PITTSBURGH (Reuters) - The Boston Bruins scored four goals in the final four minutes to steal a stunning 4-2 victory on Monday over a struggling Pittsburgh Penguins team that is still without injured captain Sidney Crosby.

The Bruins, who squandered a two-goal lead in the final minutes of their 3-2 loss against Montreal on Saturday, got goals from defenseman Zdeno Chara and left wing Brad Marchand 12 seconds apart to even the score and set up a wild finish.

Mark Recchi scored the winning goal on a backhand with 50 seconds remaining and Gregory Campbell sealed the comeback win with a long empty-net goal with eight seconds to play.

It was Boston's second straight comeback win over the Penguins after scoring five goals in the third period to climb out of a two-goal deficit and beat Pittsburgh 7-4 on November 10.

"Our last time here it was the same result - so we knew we could do it. We just had to believe in ourselves, and we did," Recchi told reporters.

"Our coach gave us a good talk (before the game). We have to build and make this process go well throughout the year."

Pittsburgh's Mike Rupp and Kris Letang scored in the second period while goaltender Marc-Andre Fleury made 28 saves and was in line for his second shutout of the season before being blitzed in the closing minutes.

Pittsburgh remained winless without Crosby, the NHL's leading scorer with 66 points, who missed his third straight game with a concussion.

Pittsburgh is one point behind the Philadelphia Flyers for the best record in the NHL's Eastern Conference.
