Anders Nilsson made 38 saves.

Patrice Bergeron and Jake DeBrusk scored for the Bruins, who were playing the first of four road games. Tuukka Rask made 23 saves in his first loss in regulation since Nov. 8.

Leading 3-1 to start the third, the Senators did a good job of containing the Bruins, who were pressing to close the gap.

With the Bruins on the power play, Rask was pulled for a 6-on-4 advantage, but Pageau was able to pick off a pass and break in for an empty-net goal to seal the win with just under three minutes remaining.

DeBrusk scored a power-play goal 43 seconds later, during a scramble in front of Nilsson. That was as close as the Bruins got as Duclair added another empty-net goal.

Ottawa made it a two-goal game early in the second as Vladislav Namestnikov intercepted a pass from Rask behind the net and found Tierney, who scored his fourth of the season.

The Senators held a 2-1 lead after the first 20 minutes.

Ottawa opened the scoring 1:35 into the game when Dylan DeMelo made a pass to Anisimov, who broke through the defense and sent a backhander over Rask’s shoulder.

Duclair scored his 14th of the season and made it 2-0 as he took a pass from Tierney in the slot and beat Rask on the glove side.

The Bruins cut the lead in half as Bergeron, who was making his return after missing the last seven games with a lower-body injury, took a cross-ice pass from David Pastrnak and scored into an open net.

NOTES: The Senators will be without goalie Craig Anderson for at least a week. He tweaked his knee Dec. 7.
