Peterka gave Buffalo a 1-0 lead on the power play at 6:37 of the first period. Jason Zucker collected a loose puck behind the net and sent a short pass to Peterka along the goal line by the right post, where he banked it off Ullmark’s left shoulder into the net.
Byram made it 2-0 when he snapped a one-timer from the right circle short side 17 seconds into the second period.
“I just saw that he had a little time and space, and thought I’d try to sneak back side,” Byram said. “He made an, obviously, unreal pass to me. That one felt good.”
Greig poked in his own rebound five-hole on Luukkonen to cut it to 2-1 at 7:31.
Byram extended it to 3-1 with a shot from the blue line that squeaked under Ullmark’s left arm 21 seconds into the third period.
Thompson scored 16 seconds later to make it 4-1. Alex Tuch's shot from the doorstep deflected in off the shoulder of Thompson, who had been pushed down in the crease and into Ullmark. The Senators challenged for goaltender interference, but the goal stood after a video review determined that Jake Sanderson pushed Thompson into Ullmark.
“I think ‘Tuchy’ was nice enough to pass it off my shoulder while I was laying on the ice. So, I owe him a dinner or something,” Thompson said. “Very unselfish of him. But I think it just starts with simplicity again. … You need to be going to the net; you need to be getting dirty. Usually when you do that, you get rewarded. I thought we, as a group, we had a commitment that we were going to the net tonight. Just continue that moving forward.”
