This was far from the dominant performance the skidding Bruins would like to see. The B’s are a long way from peak form, but to their credit, on a night when the Ottawa Senators didn’t allow them a whole lot of time or space, they kept grinding, made the third period their best of the night, and eked out a sorely needed 2-1 victory, their 11th consecutive win at Scotiabank Place. It came down to a seeing-eye shot from the right point by Dennis Seidenberg (No. 1), whose shot with 64 seconds left in the third found its way through a crowd of goalmouth traffic and slipped past Ottawa goalie Robin Lehner. The B’s snapped a three-game road losing streak, and won for the first time on the four-game trip that concludes in Toronto tomorrow night. A great showing? Hardly. But a needed two points. “I felt that we kind of turned it around in the third,” said B’s coach Claude Julien. “We haven’t been playing great hockey lately. We had to fight through it. We knew it wasn’t going to be pretty. But by battling through it, in the third we started getting back closer to the way we should play and the confidence came back.” Mostly kept to the outside by the hard-working Senators, and often out-skated, the B’s accomplished little offensively for most of two periods. That changed when Daniel Paille (No. 6) came in 2-on-1 with Tyler Seguin with 1:22 left in the second and snapped a wrister from the right circle off Lehner, tying the game at 1 after 40 minutes. Anton Khudobin saved the B’s many times in those 40 minutes, as he stopped 20-of-21 shots as Ottawa was clearly the better team. “I didn’t think we were as sharp,” said Julien. “Our will and desire were there, but when you’re not playing with a ton of confidence as far as execution, you make things hard for yourself. There were times we were bringing the puck wide, and we should have been shooting at the net. We’re trying to force plays again.”
