Rugby Championship: Wallabies savaged by Pumas after epic All Blacks win over Springboks

Wallabies coach Dave Rennie is frank with his assessment on Stan Sport.

"Massive disappointment. It's not good enough," Rennie said.

"We conceded four tries with kicks in behind us and got dominated in collisions. We definitely lacked cohesion. There was a few changes but we're better than that.

"We want to earn the respect of the country and you don't do it with performances like that.

"We had a good enough side on the paddock to do the job. We've got to be better.

"We know we'll get a few guys back (against South Africa in Adelaide) but whoever puts the jersey on has got to front."

What a wonderful day for Argentinian rugby as Tomas Albornoz scores an incredible try to seal a record 48-17 win over the woeful Wallabies.

Incredibly, that puts Los Pumas on top of the Rugby Championship after two rounds and has completely taken the wind out of Australia's sails.

The undermanned Wallabies must lick their wounds and return home to prepare for a date with the world champion - and also stinging - Springboks in Adelaide on August 27.

"Clearly disappointed, that probably fell short of standards," stand-in Wallabies captain James Slipper said.

"They're a tough team to play catchup footy against. Every (Rugby Championship) team has won one now and we're excited to go home for two games against South Africa. Looking forward to playing in front of our fans."

Emiliano Boffelli has done it with the boot, now he does with five points as he collects a delicate Lucio Cinto kick to score yet another Pumas try.

Argentina lead 41-17 after 79 minutes as we search for the record books.

You would think it's too little, too late but Wallabies centre Len Ikitau has pegged one back by dotting down next to the sticks.

Argentina lead 36-17 after 67 minutes.

Surely this is curtains for the Wallabies as prop Thomas Gallo grabs a double despite what appears to be a clear double movement.

The try stands and the Pumas lead 36-10 after 64 minutes.

Ugly reading for Australian fans.

Emiliano Boffelli has become one of the better goalkickers in Test rugby.

He nails another tricky penalty and the Wallabies are in big trouble.

The Pumas lead 29-10 after 54 minutes as Tate McDermott and Nick Frost enter the fray as Dave Rennie searches for a spark.

Time to catch our breath after a wild 40 minutes in San Juan.

Argentina lead 26-10 at halftime.

"That was ridiculous," Nick McArdle says on Stan Sport.

Australia have a lot of work to do.

Wallabies squad member Jake Gordon says the team are struggling to deal with Argentina's contestable kicking game.

What a player Marika Koroibete is.

The winger saves the day for the Wallabies with a freakish try saving tackle on Emiliano Boffelli.

It looked like Boffelli may have grounded the ball before losing it but the TMO and referee decide there is no compelling evidence to overturn the initial knock on call.

Phew! The Pumas lead 26-10 after 38 minutes.

This is madcap rugby two weeks in a row as Juan Martin Gonzalez scores another for Argentina.

The Wallabies failed to deal with another kick and the Pumas are punishing all of their errors.

The hosts lead 26-10 after 32 minutes... can the Wallabies dig themselves out of yet another hole?

Argentina rub salt into wound as Jeronimo de la Fuente runs over for a bizarre try.

It looked like de la Fuente pulled a hammy while scoring but he was able to muster the energy to score.

De la Fuente now leaves the field as the Pumas lead 21-10 after 26 minutes.

"I wonder why he stopped running," referee Karl Dickson says.
