ST. LOUIS -- Jaden Schwartz scored the go-ahead goal in the second period and Jake Allen made 40 saves to lead the St. Louis Blues to a 3-1 win over the Minnesota 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.

Schwartz had a power-play goal at 15:19 of the second period to put the Blues one win away from the second round. He scored with 2:27 left in the third period of Game 2 to give St. Louis the 2-1 win.
Allen was the star of the first two games. He stopped 74 of 76 shots for a .974 save percentage against a Wild team that ranked second in the NHL in scoring during the regular season.
The Blues scored just 3:25 into the first period when Parayko beat Dubnyk high with a shot from the high slot after a nice pass from Patrik Berglund. The goal was the third in 23 playoff games for Parayko, who scored four goals in 81 games this season.
