The celebration came two nights later than expected. The Penguins forced the series back to Pennsylvania by tying Game 5 with 34.3 seconds left in regulation and winning it shortly before 1 a.m. in Detroit on Petr Sykora's power-play goal in triple overtime.
Undeterred, the Red Wings hit the road and wrapped up their fourth straight series on the road in these playoffs. Detroit is third in NHL history with 11 Stanley Cup titles, trailing fellow Original Six clubs Montreal and Toronto.
Just like in Game 5, things got a little dicey for the Red Wings, who allowed Sergei Gonchar's power-play goal with 1:27 remaining that got the Penguins to 3-2. Pittsburgh had already pulled Game 5 hero Marc-Andre Fleury to create a 6-on-4 skating edge.
With the final seconds ticking down, Penguins captain Sidney Crosby put a backhander on goal that Marian Hossa just missed with a tip at the right post.
It set off a pile-on celebration behind the Detroit goal for the Red Wings, as the disappointed fans in Mellon Arena saluted their club once more with a chant of "Let's Go Pens!"
In the best night for Swedish hockey since the national squad won the gold medal at the 2006 Turin Olympics, defenseman Nicklas Lidstrom became the first European captain of a Stanley Cup champion, and Henrik Zetterberg, who had a goal and assist in the Cup clincher, won the Conn Smythe Trophy as playoff MVP.
His goal 7:36 into the third period pushed the Red Wings' lead to 3-1. He tied teammate and countryman Johan Franzen for the playoff lead with 13 goals, and matched Crosby for the postseason scoring crown with 27 points.
Lidstrom is one of five players to be the Red Wings for their four most recent titles (1997, 1998, 2002, 2008).
Crosby came close in his third NHL season to adding a Stanley Cup title to his resume that already includes a scoring title and a league MVP award.
Brian Rafalski gave Detroit a 1-0 lead in the first period and Valterri Filppula doubled it in the second. Chris Osgood made 20 saves and improved to 14-4 in the playoffs after taking over for No. 1 goalie Dominik Hasek in the first round of the playoffs against Nashville. Osgood allowed only 30 goals in 19 games.
Detroit earned its final two victories of the championship series in Pittsburgh, where the Penguins won their first nine postseason games. Until the Red Wings came to town, the Penguins hadn't lost at home since February.
