Sanderson made it 2-0 at 8:26 with a wrist shot from the slot.
“There are a lot of momentum shifts in games, so we’ve got to be ready for that,” Canadiens forward Sean Monahan said. “To give up two early, it’s obviously never a good thing, but we’ve got to be able to bounce back from that.”
Pinto pushed it to 3-0 during 4-on-4 play at 6:22 of the second period. He took a stretch pass off the left-side boards from Claude Giroux from his own goal line and beat Allen on a breakaway.
“I saw he had the defense beat, and I just tried to bank it for him to get it,” Giroux said. “He’s not going to miss a lot of those, so I was extremely happy for him.”
Kovacevic’s shot from the point through traffic at 12:31 of the third period cut it to 3-1.
“I just thought we made a really good push in the third period, but how can we find ways to create more of that energy?” Canadiens forward Josh Anderson said. “I thought we played fine and we had our chances. Obviously, we’ve got to capitalize on them.”
Joseph scored an empty-net goal at 17:33 for the 4-1 final.
“The first two periods, I think we were solid in what we wanted to do, and we were consistent and just played a mature game,” Giroux said. “And in the third period they came at us pretty hard, but at the end of the day we found a way to get the win.”
NOTES: The Senators have eight straight wins against the Canadiens, their longest active streak against an opponent. … Giroux’s assist was his 699th; he is one shy of becoming the sixth active player to reach 700. … Montreal forward Tanner Pearson had one shot in 11:26 of ice time in his first game since Dec. 9 after missing 19 games with an upper-body injury.
