Ireland scored seven tries in a 46-24 record demolition of Argentina in Dublin to ensure they will be seeded when the draw is made next month for the next Rugby World Cup.
The 22-point thrashing at Lansdowne Road ensures Ireland secure their place as a second-tier nation ahead of next month's Cup draw, while the South Americans are left waiting to find out if they will join them.
Argentina, who got two late consolation tries, will slip out of the world's top eight and the Pumas face a potentially tougher World Cup pool draw if Samoa beat France later on Saturday and Wales defeat either New Zealand or Australia this weekend and next.
If the in-form Samoans lose by fewer than 15 points, they will tie with Argentina on 78.71 ranking points, with the higher-placed team determined by the next decimal place.
