PHILADELPHIA -- Simon Gagne is proving he can be a premier goal scorer in the new NHL.
"He's built a great foundation of two-way hockey," Flyers coach Ken Hitchcock said of Gagne. "He's a heavy player. He scores greedy goals. He scores three goals tonight, but the three plays he makes in the third period tonight in our (defensive) zone were unbelievable."
Gagne leads the NHL with 15 goals, and has scored five goals in his last three games. Forsberg leads the league with 21 assists. The Flyers' top line of Gagne, Forsberg and Mike Knuble accounted for three of the Flyers' four goals in the win.
"Simon is kind of everywhere right now," Forsberg said. "He's putting the puck in the net, and he's making me and Mike (Knuble) just enjoy the ride."
Forsberg had assisted on each of Gagne's goals this season before his linemate's second goal.
"It's been a great time playing with Peter and Mike on the same line," Gagne said. "We got a couple again tonight. I feel pretty good right now."
Gagne's first hat trick came in March 2002 in New York against the Rangers, in a game the Flyers lost. Since then, Gagne believes he's developed into a more complete player.
"I'm having a great time right now," he said. "The last two years have been a little tough, but this year, I'm enjoying to play the game again. I'm excited when I come to practice and every game. I enjoy every game and every shift."
Robert Esche made 28 saves and won his fourth straight game for the Flyers.
Atlanta outshot Philadelphia 26-11 in the last two periods, including 13-3 in the third.
Philadelphia had a two-man advantage when Gagne opened the scoring 3:46 in, redirecting Forsberg's pass and beating Dunham to the stick side.
Forsberg added to the lead with less than 2 minutes remaining in the period, scoring his fourth goal on his own rebound after a pass from Gagne. Hossa scored Atlanta's first goal 8 minutes into the second on a power play, beating Esche to the stick side.
Hossa, who has six power-play goals this season, has recorded a point in 10 of 14 games.
Esche stopped Marc Savard on a breakaway seconds later, preserving Philadelphia's lead. Gagne scored his second goal less than 2 minutes into the third period with Philadelphia on another two-man advantage. He beat Dunham with a shot from the slot.
"They're good players," Dunham said of Gagne and Forsberg. "You give players like that 5-on-3 chances, they're going to take advantage of it."
After Peter Bondra cut the lead to 3-2, Gagne scored his third goal with less than 5 minutes left, beating Dunham while lying on the ice. Serge Aubin made it a 4-3 game 52 seconds later, beating Esche on the short side.
