When the Bruins hit the ice against the Ottawa Senators at home on Tuesday they’ll be looking to repeat at least part of their Sunday night triumph over the Buffalo Sabres. No, they’re not looking to go scoreless through the first two periods of the game. The Bruins are looking to get on the board first and play with the lead as they finally did in the third period of Sunday night’s 2-0 win over the Sabres. That game snapped four straight games in which the opposition scored first and the Bruins eventually fell behind by a 2-0 score in each of those games. For a hockey club that’s put up some pretty spotty play in the third periods of games recently as well, that’s a troubling trend where sleepy first periods can't be tolerated. The Bruins were happy to reverse it on Sunday and will be looking for more of the same this week. “It was a tough game. It was probably a really boring game for most of the game, but we found a way to score that first one. From there we were able to control the game,” said Zdeno Chara. “We were getting closer and closer to getting the second one, and then we just wanted to finish the game strong.” The Bruins haven't scored a goal in the first period of seven straight games dating back to the St. Patrick’s Day loss to the Pittsburgh Penguins, and are 3-4 in that stretch of games. It’s the longest they’ve gone without cobbling together some offense in the first period since going through a nine-game stretch in October 2001, while setting a standard for first period futility.
