BOSTON _ Boston scored four unanswered goals to wipe out a 2-0 deficit en route to a 4-3 victory Thursday night against the Penguins at TD Garden.
The Penguins reached the NHL All-Star break with a record of 30-13-5, leaving them third in the Metropolitan Division. They trail first-place Washington by seven points.
Boston nearly took a 1-0 lead in the opening minute of the first period, but David Krejci's uncontested shot from the slot caromed off the crossbar.
That obviously was a lucky break for the Penguins, but not their biggest one of those 20 minutes.
That came at 7:37, when defenseman Justin Schultz slid a pass toward the front of the net from low in the right circle.
It went directly to Bruins defenseman Brandon Carlo, who inadvertently swatted it into the Bruins' net to give the Penguins a 1-0 advantage.
A great pass, not good fortune, was responsible for the Penguins' second goal.
Phil Kessel scored it at 11:26, when he took a cross-ice feed from Sidney Crosby and drove it into an open net from the left dot for his 15th. Schultz got the second assist.
The Penguins had a chance to blow the game open when they were awarded another man-advantage 36 seconds into the second period, but it proved to be the trigger for a Boston surge.
Brad Marchand, who earlier in the day had dodged a suspension but been fined $10,000 by the league for a "dangerous trip," cut the Penguins' advantage in half with a short-handed goal at 1:38.
He chased down a pass from teammate Patrice Bergeron and beat Penguins goalie Matt Murray from inside the left circle.
Marchand then tied the game at 6:27, when he threw a shot past Murray from the inner edge of the right circle.
Boston went in front, 3-2, during a four-on-four at 10:25, as Riley Nash deflected at Torey Krug shot by Murray.
The second intermission didn't disrupt the Bruins' momentum, and Bergeron got what proved to be the game-winner with a power-play goal 51 seconds into the third period, sticking a shot under the crossbar from the front lip of the crease.
Patric Hornqvist finally stopped the Bruins' run of goals at 10:35, when he got a feed from Chris Kunitz and beat Boston goalie Tuukka Rask from the edge of the crease for his 12th, but the Penguins couldn't get the goal that would have forced overtime.
The Penguins will not play again until Nashville visits PPG Paints Arena on Tuesday.
