UNIONDALE, N.Y. -- Chris Kunitz scored a power-play goal 8:44 into overtime Sunday afternoon to lift the Pittsburgh Penguins to a 5-4 victory over the New York Islanders in Game 3 of the Eastern Conference quarterfinals at Nassau Coliseum.
The Penguins took a 2-1 lead in the best-of-seven series. Game 4 is scheduled for Tuesday night at the Coliseum.
Pittsburgh trailed 2-0 less than six minutes into the game but scored four straight goals -- one apiece by Jarome Iginla, Kunitz, Pascal Dupuis and Paul Martin -- before the Islanders scored twice in the third period to send the wildly and frantically entertaining game to overtime in front of a boisterous sellout crowd of 16,170.
Marc-Andre Fleury made 32 saves for the Penguins, who are trying to win their first postseason series since 2010.
The Islanders, who were playing their first home playoff game since April 18, 2007, received early goals from Matt Moulson and Casey Cizikas. Kyle Okposo pulled the Islanders within a goal 5:31 into the third period and John Tavares tied it just after the midway point.
Goalie Evgeni Nabokov made 20 saves.
The Islanders have lost seven straight home playoff games dating to their last Nassau Coliseum win in 2002 and haven't won a playoff series since beating the Penguins in seven games in the 1993 Patrick Division finals.
The Islanders, energized by both the raucous noontime crowd and the momentum created by their come-from-behind 4-3 win on Friday night in Pittsburgh, dominated the opening minutes and scored just 1:43 into the game, when Lubomir Visnovsky fired a pass to Okposo just to the right of the Penguins' net. Okposo stabbed at the puck three times trying to poke it past Fleury before Moulson swooped in and nudged it into the net.
The Islanders extended the lead to 2-0 less than four minutes later when Michael Grabner's backward pass from behind the Penguins goal hit Cizikas in stride. Cizikas' shot eluded Fleury and Cizikas pounded the boards in celebration as the crowd roared its approval.
The Penguins tied it with two power-play goals in a span of just 19 seconds.
Seconds into a five-on-three opportunity, Iginla tipped Kris Letang's shot past Nabokov with 6:42 left in the period. Pittsburgh remained on the one-man advantage and Kunitz beat Nabokov from point-blank range.
Pittsburgh completed its comeback with exactly a minute left in the first period when a streaking Dupuis took a gorgeous pass from Sidney Crosby and snuck the puck past Nabokov.
The Penguins extended the lead to 4-2 with 2:50 left in the second when Martin capped a coast-to-coast rush by firing a shot past Nabokov that clanged off the top of the goal and into the net.
New York pulled within one on Okposo's short-handed goal early in the third. Frans Nielsen picked up a loose puck around center ice and passed to Okposo, who eluded Matt Niskanen and beat Fleury on the breakaway.
Tavares tied it with 9:12 left when he deked Mark Eaton and scored from the right faceoff circle.
