The Rangers, who hadn't scored two goals in regulation in their previous four games, scored twice in the firstperiod, but the Devils tied it on goals by slumping players.
Morrow and Marleau scored first-period goals to put Canada in charge and Getzlaf's third in the second period seemed to have made it plain sailing for the home side.
Down 2-1 after the firstperiod, the Penguins scored twice in a 40-second span early in the second and added four goals in the first 10 minutes in the third.
