Argentina scored eight tries in a 59-5 bonus-point win over a spirited Chile in Nantes, setting up a crunch Pool D fixture against Japan next week for a quarter-final spot.
The fly-half Nicolás Sánchez opened the scoring in his 100th Test match with a fine individual try, before Juan Martín González and the veteran hooker Agustín Creevy rolled over the line on the back of mauls as Argentina took charge of the first ever all-South American Rugby World Cup contest.
