Pavol Demitra scored twice, including an empty-netter, to help the Wild win for the fifth time in six road games. Brian Rolston and Petteri Nummelin each had two assists for Minnesota, which before the current road success had a franchise-record 11-game winless slump.
Eric Brewer and Jay McClement scored for the Blues, who had been 7-1-1 in their previous nine and entered the game eight points behind Minnesota for the final Western Conference playoff spot. St. Louis has lost its last two at home and is 10-13-1 at the Scottrade Center, next-to-worst in the NHL.
The Blues have lost two straight in regulation for the first time since they dropped their first two under new coach Andy Murray Dec. 12-13. St. Louis is 13-6-4 overall under Murray.
