"It was fun. It's fun winning," Barbashev said. "We've just got to keep winning."
The Blues last scored eight goals in an 8-3 win against the Edmonton Oilers on Nov. 21, 2017.
"Our team game is really solid right now," Schwartz said. "Obviously guys are feeling pretty good. I think you can tell in how aggressive we are. Everyone knows how the standings are and how tight it is. If you're losing a few, you're sitting on the outside looking in. I think we've done a good job of staying even-keeled and not getting too ahead of ourselves and approaching each game one at a time."
