Power plays gave the Toronto Maple Leafs ample opportunity to break open a tight game against the Pittsburgh Penguins.
When they couldn't take advantage, the Penguins cashed in to beat the Maple Leafs 2-1 Friday night at Air Canada Centre.
The Leafs went 0 for 6 on the power play after scoring three goals that way Wednesday night against the Boston Bruins.
Pascal Dupuis scored twice and Sidney Crosby reclaimed sole possession of the NHL lead in points with an assist for the Penguins (11-3-1), who responded from a 5-0 drubbing at the hands of the New York Rangers earlier in the week.
Cody Franson scored a third-period goal for the Leafs (9-6-2), who visit the Buffalo Sabres on Saturday night. Jonathan Bernier was solid in stopping 39 of the 41 shots he faced.
Penguins backup goaltender Thomas Greiss made 30 saves, including 13 in the third period.
