Conor Sheary scored on Johansson's cross-crease backhand feed to make it 2-0 at 1:35 of the second.
"We feed off each other," Sheary said. "I think he likes to play with a lot of speed, as do I. We play a lot of give-and-goes, and with [Jimmy Vesey] working out there too, I think our line just has some good chemistry right now."
Reinhart extended it to 3-0 at 5:42 with a one-timer from the top of the left face-off circle on the power play, chasing Bobrovsky from the net.
"At that stage of the game, you know, I think they didn't have much time in there, he probably didn't have enough shots to get into the game. And I didn't like the third one," Quenneville said.
Matheson scored with a wrist shot from the top of the left circle to cut it to 3-1 at 12:40 of the third period.
With the extra attacker on, Dadonov narrowed it to 3-2 at 18:50 after he pounced on a loose puck in the crease.
"It's kind of one of those games where you look back and you feel like you played a decent game. But if a couple of those shots had gone in, we'd be feeling much different," Matheson said. "At the end of the day, they didn't, so we need to find ways to be better and to bury those chances when we get them."
