Giroux got the assist on the goal, moving him past Rick MacLeish for fourth in points Flyers history. Giroux has 699, trailing Bobby Clarke (1,210), Bill Barber (883) and Brian Propp (849).
"It's a great honor," Giroux said. "There's a lot of good players that played here, and to be able to be in that group, it's very special."
Giroux has eight points (three goals, five assists) during a three-game point streak, and 11 points (four goals, seven assists) in his past six.
"He seems to be on a mission, playing good hockey, batting hard, scoring some goals," Couturier said. "That's what you want from your captain. It pushes everyone to battle that much harder."
Couturier made it 3-0 at 4:18 of the third period when his shot from the left side was stopped by Crawford but bounced off Chicago defenseman Brandon Manning into the net. Manning played his first six NHL seasons with the Flyers and signed with the Blackhawks on July 1.
