The Bruins inched closer to winning their second Stanley Cup championship in three seasons after defeating the Chicago Blackhawks, 2-0, in tonight’s Game 3 at the Garden. The B’s now have a 2-1 series lead. Game 4, again at home, is set for Wednesday night at 8 p.m. The Bruins did all their damage in the second period, getting goals from Daniel Paille and Patrice Bergeron. Paille got the B’s first goal, at 2:13. Tyler Seguin jump started things nearly getting one by Corey Crawford, but his rebound corralled to the corner. Chris Kelly fought to gain possession and was able to knock the puck near Paille. Then the Bruins’ left winger knocked the puck between Dave Bolland’s legs and proceeded to beat Crawford glove side. The Bruins had a couple close calls after their first goal, but added to their lead after consecutive penalties from the Blackhawks. At 12:00, Bolland got whistled for cross-checking Kelly. Chicago almost killed the penalty but with 11 seconds left, Niklas Hjalmarsson got sent to the box for tripping and the B’s capitalized. Almost as soon as their first power play ended, Bergeron beat Crawford off of a picture perfect, along the crease, at 14:05. Unlike Game 2, the Bruins came out of the gates firing tonight. They outshot Chicago, 6-1, in the first four minutes and controlled most of the early action. The Blackhawks got two power plays in the opening frame, but the B’s successfully killed both penalties. Down 2-0, the Blackhawks picked up their tempo, got two power plays and pulled their goalie in the third period, but Tuukka Rask (27 saves) held strong preserving this third shutout of the postseason. With 11.9 seconds left in the game, the Bruins and Blackhawks brawled. Zdeno Chara and Bryan Bickell went after each other. Then Brad Marchand and Andrew Shaw got into it.
