Pittsburgh, PA (Sports Network) - Matt Niskanen and Dustin Jeffrey scored in the third period to lift the Pittsburgh Penguins to a 3-1 win over the Florida Panthers at CONSOL Energy Center.

With the teams even at 1-1, the Panthers failed to clear the zone after killing a penalty and Niskanen fired a slap shot from the blue line that beat AHL callup Jacob Markstrom at the 7:49 mark.

Jeffrey tapped in Matt Cooke's cross-ice pass at the left post with 4:45 to play.

Marc-Andre Fleury turned away 22 shots for the Penguins, who have beaten the Panthers eight straight times at home.

Pittsburgh's Evgeni Malkin missed a significant portion of the third after being driven into the end boards by Florida defenseman Erik Gudbranson. Malkin stayed down on the ice before skating to the bench on his power.

Markstrom finished with 37 saves for Florida, which has dropped six of seven.
