Captain Felipe Contepomi kicked 17 points to help Argentina to a 22-14 win over Italy at Turin's Stadio Olimpico on Saturday.
Rafael Carballo ran in the Pumas only try in the 50th minute after fly-half Juan Martin Hernandez collected his own clever chip in the middle of the pitch to feed the winger.
Fly-half Andrea Marcato scored two penalties and a drop goal for the Azzurri and fullback Andrea Masi ran over a consolation try in stoppage time.
The result eased the pressure on Argentina coach Santiago Phelan, giving his side their second win since he took over after last years' third-place finish at the World Cup.
