"Obviously, you want to be playing your best going into the playoffs and there's a couple of teams we still want to catch, and home ice would be huge for us," Blues center Tyler Bozak said. "We can keep climbing, so we'll keep our foot on the gas, keep trying to catch those teams to get into a better position."
Jake Allen made 25 saves for the Blues, who are 6-1-1 in their past eight games. He is 7-0-0 against the Devils for his career.
"It's about sticking with it to the end and giving up the least amount of offense as we can to the other team," Dunn said. "Jake Allen and [Jordan Binnington] are doing a great job stopping the puck for us, so those are two big pieces to us getting these points down the stretch."
Cory Schneider made 24 saves for the Devils (29-40-10), who have lost 12 of their past 16 games (4-10-2) and have been eliminated from playoff contention.
