"Keep the puck in their zone, no turnovers at the blue line, things like that," van Riemsdyk said. "We didn't want to give them anything easy on offense because we knew they wouldn't give us anything."
Zach Parise scored in a goal-mouth scramble with 0.6 seconds left in regulation and David Clarkson also scored for the Devils, who fell one win short of tying the NHL record of 10 road wins to start the season, set by the 2006-07 Buffalo Sabres.
"You never want to lose, but we knew that we weren't going to go 41-0 on the road," Parise said. "But 9-0 is pretty good, so we will just try to start it up again in Nashville [on Thursday]."
"We knew that they [Devils] were pretty hot coming in," Giroux said. "We stuck to our game plan by keeping it simple and shutting down their top forwards with great teamwork. We put a lot of pressure on them, made sure they didn't get a lot of room with the puck, and waited for our chances."
Powe put the Flyers ahead by shoveling in the puck from the slot at 7:11 of the first period. Arron Asham set the score up by intercepting a clearing attempt by Brodeur and passing to Giroux, who backhanded a pass to Powe.
Hartnell got credit for a power-play goal 44 seconds into the second period after Devils defenseman Mike Mottau attempted to intercept his centering pass and deflected the puck into the net.
Skating with 3 seconds left on a two-man advantage, Clarkson got the Devils on the board with 4:18 left in the second with a wrist shot from the crease.
Philadelphia made it 3-1 at 10:38 of the third period when van Riemsdyk picked up a loose puck in the slot and scored unassisted with a wrist shot.
"Brodeur's a tough goalie but I think I got a little lucky," van Riemsdyk said of his game-winning goal. "I sort of handcuffed him."
Asham left the game in the second period with an oblique strain on his left side and is expected to be out between 10 and 14 days.
