Argentina finished their World Cup with a bonus-point win over the USA as they came third in Pool C and confirmed a spot at the 2023 tournament.

The Pumas, who have failed to reach the knockout stages for the first time since 2003 after defeats by France and England, crossed for seven tries.

Joaquin Tuculet scored a first-half double after Nicolas Sanchez's opener.

The USA responded before the break when Blaine Scully touched down from fly-half AJ MacGinty's clever grubber.

But centre Juan Cruz Mallia crossed twice to reassert Argentina's dominance in the second half, with further scores from Jeronimo De La Fuente and Gonzalo Bertranou.

Paul Lasike responded with a try and Scully added a late third for the USA, who finish their campaign against winless Tonga on Sunday.

A third-place finish in the pool stages in Japan guarantees teams a place at the World Cup in France in four years' time.
