"Sometimes you can get on a roll like that," Elliott said. "Our team is playing so well right now. Guys are getting in shot lanes and blocking shots. Nothing really got through. All the guys are in it together. All the guys are buying into it and wanting to win every game."
Elliott, who signed a $600,000 free-agent contract this summer to be the Blues' backup, has won all four of his starts. He also has been in net for St. Louis' last three wins.
"He's played great for us," said Steen. "We are winning hockey games. I thought tonight there was a couple of times when Vancouver pushed us down in our own end. He just kind of calmed things down."
The shutout was Elliott's first of the season and 10th of his career.
"You can't get too satisfied," he said. "You sit back a little bit and it comes to bite you.
"I try to keep an even keel. Every time I get in there I just keep doing the same thing."
The Blues improved their record to 5-4-0. They are 3-3-0 on the road.
The Canucks lost for the second time in as many nights and saw their record fall to 4-5-1. The Stanley Cup finalists have given up the opening goal eight times in 10 games and have held the lead going into the third period just once.
"We can be better in a lot of areas," said coach Alain Vigneault. "We're not generating the type of chances that I think this group is capable of generating.
"We're playing under our level right now."
Schneider played well in his fourth start of the season. He looked confident and always seemed to be in position. He was frustrated over allowing Steen's second goal, a long shot from the boards, just above the faceoff circle, which made the score 2-0.
"The second goal was just a back-breaker for our team," said Schneider, who made 28 saves but saw his record fall to 2-2-0. "It sucked the wind out of our sails.
"It was frustrating for me not to keep our team closer."
After sleepwalking through the first two periods, the Canucks outshot the Blues 17-6 in the third but couldn't beat Elliott.
"We faced some pressure," said St. Louis coach Davis Payne. "You're going against a good hockey team that can make some pushes.
"Els was sharp back there. He had to make some key saves."
Steen has scored five goals in eight games. He also has nine goals in 15 career games against Vancouver.
"It's always fun playing the Canadian teams," said Steen. "You get pumped up for the games."
The Canucks played the second of back-to-back games after losing 3-2 in Edmonton Tuesday night. Luongo started that game but was pulled after allowing three goals on four shots in a five-minute span in the second period.
Both the Blues and Canucks have seen their starting goaltenders struggle.
Luongo, a Vezina Trophy nominee last year, has a 2-3-1 record and has allowed 19 goals for a 3.46 goals-against average. The Blues' Jaroslav Halak is 1-4 and has a 3.47 goals-against.
