Bennett scored his second of the period at 19:34 to push the lead to 4-1.
Jonah Gadjovich made it 5-1 at 9:12 of the second period, jamming in a backdoor pass from Jesper Boqvist.
“You have to play all 60 minutes, and they are a good team who plays hard,” Gadjovich said. “But if we focus on our game, worry about ourselves, we’re going to walk away with a few wins."
McAvoy made it 5-2 at 12:32 of the second, scoring five-hole after Bobrovsky couldn't glove down John Beecher's initial shot.

Frederic made it 6-3 at 16:51 with a one-timer off a backhand pass from Justin Brazeau.
Pastrnak got the Bruins to within 6-4 with a power-play goal with 1:45 remaining. His intended pass from the left circle redirected five-hole off the skate of Panthers defenseman Dmitry Kulikov.
“The game was 4-1 after the first, so I am not too happy with that,” Korpisalo said. “There were a couple of weird bounces, but it was pretty hard to come back there. I just have to be better. It was 6-4. I’m not happy.”
