BOSTON — Much like they did in the first period, the Bruins kept their foot on the gas pedal and as a result they were rewarded with another goal. Daniel Paille snapped one past Brian Boucher on a textbook 3-on-2 at 13:39 for his first career playoff goal (in his 10th career playoff game) and Nathan Horton added his third goal of the series — his fifth of the postseason — at 15:14 while Andrej Meszaros put the Flyers on the board with his second of the playoffs at 16:26.

The Bruins take a 4-1 lead to the locker room for the second intermission.

• Perhaps all the series previews should have focused on which Achilles heel would be the most haunting; the Flyers’ goaltending or the Bruins’ power play. The B’s had two power plays in the second period, and while they are now 0-for-30 with the man advantage this postseason, they had some more quality chances, particularly on the second period with Patrice Bergeron getting the best chances. But Sergei Bobrovsky, who replaced Boucher after he gave up the fourth goal, robbed Bergeron on a one-timer attempt on one shot, and Bergy hit the post on his second quality attempt.
• It might be too little too late to comeback in this contest, but the Flyers responded immediately after their sixth goalie change of the postseason with Meszaros’ tally. There’s still plenty of hockey left, but one has to wonder how Philly will respond in the remaining 20 minutes.
• Whatever happens tonight, Bobrovsky will most likely get the start in the Flyers’ net for Game 4.
• With his goal in the second period, Horton recorded a Gordie Howe hat trick. He dropped the gloves with Sean O’Donnell earlier in the period and earned a takedown after the two were whacking at each other in front of Boucher in the first few minutes.
• The Bruins have won 25 of 31 faceoffs, including 11 of 16 in the second period. Gregory Campbell and David Krejci are still perfect at the faceoff circle, while Bergeron lost his first draw to Jeff Carter.
