The power play was the story tonight for the Blues as Christ Stewart, a former member of the Avalanche, scored his 100th career goal to give St. Louis a 1-0 lead 11 minutes into the first period.
Two minutes into the second period Patrik Berglund added a power play goal to give the Blues a 2-0 lead as Berglund scored his first goal in 10 games with a redirect from Jay Bouwmeester. Three minutes later, Andy McDonald scored his sixth goal of the season as the Blues took a 3-0 lead.
The Avalanche's lone goal was credited to Cody McLeod with 4:47 left to go in the second period.
Brian Elliott got the win tonight for the Blues stopping 17 shots as he bounced back after a tough game Sunday night at Colorado, allowing four goals and getting pulled in the second period.
The Blues now only have two regular season games left against the Flames and Blackhawks both at home as they are still vying for home-ice advantage once the playoffs get underway.
It will sure be an exciting time in St. Louis as playoff hockey gets underway.
