Colorado received a 5-on-3 as Henri Jokiharju was called for holding at 7:45 and Owen Power was whistles off for high sticking at 7:50. On the Avalanche power play, MacKinnon grabbed a pass from Makar in between the circles, sidestepped a Buffalo forward and sniped his shot past Luukkonen's glove for the 2-2 equalizer at 9:00.
The Avalanche then regained the lead as their power play continued as they hemmed Buffalo in their own zone. MacKinnon fired a shot on net, Luukkonen made the stop, but the puck bounced out to Lehkonen at the doorstep, who put the loose puck into the net to give Colorado a 3-2 lead at 9:49.
With momentum from back-to-back power-play goals, Colorado didn't let up and extended its lead 4-2 at 11:53 with a strike in transition by MacKinnon. As the Avalanche jetted up ice, Makar snapped a pass across the slot to MacKinnon, where the centerman buried his second goal of the night by zipping his shot over Luukkonen's glove.
