James van Riemsdyk scored, Claude Giroux had two assists, and Martin Jones made 27 saves for the Flyers (4-1-1), who have won their first two road games of the season. They won 5-3 at the Edmonton Oilers on Wednesday.
"In back-to-backs usually you have your legs going early and you've got kind of a carryover from the last game, especially [because] we had a big win last night," Couturier said. "It's more as the game goes on, you want to keep that same pace. It's not easy. The travel legs kind of get to you, but tonight we did a good job defensively and we had 'Jonesy' to save us a couple of times, so that was that was huge."
Philadelphia has won four of its past five and can sweep its three-game trip by defeating the Calgary Flames on Saturday.
"In the third (period) we found a way, even though on back-to-back nights and [being] late getting in here, we found a way to get the energy to roll the lines and get the two points, so really happy with what we've done these first two games on the road trip," Flyers coach Alain Vigneault said. "We're going to recover, we're going to rest up tomorrow and then we're going to get ready for Calgary."
