Vladimir Tarasenko scored on a pair of impressive wrist shots, Brian Elliott made 39 saves and the St. Louis Blues beat the Chicago Blackhawks 4-3 on Tuesday night to open a commanding 3-1 lead in their first-round playoff series.

Jaden Schwartz scored a tiebreaking power-play goal in the third period for the second straight game as St. Louis moved to the brink of its first appearance in the Western Conference semifinals since 2012. The Blues were eliminated in the opening round in each of the past three years.

Game 5 is Thursday night in St. Louis.

Duncan Keith had two goals for Chicago, which dropped consecutive home playoff games for the first time since 2012.

Andrew Shaw had a goal and two assists, and Corey Crawford finished with 16 saves after getting into a fight with Blues rookie Robby Fabbri during a wild second period.
