Kirill Kaprizov scored his fifth goal of the series, Matt Boldy got his first career playoff goal, and Marc-Andre Fleury made 29 saves for Minnesota, the No. 2 seed in the Central.
"Well, the vibe right now, of course, when we lose a game is not the best," Wild forward Frederick Gaudreau said. "The vibe is, it's 2-2. Like we said earlier, it's not going to be easy, it's the playoffs, and the Blues are a good team."
Kyrou gave St. Louis a 1-0 lead at 4:19 of the first period, scoring on his own rebound after Fleury could not control the initial shot.
"Yeah, it's definitely nice to get the first goal," Kyrou said. "It's a huge confidence builder for the team, especially here at home. The crowd was unbelievable tonight and it definitely got us going."
Kaprizov tied it 1-1 at 14:06 on Minnesota's fourth shot of the game, a one-timer from the left circle off a pass from Jared Spurgeon.
The Wild were outshot 18-5 in the first.
"We just felt we got disrupted a little early in the game, obviously, with [a] four-minute (minor to Kevin Fiala at 8:42 of the first period) and … then another high stick (on Joel Eriksson Ek) and then 4-on-4, so, the first period, we wanted to get to our game, and we weren't able to get to our game because of that," Minnesota coach Dean Evason said.
"But having said that, we've got to stay out of the box too. It disrupted everything. ... It disrupts the flow of the game, disrupts what we want to do, what we want to get to, 5-on-5, right? But having said that, we have to find a way to get to it. We did get momentum from those kills. So, we didn't do enough to get to our game, but [the penalties] hurt us early as well."
The Blues were 1-for-4 on the power play; the Wild went 0-for-4.
