It's the 11th time in NHL history a team has had four straight shutouts. St. Louis is the first since the Phoenix Coyotes had five straight Dec. 31, 2003, through Jan. 9, 2004, to set a modern NHL record.
The Blues have not allowed a goal in 240:18, the longest shutout streak in their history.
"It's huge, and especially on a couple of shutouts, we've limited to the teens in the shots," Allen said. "That's an aspect from mine and Brian's standpoint where that's a credit to all the 20 guys in front of us; that's not just us. It goes to show we're on the upswing right now and we're playing well heading into the [Stanley Cup Playoffs]. We're right where we want to be."
It was Allen's sixth shutout of the season and the 11th of his NHL career.
"When we trust him to make that first save, he trusts us to get that rebound and get it out, and we're good at kind of trying to keep that second or third opportunity away from him, and that's what we did," Blues forward Paul Stastny said.
