Ilya Bryzgalov had an easy shutout, making 15 saves.

Sweden came back after losing to Switzerland the previous day and held off the Czech Republic 2-1 in Stockholm.

Also, Finland beat Slovakia 2-0 for its second win, Norway defeated newcomer Slovenia 3-1, and Canada topped Denmark 3-1.

Finland won behind a 36-save shutout performance by goaltender Antti Raanta.

In Stockholm, Norway beat Slovenia behind two goals from Anders Bastiansen.
