Washington: Jake Allen made 32 saves with regular starter Brian Elliott back home resting as the St. Louis Blues beat the NHL-leading Washington Capitals 4-0 on Saturday night for their fourth consecutive shutout.

Kyle Brodziak, Colton Parayko, Vladimir Tarasenko and Patrik Berglund scored for the Blues, who have their sights on the Central Division title and the top seed in the Western Conference. With six games left, they’re tied with the Dallas Stars, who beat the Sharks 4-2 in San Jose.

“When your goalie’s hot, the confidence breathes through the rest o the team,” Brodziak said. “We’re feeling that right now.”

The Capitals would’ve clinched the Presidents’ Trophy with a point but now must wait until at least Monday.

Mattias Janmark returned to the lineup from injury and got his first career two-goal game while Antti Niemi made 34 saves against his former team to help Dallas win for the fourth time in five games. Niemi, traded to Dallas last offseason after five seasons in San Jose, got the win in his first start in two weeks.

“Really exciting game, exciting day,” Niemi said. “It’s been a while since the last game and also since the last win so it feels pretty good.”
