The Blues are third in the Central Division. They trail the Nashville Predators by four points for second place and are five points behind the first-place Winnipeg Jets. St. Louis is four points ahead of the Dallas Stars, who hold the first wild card.
Rookie goalie Jordan Binnington will start for the Blues. He is 12-2-0 with a 1.71 goals-against average .931 save percentage and four shutouts in his past 14 starts but has allowed seven goals his past two (1-1-0).
