After a 4-1 victory against the Columbus Blue Jackets on Saturday in which Schwartz, Schenn and Tarasenko were held without a point, it was their mission to come up clutch in a battle of the top two teams in the Western Conference.
"I thought we were better than last game," Schwartz said. "I thought we were moving a lot better, supporting each other better and just making strong plays with the puck. We weren't too happy with the last game. Our team played well. I know it was a big win against Columbus, but we knew we had better and we talked about it. We wanted to come out tonight and play a hard game against these guys."
The Blues are 6-0-1 in their past seven games and 5-0-0 at home this season.
Carl Gunnarsson and Vladimir Sobotka scored, and Jake Allen made 26 saves for St. Louis (10-2-1), which tied its record for wins in October.
"I think we've got a good thing going right now," Allen said. "We're relaxed, have confidence instilled in us right now. I think we're just finding ways to win games. It's fun to watch from my end. Guys are blocking shots; we're doing everything. It's the same stuff we comment on every game. We're just consistently doing it, and I think the more consistent you are the better chance you're going to win."
