Dragons scrum half Gonzalo Bertranou was a second half replacement as Ireland cruised past ill-disciplined Argentina to claim their eighth straight win and secure a clean sweep in the autumn Tests.
Having fallen behind to a Mateo Carreras try early on, the hosts powered ahead with scores from Josh van der Flier, Andrew Porter and Caelan Doris.
Argentine Pablo Matera was sin-binned and team-mate Tomas Lavanini sent off as Van der Flier and Dan Sheehan extended Ireland's lead.
Home duo Cian Healy and Tadhg Beirne completed the rout as Ireland chalked up a convincing 53-7 win.
