Calgary, AB (SportsNetwork.com) - Alexander Steen scored twice and Brian Elliott made 25 saves for his fifth shutout of the season as the St. Louis Blues topped the Calgary Flames 4-0 on Tuesday.

David Backes posted a goal and two assists, Jori Lehtera also scored and T.J. Oshie supplied two assists for the Blues, who have won five of their last six games.

Elliott turned aside six shots during the first period, 11 in the middle stanza and eight more in the third for his 30th career whitewash.

"Our goaltending has really been the story for the last 10 days or so," said Blues coach Ken Hitchcock. "These guys have given us a chance to win every night."

Jonas Hiller allowed three goals on 25 shots in Calgary's second straight loss.

"They played quite a game," said Flames coach Bob Hartley. "That's probably the best team, the deepest team, that we've played lately."

After a scoreless opening stanza, Steen put the Blues on the board with 8:28 left in the second. Steen skated up to the right circle and wristed a shot over Hiller's glove.

Lehtera increased St. Louis' lead to 2-0 just 1:18 into third. Vladimir Tarasenko stripped a defender of the puck and slipped a pass back to Jaden Schwartz, who had his cross-ice feed one-timed into the net by Lehtera.

Steen netted his second of the night on a slap shot prior to the midway point of the final stanza.

The Flames pulled Hiller with over eight minutes to play. After briefly returning to the net, the Calgary netminder was pulled once again and Backes sealed the outcome by scoring on the vacated cage.
