Connor McDavid scored three power-play goals and Canada clinched first place in its group with a 6-0 rout of Sweden on Tuesday at the world under-18 hockey championship in Sochi, Russia.

McDavid opened the scoring 1:17 into the game, and sealed the victory with a pair of goals in the third period.

The 16-year-old Erie Otters forward, who added an assist, has 11 points in four games at the tournament.

Zach Nastasiuk, Morgan Klimchuk and Nick Ritchie scored in the second period as Canada pulled away from the Swedes.

Philippe Desrosiers made 28 saves for the shutout.

Despite the lopsided score, Canadian assistant coach Jody Hull said he didn't feel his team was in control until late in the second period. Canada took three straight minor penalties after McDavid's game-opening goal, allowing Sweden to build momentum.
