The St. Louis Blues had one of their best defensive showings in nearly two weeks last time out but that was against one of the league's weaker teams.
They would appear to have a greater challenge in Wednesday night's visit to Pittsburgh but the star-laden Penguins haven't proved consistent scorers for much of this season, especially in their past few games.
St. Louis' 2-1 win in Buffalo marked the first time it had given up fewer than two goals since back-to-back shutouts Nov. 7 and 10. The Blues (14-6-2) let their opponents score a combined 21 times in their previous six games.
