The Blues challenged for goalie interference, but it was determined after video review that Marco Scandella and Hugh McGing caused Sam Steel to make contact with Binnington.
"I agreed that our guy initially pushed their player in, but before contact, I thought their player got his hands up on 'Binner' and pushed off, which made him turn,” Bannister said. “And he wasn't obviously, one, to make the save, but because of that, he wasn't squared to the puck either.
“That was my call and I guess for me, it's a learning experience, but I felt even after the fact of the push, if he would have just went into our goaltender, I wouldn't see reason to challenge. But because he got his hands up and he pushed him, I felt there was a reason to challenge."
Brandon Saad cut it to 2-1 with a power-play goal at 12:53 on a one-timer from the left circle off a backhand flip pass by Kyrou off the left wall. It was his third straight game with a goal, and ended St. Louis' drought of 20 consecutive power plays without a goal.
"The power play, it's a big goal," Bannister said. "I know it made it a 2-1 game, but in a broader spectrum, it's a big goal for that group."
