The Penguins started the day by unveiling a statue honouring Hall of Famer Mario Lemieux outside Consol Energy Center.

Phil Kessel and Carl Gunnarsson scored for Toronto. The Maple Leafs let an early two-goal lead slip away while falling to 1-2 since Randy Carlyle took over as coach following Ron Wilson's firing.
