It took the Ottawa Senators nearly 20 minutes to realize they were in a hockey game. But thanks to a timely goal from Chris Neil, they shook off their first period stupor and handed the Boston Bruins a 4-2 loss on Friday night. Down 2-0 halfway through the first period, the Senators woke up when Chris Neil brought them to within one with 50 seconds to go in the first. After a scoreless second, they then flew past the Bruins with third-period goals from Jason Spezza, Jared Cowen, and Bobby Ryan. Loui Eriksson and Brad Marchand scored for the Bruins, who were playing the first of a three-game road trip. Craig Anderson, who last won on Oct. 23 in Detroit, faced 32 shots, while Tuukka Rask faced 31. The one sour note for the Senators was that Ryan left the game at 16:25 of the third after being elbowed in the head by defenceman Dennis Seidenberg. For most of the first period, the Senators looked as miserable as they did in Tuesday’s 5-0 loss to the Philadelphia. Fifteen minutes in, they were being outshot 11-3 and were behind 2-0, an entirely deserved result. On Boston’s first goal at 6:03, which was first given to Matt Barkowski before being credited to Eriksson, the Senators had four chances to get the puck out of the zone but turned it over four times. It was a comedy.
