Blues rough up Avalanche

~ Shattenkirk burns his former team with a goal and two assists

ST. LOUIS -- Kevin Shattenkirk took advantage of a chance to show off against his former team.

The St. Louis defenseman had a goal and an assist, Andy McDonald added a goal and two assists, and the Blues beat the Colorado Avalanche 3-1 on Tuesday night.

David Backes also scored and Jaroslav Halak stopped 26 shots to help St. Louis win for the fifth time in the last seven games. The Blues also snapped a seven-game losing streak to the Avalanche, beating Colorado for the first time since April 12, 2009.

Shattenkirk, sent to St. Louis along with Chris Stwart on Feb. 19 in a deal for Erik Johnson and Jay McClement, was looking forward to showing the Avalanche they made a mistake in trading him.

"I wanted to get out there and prove that I found my niche here," said Shattenkirk, who has two goals and 14 assists with the Blues. "It has been a blast."

Kevin Porter scored his career-best 14th goal of the season for the Avalanche, who have lost six of seven and 16 of their last 19.

Shattenkirk converted on a 5-on-3 power play at 4:07 of the second period to give the Blues the lead for good at 2-1. It was his ninth goal of the season.

McDonald, who assisted on the first two goals, added an empty-netter with 40 seconds to go.

St. Louis coach Davis Payne said Shattenkirk has been a welcome addition to the back line.

"He's got a lot of confidence with the puck," Payne said. "He has the ability to take that extra step, to create that extra lane. With a guy like that, he's always got his head up shooting."

Shattenkirk helped get the Blues off to a 1-0 lead by setting up the first goal late in the opening period. His shot from the blue line deflected off the stick of Backes, who was camped in front of the net. Shattenkirk said he threw the puck on the net hoping Backes could make contact. Backes has a team-high 30 goals and four in his last six games.

"I've been pretty good at finding him and he's been pretty good at finding the back of the net," Shattenkirk said.

Colorado tied the game less than 2 minutes later on Porter's tally.

But Halak rallied to stop the final 16 shots after the goal. He made three key saves in the final two minutes.

The victory helped the Blues break a painful losing streak against Colorado, which outscored St. Louis 35-17 during the seven-game run.
