.
With eight minutes remaining though a Jantjies penalty made it 34-23 before replacement Du Preez made sure of an impressive away victory.

The start of the game was delayed by 20 minutes due to the lights having gone out at the stadium prior to kick-off.
Tries from Courtnall Skosan, Raymond Rhule, Siya Kolisi and Pieter-Steph Du Toit proved too much for Argentina who scored through Martin Landajo and Emiliano Boffelli.
In a fast-paced encounter, in which both sides stayed true to their attacking roots, the All Blacks' superior game management — especially in the first half — laid the groundwork to this win and they eventually outscored the Wallabies seven to four.
In a pulsating contest, in which the result was in the balance until the end, there was controversy in the game's closing stages when referee Romain Poite ruled that Lions replacement hooker Ken Owens had played the ball from an accidental offside position.
Tries from Taulupe Faletau and Conor Murray as well as 14 points from Owen Farrell's boot proved too much for the All Blacks who scored through seven penalties from Beauden Barrett.
Argentine tries from Agustín Creevy, Joaquín Tuculet and a Ramiro Moyano hat-trick proved too much for Georgia who scored through Davit Kacharava, Shalva Mamukashvili and a penalty try.
Springbok tries from Jesse Kriel, Eben Etzebeth, Malcolm Marx and Rudy Paige proved too much for France who got on the board courtesy of four penalties from Jules Plisson.
There was plenty of hype in the build-up to this Test and that was certainly justified as both sides went at each other hammer and tongs for the full 80 minutes.
Five tries were scored by Joe Schmidt's men as Garry Ringrose, Josh van der Flier, Kieran Marmion, Rhys Ruddock and Sean Reid crossed.
After suffering a shock defeat to Scotland in Sydney last week, the Wallabies were determined to secure this result but they only achieved that goal late in the second half after staving off a brave fightback from the Azzurri.
Ben Volavola was his side's hero as he finished with a 17-point haul, thanks to five penalties and a conversion, although Scotland outscored the Pacific islanders by three tries to two.
Two tries from Steff Evans proved the difference while Sam Davies slotted three penalties as the Samoans came up just short at home.
USA take on Canada on June 24 in Hamilton, Ontario, and on July 1 in San Diego, California, as they look to book a spot in the tournament.
Canada kicked three penalties from Gordon McRorie but also had two tries disallowed in a fierce game that saw a red card and two yellows.
Tries from Charlie Ewels, Piers Francis, Danny Care and Will Collier helped them to the success, with George Ford contributing 15 points.
The Springboks have now taken an unassailable 2-0 lead in the series after last week's 37-14 victory in Pretoria with the final match to take place next weekend in Johannesburg.
Leigh Halfpenny finished with 20 points as the Lions scored second half tries through a penalty try and second-row Maro Itoje, having completely dominated after half-time as the Maoris failed to add any points.
Keith Earls, Dan Leavy and Jack Conan all finished with braces for Joe Schmidt's side, with Garry Ringrose the other try scorer for Ireland.
