In regulation, despite having three power play opportunities - and a 15-11 shot advantage - the Avalanche went 0-for-3 in the first period and trailed the Oilers 1-0 heading into the first intermission.
After coming out with a dominant start and outshooting Colorado 5-1 through four minutes, Edmonton took back-to-back power plays early in the game, both of which were penalties from Foegele at 4:13 (interference on Nathan MacKinnon) and at 6:24 (for tripping on Bowen Byram).
The Avalanche's power play units were stifled - with Devon Toews firing off four shots - and instead, the Oilers drew the game's icebreaker late in the frame with a goal from Foegele. On a defensive zone breakdown and after winning a wall battle, Edmonton quickly countered sending the puck from Ryan McLeod at the half wall to the near-side netfront for Janmark. The winger took the puck, spun and split MacKinnon and Josh Manson to the backdoor for Foegele to tap it in past Georgiev at 15:08.
The Avalanche concluded the opening frame with a power play that was awarded at 18:00, but did not convert.
The second period unfolded with a riveting barn burner exchange as five goals were scored; three from the Oilers and two from the Avalanche.
Edmonton increased its lead 3-0 with two early goals from Foegele and Draisaitl. Just 1:14 into the middle frame, Ceci rimmed the puck around the boards and Darnell Nurse corralled it at the half wall before centering it to Foegele, who beat Georgiev in-tight with his second goal of the afternoon.
The Avalanche had the chance to capitalize with their fourth power play of the game as Ryan Nugent-Hopkins was called for holding at 5:22, but Colorado couldn't convert.
Edmonton then upped its lead 3-0 at 7:37 on a quick passing sequence as Nugent-Hopkins' penalty expired, he joined his team regain possession as he exited the box, threaded a pass to Draisaitl at the lower right faceoff circle, where the German centerman beat Georgiev with a one-timer from the sharp angle.
Less than a minute later - 57 seconds - MacKinnon put some life into his team as he carried the puck around the net, curled up to between the circles and wired a wrist shot that grazed the a netfront screen by Compher - who was credited with the goal - and past Campbell to trim Colorado's deficit down 3-1 at 8:34.
