Argentina scored nine tries by nine different players as they beat Namibia 64-19 in their final group game of the Rugby World Cup.
The Pumas went ahead thanks to a Juan Martin Hernandez try before a Santiago Gonzalez Iglesias penalty put the South Americans 10-0 up.
However, the Africans replied despite being reduced to 14 men after some sloppy Argentine defending allowed Johan Tromp to kick the ball over them and dive on the ball for a try.
The Argentinians would stomp out any hope soon after, with Matias Morini going over for an excellent solo score before three more tries from Horacio Agulla, Facundo Isa and Lucas Noguera put them 36-7 ahead at half time.
Namibia gave themselves a glimmer of hope just after the break as JC Greyling seized on some poor passing to go through alone to score his nations' second try of the afternoon.
That hope was short-lived as Argentina would reply quickly again, with Matias Alemanno powering over the line after a strong scrum.
Leonardo Senatore finished off another classy move from the Pumas for their seventh try before Julian Montoya and Tomas Cubelli compounded their advantage with quick tries within five minutes.
Eugene Jantjies scored a late consolation try for Namibia and the nation allowed retiring prop Johnny Redelinghuys to take the attempt but the big man's kick fell short.
Argentina had already qualified from Pool C before the game and will now take on either France or Ireland in the quarter-finals.
