Portugal's 4-1 win was secured by goals from Be Martins in the first period and Bruno Torres, Belchior, and André Lourenço in the second.

The match was marred halfway through the third period by German player Joscha Metzler suffering a nasty head injury after Portuguese player Leo Martins went for the overhead kick, only to connect with his opponent's skull.

In the day's early match, Switzerland laid down a challenge to reigning champions Portugal by beating France 10-2.
