Andy McDonald scored twice to get St Louis off to a solid start before the Blues continued to display strong form on their travels by pulling away for a 5-2 victory over the Edmonton Oilers on Wednesday.
St Louis (40-17-7) kept their perfect start to a six-game road trip intact while earning their first four-game winning streak on their travels since 2009.
The triumph also tied the Blues with Detroit for the Central Division lead and moved them one point behind conference-leading Vancouver.
A dominant third period secured the result for St Louis as they held the lifeless Oilers (25-32-6) to just six shots with a majority of those coming in the final few minutes.
Edmonton appeared to seize the momentum when Corey Potter and Ryan Nugent-Hopkins reduced the deficit to a single goal but the Oilers were unable to sustain the effort.
