Argentina stood firm against a powerful Tonga in Pool C to take a giant stride towards the World Cup quarter-finals.

A ferocious early Tonga onslaught laid the platform for Kurt Morath's try.

But Joaquin Tuculet and Juan Imhoff crossed as Argentina established a 20-13 half-time lead.

Soane Tonga'uiha's try reduced the gap to seven points but Nicolas Sanchez, who also kicked 20 points, darted over and Julian Montoya and Santiago Cordero tries rounded things off.

The Pumas have won two of their three group games and sit in second place behind New Zealand.
