Tim Thomas made 43 saves, and Gregory Campbell, Benoit Pouliot and Tyler Seguin scored goals for Boston, which extended its point streak to 15 games with a 3-1 win against the Eastern Conference-leading Pittsburgh Penguins on Monday night in Pittsburgh.
Seven of Thomas' saves came when the Bruins were down two men, holding the Penguins scoreless on the power play, despite 3:10 of 5-on-3 time in the second period.
Campbell scored at 2:57 of the second as he scooped up his own rebound off of Marc-Andre Fleury, who left a lot of rebounds in front of him during the course of a game in which he made 24 saves. After Brad Marchand slew-footed Matt Niskanen 20 seconds later, the two dropped gloves and squared off. Zdeno Chara went just 50 seconds later for interference.
The Bruins killed off the ensuing 5-on-3, and a minute after Chara got back on the ice, Rich Peverley found Pouliot on a 3-on-2 rush and the former Montreal Canadien beat Fleury with a wrist shot to give the Bruins a 2-0 lead.
The third period featured more than a few fireworks, but only one of them involved a goal, which was scored by Tyler Seguin on the power play.
Sidney Crosby and Kris Letang collided at center ice, and Crosby went off, barely able to put weight on his right leg. Later in the period, a clean hit by Daniel Paille cut Evgeni Malkin's face and Joe Vitale went high on Tim Thomas.
Campbell took exception to the hit and the two threw down, landing a handful of punches before heading to the box.
The Bruins hightailed it after the game to Winnipeg, where they'll face the Jets Tuesday night.
