Henri Jokiharju scored, and Ukko-Pekka Luukkonen made 14 saves for the Sabres (5-6-0), who lost for the first time in three games.
“I just don’t think we played with enough urgency,” Buffalo captain Kyle Okposo said. “We know that team comes out, works, and we have to try to match their work ethic and play with purpose. And I just don’t think we started the game with purpose.”
Laughton gave Philadelphia a 1-0 lead at 1:03 of the first period, finishing a back-and-forth passing play with Brink from the left face-off circle.
Belpedio made it 2-0 just 28 seconds later after Morgan Frost’s shot hit the stick of Jokiharju and deflected to Belpedio in the right circle.
“[Felt] better than I expected, honestly,” said Belpedio, who made his NHL debut on April 7, 2018, with the Minnesota Wild and was playing his ninth NHL game. “It’s exciting. All the guys were happy for me, too. That makes it a little better. I’m sure my family and friends will have a couple of text messages on my phone for me, so I’m excited to get back and read those.”
