Game 2 is Friday at Pittsburgh.

ANAHEIM, Calif. (AP) - Mike Fisher had two goals and an assist, Pekka Rinne made 27 saves, and Nashville clamped down defensively on high-flying Anaheim in a playoff series opening victory.

VANCOUVER, British Columbia (AP) - Chris Higgins and Jannik Hansen scored in the first period, Roberto Luongo made 32 saves, and Vancouver beat Chicago in the playoff opener.
Corey Crawford made 31 saves in his first playoff start as Chicago opened its defense of the Stanley Cup with a loss.
The Canucks are the top seed in the Western Conference and the Presidents' Trophy winners, but the Blackhawks aren't the average No. 8 seed. Chicago knocked the Canucks out of the playoffs the previous two seasons and was formidable again in Game 1.

Vancouver will host Game 2 of the series on Friday.
