They surrendered a goal to forward Darren Helm with 5.6 seconds remaining in regulation and saw their season end in a 3-2 loss to the Colorado Avalanche in Game 6 of the Western Conference Second Round at Enterprise Center on Friday.
Two nights earlier, in Game 5 at Ball Arena in Denver, Colorado forward Nathan MacKinnon scored with 2:46 left in regulation to give the Avalanche a 4-3 lead and possibly put the game and the series away. Instead, Blues forward Robert Thomas scored the tying goal with 56 seconds left in regulation and forward Tyler Bozak won it 3:38 into overtime to give the Blues hope in Game 6.
It appeared Game 6 was heading for overtime as well, that is until Helm, in his 14th NHL season, stunned the crowd and handed the Blues their third home loss of the series.
For Helm, it was a signature moment in a long career as a bottom-six forward. In his first 91 games in the Stanley Cup Playoffs, the 35-year-old had scored 11 goals. Among them was the series clincher for the Detroit Red Wings in the 2009 Western Conference Final against the Chicago Blackhawks on May 27.
