"We were ready from the start with our power play," Perry said. "That was a big part of our game. We moved the puck pretty well, got some traffic and got some rebound goals. That's what you have to do on the power play."
Another power play put the Ducks in front 3-1 with 46.7 second left in the period, as Rickard Rakell shuttled the puck across the crease, and Vermette threw it off Senators defenseman Cody Ceci and over the stripe.
"We know the importance of the power play, and we pointed it out before the game," Vermette said. "Special teams make a difference in the game. Usually you don't get too many chances, so you want to make sure you capitalize on those. Those goals came in handy for us."
The two-goal lead became three courtesy of Nick Ritchie's seventh of the season, scoring on the 3-on-2 rush off a Vermette feed.
