Mikael Granlund had two assists, Nino Niederreiter added an empty-netter and the Wild had the edge in every way, without being drawn into a single trip to the penalty box.
St. Louis’ Jake Allen stopped 21 shots, with the over-capacity crowd taunting him with chants of his last name throughout the game, but the Blues lost on the road in the playoffs for the ninth straight time.
Game 4 is in Minnesota on Wednesday.
