Early in the first, Jarret Stoll was clipped with a high stick by Kurt Sauer which put the Oilers on the power play.
On the power play, the best scoring chance went to the Avalanche as Ales Hemsky
was stripped of the puck by Antti Laaksonen trying to keep it in along the blueline. It was pushed forward to Colorado's Mark Rycroft who attempted a backhand deke but was denied by Roloson.
Midway through the period, Horcoff made a nice pass to Hemsky on the rush and Hemsky's shot attempt was blocked but it went back to Ladislav Smid
who had a clear shot on net. His blast was blocked by Avs netminder Peter Budaj.
With 4:29 left in the first, Marc-Antoine Pouliot fanned on a shot from the high slot that was going wide until Budaj tried to smother the slow-moving puck with his glove and knocked it into his own net.
Follow the goal, the line of Pouliiot, Petersen and Jacques had several other chances to score. Pouliot had a chance from the top of the crease but it was stopped by Budaj.
Several minutes later, the Avalanche struck to tie it up. A screened Dwayne Roloson couldn't see the puck and over-committed to Brett Clark who dished it over to Milan Hejduk for a one-time blast.
After one period, shots on goal were 9-7 in favour of Edmonton.
Colorado scored a bit of a weird one early in the second to move the Avs in front 2-1. John-Michael Liles dumped the puck in and Roloson had trouble handling the puck. He dove to try and recover the rebound but Liles got there just ahead of him to poke it in.
Midway through the second, the Avs doubled their lead when Andrew Brunette made a nice move to get around Ladislav Smid
before centering the puck to Wojtek Wolski. Wolski simply put the puck into the open cage as Roloson could not get across in time.
As Edmonton desperately tried to get back in the game, Raffi Torres dropped the puck to Steve Staios on a rush but his shot hit the midsection of Budaj.
After two periods, shots on goal were 15-13 in favour of the Oilers.
Edmonton went on its second power play of the night early in the final frame but the best chance once again went to Colorado's Mark Rycroft. Rycroft intercepted a cross-ice pass from Bergeron and then broke in alone on Roloson. Stoll upended the Avs winger, ending the power play but potentially saving a goal.
On the ensuing four-on-four situation, Sakic found Tyler Arnason in the high slot and he flicked it past Roloson to put the Avalanche in front 4-1.
Following the Colorado power play, Craig MacTavish put Jussi Markkanen in goal, replacing Roloson.
During an Edmonton power play, Ales Hemsky
was rattled hard into the boards and skated to the bench slowly but he did come back to play later in the period.
Marty Reasoner an an opportunity to score the Oilers' second goal but was hauled down by Arnason as he cut across the Avalanche net.
