James Neal scored twice, the power play cashed in twice, and the Penguins chased Craig Anderson from the net for the second time this series to beat Ottawa, 7-3, at Scotiabank Place Wednesday night and take a commanding 3-1 series lead.

After giving up another shorthanded goal to open the game, the Penguins recovered -- and convincingly.

The Penguins trailed 2-1 after the first period, before building a 3-2 lead in the second.

Neal scored on the power play at 1:59 of the third period, finishing from the doorstep into an open net to make it 4-2, and it set off a goal explosion.

Pascal Dupuis scored shorthanded to make it 5-2 at 8:08, Sidney Crosby's backhander at 8:38 chased Anderson and made it 6-2, and Jarome Iginla scored on the power play at 9:53 to make it 7-2.

The series returns to Consol Energy Center Friday night for Game 5.

The Penguins built a 3-2 lead in the second period off a pair of goals 40 seconds apart by Chris Kunitz and Iginla.

Kunitz scored on a breakaway, beating Anderson through his legs at 1:08 of the second before Iginla finished a rebound off a shot by Kris Letang at 1:48.
