It took all of two seconds.
That would be the amount of time that Matt Cooke  was on the ice before Bruins forward Shawn Thornton  tracked him down and signaled for a fight. Cooke jumped the boards for his first shift at 1:56 and skated to across the ice towards his defensive zone corner. Thorton came straight at him and let him know that he was on his way and they dropped gloves and circled each other. Cooke got the first couple of punches before Thornton went in with as much vigor as has been seen from him this year, registering a couple hits to the head and then pulling his sweater over his head. When the referees pulled the enforcer off of Cooke he was still visibly upset and was restrained as Cooke made his way to the box for the five-minute fighting major. Thornton received the five-minute fighting major and a 10-minute misconduct for instigating the fight.
Then there was hockey to be played and when it comes to that, the Penguins  tend to fare better than the Bruins this season.
Pittsburgh scored the first goal of the game at 8:34 when Tyler Kennedy beat Tuukka Rask  on a wrist shot on a rush down the right wing. It was Kennedy’s 10th of the year and the Penguins had the early lead.
Like the last time the teams played (March 7 in Pittsburgh), Boston had a couple of power play opportunities to get on the board in the first period. The first came at 5:36 when the Penguins were called for too many men on the ice, served by Kennedy. The second came, much to the delight of the TD Garden crowd, against Cooke at 12:52 when he side-swiped defenseman Dennis Seidenberg  on the end boards behind Rask for a tripping penalty.
Just like March 7, Boston could do nothing with the man-advantage.
Outside of Thornton’s retribution and Kennedy’s goal, the play was even through much of the period but the Penguins will begin the second with a goal advantage.
