Senators 5, Bruins 2
Anthony Duclair scored two goals and added an assist as the Ottawa Senators defeated the visiting Boston Bruins 5-2 on Monday night.
Chris Tierney added a goal and two assists, Artem Anisimov and Jean-Gabriel Pageau also scored and Vladislav Namestnikov had two assists for the Senators, who won for just the second time in their past eight games. Goaltender Anders Nilsson made 38 saves.
Patrice Bergeron, making his return after missing the previous seven games with a lower-body injury, and Jake DeBrusk scored for the Atlantic Division-leading Bruins, who failed to win for the third consecutive game (0-2-1). Brad Marchand and David Pastrnak each had two assists and goalie Tuukka Rask stopped 23 of 26 shots.
Boston defensive miscues led to the first three Ottawa goals.
Anisimov opened the scoring just 1:35 into the game, taking a stretch pass from Dylan DeMelo at the Bruins' blue line and skating in on a breakaway. Anisimov put a backhander over Rask's left shoulder.
The Senators made it 2-0 at 15:44 of the period, after the Bruins turned over the puck behind their net. Tierney got the puck and passed to Duclair in the high slot, and his one-timer found the net.
Bergeron pulled Boston within 2-1 at 17:48 of the first, taking a cross-ice pass from Pastrnak and firing the puck from the right faceoff circle into a nearly empty net.
Tierney scored the lone goal of the second period at 1:21 after Rask turned the puck over behind the Bruins' net. Namestnikov and Duclair got assists.
Pageau scored an empty-net goal with the Bruins on the power play at 17:02 of the third to make it 4-1.
The Bruins got one back on DeBrusk's man-advantage goal off a scramble in front at 17:45, but Duclair capped the scoring with an empty-netter with one second remaining.
