Nicolas Sanchez has celebrated his 100th cap in style, with a try and a flawless kicking performance, as Argentina set up a World Cup Pool D decider against Japan with a brutal 59-5 demolition of Chile.
First-five Sanchez scored five and kicked 15 points to become his country's topscorer at a World Cup, adding to tries by Juan Martin Gonzalez (2), Agustin Creevy, Martin Bogado, Rodrigo Isgro, Ignacio Ruiz and Santiago Carreras to put Argentina in second place on nine points.
Argentina lead third-placed Japan on points difference before their meeting next week, with a quarter-final spot at stake, while Chile exit the tournament bottom of the group with zero points, despite scoring a late try through Tomas Dussaillant.
Pool D leaders England have qualified in top spot.
At Nantes' La Beaujoire Stadium, Sanchez - already the team's all-time topscorer with 872 points - put Argentina ahead with an early converted try, diving over, after a nice dummy.
He added a penalty, before No.8 Gonzalez crossed from a maul, as did hooker Creevy for the Pumas' third, midway through the opening half.
Rodrigo Isgro's yellow card for a high tackle on Rodrigo Fernandez slowed Argentina's progression and no other points were scored before halftime.
Having nothing to lose, Chile came back from the dressingroom with a very offensive mindset, but were caught cold, when Bogado beat Inaki Ayarza's tackle for Argentina's fourth try.
The crowd went wild, when Chile's Augusto Bohme touched down, after a clever lineout, only for the try to be ruled out for a forward pass.
Argentina were ruthless, Isgro adding another try, as he dotted down under the posts, before Gonzalez claimed a double.
Dussaillant finally put Chile on the scoreboard to send their many fans wild, but they faced a brutal backlash, as Ruiz and Carreras crossed to complete Argentina's crushing win.
