(Photo credit: Sharon Bradley) Patrice Bergeron scored the game-winning goal in over time tonight to lift the B’s (13-2-2) over the Ottawa Senators to end their five game winning streak.

Through 20 minutes of play the Bruins lead the Maple Leafs 1-0 thanks to a late goal by Patrice Bergeron. Bergeron poked home a loose puck after great hustle by Tyler Seguin who got the puck to the net. Brad Marchand picked up the secondary assist on Bergeron’s 6^th goal of the year.

After a questionable hit along the boards to Jay Pandolfo, Adam McQuaid took to the aid of his teammate and dropped the mitts with Mark Fraser in what was a sprited bout between two big boys.

Here are my three observations from the first period.

1. Bruins blue-liners solid through 20.

One of the key issues in Tuesday’s loss to the Capitals was the play of the Bruins defensemen, but through 20 minutes of play here tonight the Bruins have been great in their own end. The only real big chance the Leafs had in the opening frame came on a 5-3 advantage. From an offensive standpoint the Bruins D had some great puck movement and looked very comfortable with the puck.

2. Bruins new third-line survives first period

In case you missed it this morning, Chris Bourque was placed on waivers and the B’s inserted Jay Pandolfo into Bourque’s spot on the third line with Chris Kelly and Rich Peverley. The trio looked very well together and just missed out on scoring late in the period as they had a few solid chances.

3. Business as usual with Bruins penalty kill

The penalty kill was huge once again for the Bruins as they killed off two Leafs power plays including a 5-3. The Black and Gold held the Leafs to just two shots on net on the man advantage.
