Defenseman Brooks Orpik scored 7:49 into overtime to send the Pittsburgh Penguins to the second round of the NHL playoffs with a 4-3 victory over the New York Islanders.
Orpik, who posted his first career playoff goal, fired a long drive from just inside the blue line that beat Islanders' goaltender Evgeni Nabokov to give the Penguins a 4-2 series victory.
Penguins' forward Tyler Kennedy set up the winner by passing back to Orpik for a one-timer.
Paul Martin tied the game late in third period for the Penguins, who will square off against the high-flying Ottawa Senators in the quarter-finals of the NHL's postseason.
Jarome Iginla and Pascal Dupuis also scored to support an impressive 35-save performance from goaltender Tomas Vokoun.
John Tavares, Colin McDonald and Michael Grabner scored for the Islanders, who were aiming to take Pittsburgh to a game seven of series on Sunday.
Nabokov finished with 17 saves in the season-ending loss.
