Reaching the intermission with a lead was a form of progress for the Bruins, who gave up two previous leads in this game after just 2:33 and 56 seconds, respectively.
Gregory Campbell made it 2-1 at 2:24 of the period after Torey Krug performed his second nifty between-the-skates move of the game just before shooting the puck on net, where Campbell backhanded the rebound past Henrik Lundqvist:
(Earlier in the game, Krug scored after receiving a pass through his legs and kicking it up to his stick.)
But just like in the first period, the Bruins coughed up the lead soon after Campbell's goal. Rick Nash scored on a rush, shooting with his forehand past Tuukka Rask for his first playoff goal as a Ranger.
The Bruins finally got a lead they could keep for a while, Boychuk scoring through a screen at 12:08 of the period.
That was enough for the Bruins to take a lead into the second intermission, though the Rangers again created some opportunities immediately after that goal, including Ryan Callahan and Ryan McDonagh combining to force a point-blank save from Rask.
The intensity of the series is picking up at the expected pace, with post-whistle scrums and some good hits. Nathan Horton made sure he appeared on the second-period highlight reels with a crunching hit on John Moore.
The Rangers outshot the Bruins 16-9 on the period and 27-21 overall through two periods. The Rangers failed to score on three power play opportunities, while the Bruins misfired on their lone opportunity.
