"I think that's what we've been talking about all year," Maroon said. "Especially on that stretch we had where it's just when someone scores, you've got to find a way to bounce back, get the next one. Our line went out there, got back to our game, grinding them down low, getting high to low, screens in front and found a way to get the rebound. [Robert] Thomas made a heck of a play with his skate, making that pass. So we found way to get it done tonight."
Barbashev completed the hat trick with an empty-net goal to extend the lead to 5-2 at 19:11.
"I thought it was a grind the whole game pretty much," Blues coach Craig Berube said. "Not a very clean game. Fourth line, excellent game, did a real good job for us."
