Husso is 6-0-0 with a 1.11 goals-against average and .965 save percentage in seven games (six starts) in January.
"[Husso's] been huge for us, especially as of late," Blues forward Brandon Saad said. "I haven't seen a better goalie in the League lately. He's been great back there. I think when you have that, you're going to have confidence. Obviously, we don't want to give up too many chances, but when he can do that for us, it helps us transition."
Saad had two goals and an assist, and Brayden Schenn had a goal and an assist for the Blues (26-12-5), who are 14-1-1 in their past 16 home games.
St. Louis lost 7-1 at Calgary on Monday.
"The difference between the two games, I think we went to Calgary and thought it was going to be a little bit easier," Schenn said. "Not easy, we turned over the puck. We didn't have our skating legs. We chased it the whole night, it just kept on snowballing on us. And tonight, I think we had a good mindset to get the puck deep. We knew they were on a back-to-back, and just try and play heavy and hard, which we did tonight. And obviously, Husso was great again for us."
