Buchnevich cut it to 2-1 at 1:59 of the second period. Parayko intercepted the puck along the right boards, curled around the net and found Buchnevich in the left circle for a one-timer.
Arvidsson responded to make it 3-1 at 6:04. Binnington steered aside a soft shot from Lohrei, but Arvidsson skated into the rebound near the right wall and beat the Blues goalie over his left shoulder with a slap shot.
“It bounced off the wall, too,” Arvidsson said. “I saw some guys going to the net, so I figured I’d try and shoot it. I hit it pretty clean, so it was nice to see it go in.
“It’s always nice to get a goal. I think as a line we had a little bit better game this game than in Detroit (a 5-4 loss to the Red Wings on Tuesday). We’ll just move on from there and try to be even better the next game.”
Zacha pushed it to 4-1 at 12:26, cutting toward the high slot between two Blues defenders and roofing a shot over Binnington’s glove.
Zacha scored his second on a power play with 0.2 seconds remaining in the period. Lindholm collected a rebound near the left post and passed across the crease to Zacha, who buried the puck into the open net to make it 5-1.
“I looked up and [the clock] was zero, so I wasn’t sure,” Zacha said. “But when we were skating by the bench they were telling me it was in. That felt good. Especially at the end of the period, that kind of puts teams down going into the locker room. I was happy that one went in.”
Suter made it 5-2 at 9:07 of the third period. Korpisalo made a highlight-reel save with his right pad on Dylan Holloway, but the Blues forward got the rebound right back, circled the net, and passed out front to Suter.
