Couture extended the lead to 5-3 at 16:16 on a redirection in front, and Labanc made it 6-3 at 13:03 of the third period, scoring short side under the crossbar from the right circle on a power play.
"We're playing the right way now," Couture said. "Less cheating, less chances being taken in bad areas of the ice. Defensively we've played some very strong hockey and when we do that, it may be hard to realize, but it always leads to offense. You're always going to score more goals when you're defending well."
Hertl made it 7-3 at 18:27 from the slot.
"We just didn't play good defensively," Strome said. "Lots of errors. We left [Ward] out to dry. It's on us. He actually made some big saves for us and then we left him out there.
"When you're out there, it doesn't have much of an effect on if the goalie changes or whatever happens, we were just trying to continue to battle and that's what happens sometimes."
