In what could be a first-round playoff matchup between the two Central Division rivals, the Wild doubled up the Blues 6-3 Saturday afternoon.
For the moment the Wild have a three-point lead on the first wild card spot in the Western Conference.
Minnesota has now beaten St. Louis twice in the span of seven days.
Justin Fontaine had a goal and two assists for his second career three-point game.
Zach Parise and Jonas Brodin scored 26-seconds apart in the second period to give the Wild a 4-0 lead and end Brian Elliott’s night early. Elliott allowed four goals on 16 shots.
“Five-10 minutes of the second period we weren’t very good. It’s pretty inexcusable at this time of the year,” said Jay Bouwmeester. “We know we’re playing desperate teams. They’re a team that’s right there and trying to stay in that playoff race.
“We’ve got to be a team that’s playing for first place.”
Chris Stewart, Thomas Vanek and Mikko Koivu had the other Wild goals.
Devan Dubnyk made 26 saves in his 31st consecutive start.
Vladimir Tarasenko and Jaden Schwartz each had a goal and an assist in the loss. With his two-point afternoon, Tarasenko now has 70 points on the season.
Paul Stastny also scored for St. Louis.
“There’s no excuses, we’re playing a team that’s desperate for their playoff lives and we’re trying to situate ourselves in the Central Division,” said David Backes. “You shouldn’t need anymore motivation at this time of the year.
“We need to be playing our brand of hockey every night, putting it all out there and if a team just plays better than us, we’ve got to tip our cap, but I don’t think we can say that tonight.”
Blues defenseman Carl Gunnarsson left the game with 13:50 remaining in the second period with an upper body injury and did not return.
Jake Allen made 10 saves in relief.
