"Give the credit to our [defense]," Little said. "They were moving their feet and getting things through. That makes a huge difference when those are getting blocked. They did a good job tonight of not standing still and trying to get it through, but moving their feet and finding the lanes."
Marco Scandella, Johan Larsson and Scott Wilson scored for the Sabres, (10-22-9), who were playing the second game of a back-to-back after losing 6-2 against the Minnesota Wild on Thursday. Chad Johnson allowed four goals on 29 shots.
Buffalo, 1-3-2 in its past six games, went 0-for-5 on the power play.
"It's disappointing," said Sabres forward Ryan O'Reilly, who had four shots on goal. "I've got to find a way to put it past them. I had some great opportunities and it's just not good enough. I've got to contribute more, it's part of my job."
Byfuglien scored his first of the season on a point shot on the power play at 9:27 of the first period to make it 1-0.
Scandella, also without a goal this season, tied it 1-1 on a point shot at 11:40.
