Goaltender Thomas Vokoun shut out the New York Islanders, 4-0, tonight at Consol Energy Center, giving the Penguins a 3-2 lead in the first-round playoff series.

Following a scoreless first period -- just the second period of the series without a goal, the other being the third period of Game 1 -- the Penguins broke things open with three goals in the second period.

Tyler Kennedy, who had been a healthy scratch in the first four games of the series, gave the Penguins a 1-0 lead at 7:25 on a breakaway. Kris Letang set up Kennedy just outside the blue line with a pass from his own hash marks.

The Penguins pushed their lead to 2-0 at 8:47 when Douglas Murray's shot from the left point bounced off New York goaltender Evgeni Nabokov, up and over him into the net.

Sidney Crosby made it 3-0 with a strong individual effort. He took a feed from Jarome Iginla, broke over the blue line, split the Islanders' Lubomir Visnovsky and Thomas Hickey, took a bump by Hickey without losing the puck, and scored from near the right hash marks, beating Nabokov on the far side at 14:00 of the second.
