Ex-Leinster fly-half Felipe Contepomi leads an experienced Argentina against Wales in Saturday's World Cup warm-up.
The Pumas team for Cardiff includes seven members of the squad that finished third in the last World Cup.
Argentina are without star back Juan Martin Hernandez, out of the World Cup with a knee injury, and centre Gonzalo Tiesi, who is nursing a shoulder knock.
But winger Horacio Agulla, hooker Mario Ledesma and number eight Juan Fernandez Lobbe all start.
This is the first time Argentina's professional players have been together since their European tour last November, when they lost to Ireland and France after beating Italy.
The Pumas have a second warm-up match against Worcester before taking on England and Scotland in their World Cup pool next month.
