Argentina coach Santiago Phelan has made two changes to his line-up for Saturday's Rugby Championship clash against Australia.
The Pumas will use the same forward pack that strongly tested New Zealand before going down 21-5 but make changes at the key scrum-half and full-back positions.
Martin Landajo has been named at No.9 ahead of Nicolas Vergallo with Lucas Gonzalez Amorosino replacing Martin Rodriguez at full-back.
Lock Patricio Albacete has been named to play his 50th Test, lining up against Nathan Sharpe who will captain Australia in one of his final appearances.
Argentina are yet to win in their inaugural campaign in the Southern Hemisphere tournament after a loss and a draw against South Africa and a defeat by New Zealand.
Argentina: 15 Lucas Gonzalez Amorosino, 14 Gonzalo Camacho, 13 Marcelo Bosch, 12 Santiago Fernandez, 11 Horacio Agulla, 10 Juan Martin Hernandez, 9 Martin Landajo, 1 Rodrigo Roncero, 2 Eusebio Guinazu, 3 Juan Figallo, 4 Manuel Carizza, 5 Patricio Albacete, 6 Julio Farias Cabello, 7 Juan Manuel Leguizamón, 8 Juan Martin Fernandez Lobbe (captain).
Replacements: 16 Agustin Creevy, 17 Juan Pablo Orlandi, 18 Leonardo Senatore, 19 Thomas Leonardi, 20 Nicolas Vergallo, 21 Martin Rodriguez, 22 Juan Imhoff
