Larkin put Detroit up 1-0 at 3:40 of the first period, collecting a loose puck in the slot and shooting past Comrie on the glove side.
Fabbri knocked a bouncing puck over Comrie from in front to make it 2-0 at 8:25. He has nine points (six goals, three assists) in his past seven games.
“I think he’s just doing some quality things around the whole ice to get himself in those positions and obviously, he’s cashing in right now,” Lalonde said.
Moritz Seider extended the lead to 3-0 with a one-timer from the point on the power play at 5:43 of the second period.
Rasmussen got between the Buffalo defensemen and scored five-hole on a breakaway to push it to 4-0 at 13:55.
Rasmus Dahlin’s point shot on the power play cut it to 4-1 at 18:57.
Casey Mittelstadt narrowed it to 4-2 at 8:20, scoring short side from the bottom of the left circle off a cross-ice pass from Skinner, and Skinner took a puck off the boards and deked to his backhand on the power play to pull the Sabres to within 4-3 at 11:37.
“Clock moving and their back was to the wall, and their mentality changed, obviously,” Buffalo coach Don Granato said. “The puck pressure, systematically, way better at pressuring pucks. Way more aggressive and assertive, handing off the pressure, supporting the next guy to pressure and more confidence with the puck. … Listen, you’re going to be vulnerable when you’re aggressive, you’re going to give stuff up. You’ve got to be comfortable with that. And when you’re not as successful as you want to be, you start fearing a mistake and you’re making the same mistake not being aggressive, and that’s the worst. That was the early part of the game.”
