Zach Redmond scored his first goal of the season 1:43 into the second period to give the Colorado Avalanche a 2-0 lead after the second period over the Chicago Blackhawks on Tuesday night at United Center.
Redmond received a feed from Blake Comeau, and wristed a shot past Corey Crawford.
Matt Duchene scored 14:30 into the first period to open the scoring. It was Duchene's team-leading 16th goal of the season, and the first score Crawford gave up in 155 minutes of action.
Marian Hossa looked to cut the deficit in half on a shorthanded breakaway. Hossa skated up left boards, but Nathan McKinnon's back checking slowed him down, and Semyon Varlamov made the stop to keep the two-goal lead.
With less than three minutes left in the second, Bryan Bickell also came up short. Andrew Shaw sent a feed to Bickell, who was in front of the net, but failed to elevate the puck on Varlamov.
The Hawks have killed off all three penalties, but also failed to convert on the man advantage within the first five minutes of the game. Both teams have 21 shots on goal after two periods.
