Blues 4, Panthers 0: Chris Stewart had a goal and assist while Brian Elliott made 31 saves for his 22nd career shutout as visiting St. Louis won its third straight.

Red-hot Alex Steen scored his league-leading 12th goal, tallying in his sixth consecutive game as the Blues extended Florida's winless streak to four (0-2-2). Derek Roy and defenseman Alex Pietrangelo also had goals for St. Louis, which has outscored the Panthers 11-0 in two matchups this season.

Making his second start of the season, Elliott turned aside 21 shots over the first two periods and watched his teammates break it open in the middle session with three goals in a span of under 5 1/2 minutes.

Roy scored the only goal of the first period, collecting a loose puck and cutting across the slot before sliding a backhander between the pads of Jacob Markstrom (19 saves). Stewart doubled the lead at 5:21 of the second with a snap shot from a near-impossible angle at the bottom of the left faceoff circle.

Pietrangelo scored for the third straight game, sneaking behind the defense to chip a puck past Markstrom before Steen capped the scoring by converting a rebound at 10:42.
