"I tried to do that as best as possible," Kadri said. "Sometimes you've got to be patient and you've got to wait. I was able to strike early in the second period and was able to get the mojo going, in terms of individually and as a team, so it felt amazing.
"Especially to do it on the road, it was pure."
Kadri had been the target of taunts and death threats following Colorado's 5-2 win in Game 3 on Saturday, when Blues goalie Jordan Binnington sustained a lower-body injury at 6:45 of the first period after being knocked over by teammate Calle Rosen and Kadri, who was skating hard for a rebound.
No penalty was assessed on the play, but the Blues announced on Sunday that Binnington would be out for the rest of the series.
"I guess I needed some fuel. ... I was pretty upset the last couple of days, but it is what it is," Kadri said. "We got the win and that's what we wanted."

The animosity carried over into Game 4, with Kadri being confronted by Blues forward Brayden Schenn in the opening minute of the game.
Then, at 5:30 of the second period, after Blues forward David Perron attempted to hit him in the neutral zone away from the puck, he was checked into the boards by Pavel Buchnevich. As he was attempting to get up, Perron cross-checked him back to the ice before jumping on top.
Buchnevich (roughing) and Perron (cross-checking) were each assessed a minor penalty on the play.
"I figured someone was going to have something to say, but that's just stupid penalties that we cashed in on and it hurt them," Kadri said. "If you lose your cool, we'll make you pay."
Prior to the 5-on-3 power play, Avalanche coach Jared Bednar appeared to have a conversation with Kadri, who kept his composure and scored his second goal of the game on a one-timer from the right circle seven seconds after the two-man advantage expired to make it 4-1.
"I'm proud of him," Bednar said. "Our talk today and coming into tonight's game was to stay focused. We're here to win a hockey game, and I felt the guys were ready. The one guy that I was kind of concerned about was 'Naz,' but I thought he was amazing.
"Obviously, a tremendous game from him. A focus, a discipline. I'm proud of the way he's handled the last 48 hours, and to be able to come out and perform like that in the pressure situation is amazing."
