The Penguins remained perfect in the month of March and extended their win streak to seven with the victory.
The Penguins (20-8-0) seemed to have cleaned up their defense, shutting the Leafs’ out in the first and third periods and allowing only one goal in the second period by Tyler Bozak.
Marc-Andre Fleury played an outstanding game in net, stopping 28 of the 29 shots that he faced.
Going into the third period, the Leafs (15-12-1) led 1-0, until Dupuis scored his 12th goal of the season with less than eight minutes left, tying the game at one off an incredible backhanded pass from Sidney Crosby. Chris Kunitz, who has attracted attention for his outstanding play as of late, added the other assist on the game-tying goal.
Five minutes later, Dupuis put the Pens ahead 2-1 with his second goal of the game, off another assist from Kunitz.
Craig Adams scored a shorthanded, empty net goal to put the game away with only ten seconds left on the clock.
The victory ties Pittsburgh with Montreal for first in the Eastern Conference. Both teams have 40 points.
The Penguins come home for their next game against the New York Rangers on Saturday, March 16, at 1:00 pm at Consol Energy Center.
