Chris Stewart's goal in the eighth round of the shootout Friday gave Colorado a 4-3 win over Chicago and kept the Avalanche unbeaten at home this season.

Stewart beat Chicago goalie Antti Niemi on the blocker side to nail down the win after both sides scored earlier in the shootout.

Rookie Ryan O'Reilly scored two goals in regulation for the Avalanche and David Jones added the other. Craig Anderson made 29 saves.

Dustin Byfuglien had a goal for Chicago but was denied by Niemi in the Blackhawks' final try in the shootout. Duncan Keith and Andrew Ladd also scored for the visitors.

Chicago took a 2-0 lead in the first period, but Colorado stormed back with three consecutive goals to make it 3-2. Colorado had just three shots on goal in the second period, but scored on two of them.

Ladd scored on a rebound with 3:20 to play in the second period to tie the game and force a scoreless overtime period.
