Blues goalie Jake Allen was outstanding for the third consecutive game, making 40 saves and Jaden Schwartz had the go-ahead goal in the second period to give the Blues a 3-1 win over the Wild on Sunday for a 3-0 lead in their first-round playoff series.
Colton Parayko also scored for the Blues and Alexander Steen added an empty-netter for St. Louis, which will try to sweep the series Wednesday night in St. Louis.
Charlie Coyle scored for Minnesota, which got 28 saves from Devan Dubnyk. Dubnyk has allowed just two goals in each of the three games, stopping 92.3 percent of the shots he's faced, but the Wild have lost all three games.
Schwartz had a power-play goal at 15:19 of the second period to put the Blues one win away from the second round.
