"I just try to play aggressive, be on attack, all while being smart," Nelson said. "Playing with Anders and [Bailey], they're going to get you the puck and make good plays. A couple of times I was able to see that and get some good looks."
Lehtera scored to make it 3-1 at 6:28 of the second.
Pelech's goal at 8:17 of the third period to make it 4-1, Nelson scored at 8:58 to make it 5-1, and Lee's power-play goal at 11:09 pushed the lead to 6-1.
The Flyers have lost four of six home games, (2-4-0) and start a four-game road trip at the Anaheim Ducks on Tuesday.
Last season they ended a 10-game losing streak with a three-game sweep through Western Canada. They're hoping for similar luck this season.
"When you go on the road for a long time with your teammates, you get a little closer," Giroux said. "That's what we need right now, we need to get closer as a team. We need to go out there and play for each other. This road trip is going to be very important for the season."
