UNIONDALE, N.Y. – Brooks Orpik scored 7:49 into overtime, and the Pittsburgh Penguins overcame three one-goal deficits in Game 6 to eliminate the New York Islanders with a 4-3 victory Saturday night.

Orpik, a defenseman, took a shot from the left point that might have clipped Islanders forward Brad Boyes on its way past goalie Evgeni Nabokov.

The Penguins advanced to face the Ottawa Senators in the second round of the playoffs despite being outshot 38-21 in the decisive win.

The Islanders were just 5:16 away from sending the series back to Pittsburgh for one more game when another defenseman, Paul Martin, got the Penguins even for the third time.

Evgeni Malkin assisted on the tying and winning goals. On Martin’s goal, Malkin curled behind the New York net with the puck and sent a hard pass high in the zone to Martin, who ripped a drive through traffic in front.

Michael Grabner had given the Islanders a 3-2 edge 2:21 into the third.

He scored his second career NHL postseason goal off a feed from Keith Aucoin to give the Islanders their third lead against the top-seeded Penguins. The goal left Pittsburgh netminder Tomas Vokoun sprawled out on his stomach.

The teams had alternated wins since the Penguins took the opener 5-0 at home.

John Tavares, Colin McDonald and Grabner gave New York leads in each period. Aucoin had two assists and Nabokov made 17 saves.

Jarome Iginla tied it in the first, and Pascal Dupuis made it 2-2 in the second for Pittsburgh, which got 35 saves from Vokoun.

Despite being outplayed for much of the game — as evident by the shot disparity of 28-13 through two periods — the Penguins entered the third in a 2-2 tie.

Pittsburgh overcame a pair of New York power plays in the second — including one for too many men on the ice that had Coach Dan Bylsma irate on the bench — and got even again when Dupuis scored his fifth of the series with 9:01 remaining.

Joe Vitale raced along the right wing boards and flung the puck in front to Dupuis, who redirected it past Nabokov.

Pittsburgh nearly took its first lead of the night in the final minute of the second when Crosby eluded Frans Nielsen behind the net and found Chris Kunitz at the right post for a one-timer that Nabokov blocked.

The Islanders showed no signs of nervousness or that the moment was too big for them despite the lack of playoff experience throughout the roster.

New York forced the Penguins into an early icing violation that caused Bylsma to burn his lone timeout in order to rest the tired players forced to stay on the ice.

The Islanders kept the pressure on and spent a large chunk of time in the Pittsburgh end, and it led to an early goal.

Josh Bailey dug the puck out of the right corner and fed a perfect backhanded pass out to Tavares, who was left alone as he skated into the slot. Tavares snapped off a crisp wrist shot from the hashmarks that beat Vokoun at 5:36.

NOTES

RANGERS-CAPITALS: Forgive New York’s other team if it has a quiet confidence heading into a must-win game against the Washington Capitals.

The Rangers will host Game 6 on Sunday and must win to force a deciding contest in the nation’s capital Monday.

But through five games, the home team has come out on top in each.

“I think the electricity in the building can sometimes get you through moments where maybe you’re sluggish,” Capitals Coach Adam Oates said. 

RED WINGS-DUCKS: Three periods haven’t been enough for Anaheim and Detroit to decide three straight games and four overall in their first-round series.

No one will be surprised if Game 7 on Sunday night in Anaheim extends beyond regulation to tie an NHL record.
