The second period was busy as Vancouver came out with a desperate effort early on and managed to equalize the score, but the Avalanche stayed the course and eventually capitalized on a power play to take a 3-2 lead heading into the final frame.
The Canucks seemingly tied the game up just over midway into the period as Conor Garland tipped in a point shot, but the goal was challenged by the Avalanche for goaltending interference. Upon review, it was determined that Garland was in the crease and made contact with Francouz and the goal was overturned.
Shortly after, the Canucks continued to push and were rewarded at 10:34 as Horvat, their captain, tipped a point shot from Ethan Bear past the far side of Francouz.
The Avalanche received a lengthy power play as Tyler Meyers high-sticked Rantanen in the slot at 12:31. The stick struck Rantanen's face and drew blood - as the winger did not return for the remainder of the period, but returned for the third - and thus, Colorado received a four-minute power play.
At 14:56, the Avalanche's power play improved to a 5-on-3 for 1:36 as J.T. Miller was called for hooking.
On the subsequent sequence, MacKinnon fired some blistering one timers on net, but couldn't beat Martin. Makar even struck the crossbar with a sizzling shot of his own, but the Avalanche finally lit the lamp as Compher found Makar and he and MacKinnon exchanged a quick pass before Makar blasted a 93.6 mile-per-hour one timer past Martin from the left faceoff circle at 15:59.
