Alex Lyon made 29 saves for the Sabres, who were playing their season opener.
“The first 10 minutes, we were chasing the puck around an awful lot,” Buffalo coach Lindy Ruff said. “I thought once we got underway that second half, that second period, you know, we're in a one-goal game with five minutes left. Our passing wasn't very clean tonight. I think even on our power play, just some errant passes that we should connect [on], that we've been pretty good on. …
“Once we got going in the second period, we had our chances. We just didn't convert.”
Lafreniere gave the Rangers a 1-0 lead at 11:43 of the first period when he collected a loose puck at the right post and tucked it in behind Lyon.
“I think maybe I could have been a little bit more patient on it,” Lyon said. “Thought he made a good, strong play. He knew what he was doing to muscle his way into the net there, so credit to him.”
Carson Soucy made it 2-0 at 14:46 of the third period, beating Lyon blocker side from the left circle.
