Perry made it 2-0 at 6:14 when he took a pass from Getzlaf while skating down the right side in the Blackhawks zone, cut toward the net and pulled up when Jordan Oesterle blocked his path. Perry then completed a 360-degree spin in front of the crease before shooting the puck past Forsberg.
"It's huge," Perry said of the early lead. "When you get an early power play, you want to move the puck around, everyone to feel it, and I thought we did a great job of that. ... Those are the things that show that you're ready to play a hockey game, and we were ready at the start."
Pettersson, playing in his eighth NHL game, shot through traffic and scored over Forsberg's right shoulder for a 3-0 lead at 2:09 of the second period.
"Joy. Just complete joy," Pettersson said of his first NHL goal. "It was a great game, fun time to score your first."
Anaheim made it 4-0 at 6:39 when Cogliano's pass from behind the net got through to Silfverberg in the slot, where he scored on a one-timer.
