BOSTON -- The Penguins own the No. 1 seed in the Eastern Conference playoffs.
That clinched it with a 3-2 victory against Boston at TD Garden this afternoon.
The victory was the Penguins' sixth in a row and raised their record to 34-10.
They are 21-2 in their past 23 games, and will have nothing at stake during the final week of the regular season except a long shot chance to overtake Chicago for first place in the overall standings.
Jarome Iginla, one of general manager Ray Shero's key additions as the NHL trade deadline approached, broke a 1-1 tie with a power-play goal at 4:43 of the third period.
With Chris Kunitz screening Bruins goalie Tuukka Rask, Iginla drove a low slapshot into the net from about 10 feet inside the blue line.
Kris Letang made it 3-1 during another man-advantage at 8:29, beating Rask with a wrist shot from high in the left circle just 12 seconds after Bruins defenseman Matt Bartkowski, a Mt. Lebanon native, was penalized for high-sticking.
Letang's goal became the game-winner when Tyler Seguin of Boston scored with 2.6 seconds left in regulation.
Brad Marchand gave Boston its the only lead of the day with a nice individual effort during a power play at 10:18 of the opening period.
He carried the puck through the left circle and cut inside Letang before beating goalie Tomas Vokoun.
Jussi Jokinen pulled the Penguins even at 5:10 of the second, as he backhanded a puck by Rask from the right side of the crease for his tenth of the season and fourth in six games since joining the Penguins.
Matt Niskanen and Tanner Glass got assists. For Glass, it was his first of the season.
The Penguins are off until Monday, when they will visit Ottawa at 7:38 p.m.
