A scoreless tie evaporated with a flurry of goals during the second period of the 2012 Winter Classic.
Flyers forward Brayden Schenn knocked in a rebound to break a scoreless tie at 12:26 of the period.
Rangers goalie Henrik Lundqvist had been impenetrable before Schenn's tally, but the Flyers didn't take long to find another hole in Lundwvist's armor. At 14:21, Claude Giroux buried a backhanded shot into the top shelf.
The Rangers didn't quite hang their heads after Giroux's score, seizing back the momentum quickly with a Mike Rupp goal.
Lundqvist has 24 saves after two periods, while his counterpart Sergei Bobrovsky has 16.
