The Rangers (6-7-1) had three wins in their first 11 games before their current winning streak. Jimmy Vesey scored two goals, giving him five this season, and Neal Pionk scored his first. New York was 4-for-4 on the penalty kill, when Lundqvist made 14 of his saves.
"The PK really stepped up," Lundqvist said. "You could feel in the first period that they had a good power play, they were moving pucks so well side to side, creating chances, so we had to be on our toes. I think with each kill we got more and more confident."

Carter Hutton made 19 saves and Conor Sheary scored for the Sabres (7-6-2), who lost one day after defeating the Ottawa Senators 9-2. Buffalo has one win in its past five games (1-2-2).
"[Lundqvist] played a really good game, but I think we've got to find a way to get one," Sabres center Jack Eichel said. "We had a couple chances on the power play. I feel like I had a few chances. I hit the post in the first and missed a few of my shots in the second. It's frustrating. I thought we played pretty well, but it's tough when you've got nothing to show for it."
The Rangers took a 2-0 lead in the first minute of the second period on goals 19 seconds apart by Pionk and Vesey. It was the fifth time in franchise history, and first since March 24, 1982, that the Rangers scored twice in the opening minute of a period in a regular-season game.
