Backlund jumped onto the ice while the Blues were moving the puck around the Flames' zone and he immediately used his stick to disrupt the play. He then carried the puck up the ice to the Blues' end and eventually capitalized with a quick shot past Allen to give the Flames the first goal of the game.
"I think tonight was one of the best games I've seen Backs play," linemate Matthew Tkachuk said. "And last game in Nashville, it was one of the best games I've seen Fro (Michael Frolik, the third member of the line) play, if not his best one. I think this road trip was maybe good to get our mojo back a little bit."
After Backlund's ice-breaker evened things up for the Blues when he wristed the puck far-side past Lack.
A couple of penalties cost the Flames in the second period as Schwartz and Pietrangelo scored back-to-back powerplay goals to allow St. Louis to claim the lead. With Sam Bennett sitting in the box for tripping, Vladimir Tarasenko's shot ringed off the post and back to him. He spotted a wide-open Schwartz, who made it an easy tap-in to make it 2-1 for the Blues.
Then, with Frolik off on a hooking call, Pietrangelo snapped the puck past Lack for the multi-goal lead.
"So, two nights in a row we've given up two-for-three, two-for-three on the powerplay," coach Glen Gulutzan said. "When you're playing your back-to-backs, your penalty kill has to be better. Our penalty kill, quite frankly, doesn't look anything near what it should, and we've got to clean that area up. Because tonight it put us in a hole. Nashville, it put us in a hole. Tonight, we couldn't get out of it.
"The biggest issue with the penalty kill right now is our zone entries. We are not stopping people. They're walking into our zone uncontested, setting up. And if you're going to let somebody stay in your zone for two minutes, you can't get a clear, but if you can't even stop them from coming in, you're going to get scored on. That's just the nature of the game. I like our in-zone kill; being organized at the blueline right now and denying entires is not where it needs to be. It's not NHL level, and we've got to get it there."
