With the Penguins  handing the Bruins multiple opportunities with penalties, it was just a matter of time before Boston broke through.
Evgeni Malkin won the dubious distinction of being the man who committed the penalty (hooking – 2:15) that helped get the Bruins on the board. David Krejci  put the puck in the crease and banged on it to the point that Marc-Andre Fleury  fell flat on his stomach though not quite on top of the puck. Blake Wheeler  then snuck in and swept the puck out from under the goaltender for his 14th goal of the season that gave Boston a 1-0 lead at 3:12.
The Penguins came back in 5-0n-5 at 8:57 in a similar scenario to Wheeler’s goal. Pascal Dupuis swept around the goal only to be semi-stuffed by Tim Thomas  but the forward stayed on the puck and it trickled passed Thomas to tie the game at one apiece.
Michael Ryder  took a slashing penalty at 3:43 in the period but Boston was able to kill it off. In the middle of the period the teams played two-minutes of 4-on-4 as Ruslan Fedotenko and Mark Stuart  got in a tangle in the crease in front of Thomas that led to matching roughing penalties.
Shots in period (total):
Boston — 8 (11)
Pittsburgh — 11 (21)
