Penguins 4, Islanders 3 (OT): Defenseman Brooks Orpik scored 7:49 into overtime as visiting Pittsburgh put away pesky eighth-seeded New York to win its Eastern Conference first-round series in six games.

Evgeni Malkin, who had two assists, and Tyler Kennedy exchanged passes before the latter fed Orpik at the point. The defensive-minded blue-liner blasted a shot which sailed over the right shoulder of Evgeni Nabokov (17 saves) and under the crossbar for his first career playoff goal. The tally was Orpik's first since Nov. 21, 2011 - ironically in a 5-0 win over the Islanders.

Defenseman Paul Martin scored to forge a 3-3 tie with 5:16 remaining in the third period as his shot from the point deflected off the stick of New York's Frans Nielsen and past Nabokov.

Pascal Dupuis netted his team-leading fifth goal of the series and Jarome Iginla added his 30th career postseason tally. Tomas Vokoun turned aside 35 shots for the top-seeded Penguins, who will face seventh-seeded Ottawa in the second round. Pittsburgh won all three regular-season meetings with the Senators.

Michael Grabner collected a goal and an assist while Hart Trophy finalist John Tavares and Colin McDonald also tallied. Keith Aucoin set up a pair of goals for the Islanders, who have lost their last six postseason overtime games dating back to 1993.
