Argentina reaffirmed its supremacy in the Americas when it completed its campaign by beating the United States 47-17 in Kumagaya.
The first team to finish its pool matches, the Pumas fell short of a fourth consecutive quarterfinal berth but will head home with a consolation automatic qualification for the 2023 tournament in France by finishing third in Pool A in Japan.
They hadn't met the United States in 16 years, when the Pumas won 42-8 in Buenos Aires, and eclipsed that record scoring seven tries to three.
