Wallabies secure historic series win over Argentina with dramatic penalty try draw

The Wallabies have snatched a 28-28 draw with Argentina in Mendoza after they were awarded a penalty try with 10 minutes remaining in the Test.

Trailing 28-21, the Wallabies were on the attack inside the Pumas' 22 when the home side's fullback Santiago Carreras deliberately knocked the ball on in defence.

Referee James Doleman felt he had no other option but to award the Wallabies a penalty try.

Carreras was shown a yellow card for his infringement only a minute after teammate Lucio Cinti committed the same offence and was sent from the field for 10 minutes.

Neither side could break the deadlock in the shadows of full-time, meaning the Wallabies secured a history-making 1-0 series win.

The Wallabies had previously never won a multi-Test series on Argentine soil.

The result also left new coach Les Kiss with an unbeaten record (three wins and a draw) since taking over from Joe Schmidt.

It was an unconvincing performance from the Wallabies, who had led 14-0 following converted tries to captain Harry Wilson and Max Jorgensen in the first half.

The Pumas responded before the half-time break with tries to skipper Pablo Matera and Ignacio Mendy, both of which were converted by Carreras.

It was 14-14 at half-time, before the Wallabies broke the deadlock with Fraser McReight's try from close range in the 47th minute.

Ryan Lonergan added the extras but it was a short-lived lead after the Pumas responded through converted tries to Ignacio Ruiz and Matera.

The Pumas held their advantage until Carreras's indiscretion late in the match.

The Wallabies, who won the opening Test 27-21 in Jujuy, now have three weeks to prepare for their next clash.

They face world champions South Africa in Perth on September 27.
