Joona Luoto scored his first NHL goal for the Blue Jackets (24-46-8), who have lost six of seven. Michael Hutchinson allowed five goals on 24 shots before being replaced by Jon Gillies in the third period. Gillies made nine saves on 12 shots.
"You can see the result out there. It wasn't the best hockey we've been playing," Luoto said. "They kept scoring and scoring. We didn't do anything. It's tough to lose 8-1. It's unacceptable."
Hughes gave the Devils a 1-0 lead 1-0 at 11:35, scoring unassisted on a break before Tomas Tatar made it 2-0 at 1:20 of the second period.
"Those games are fun to play when you see everybody's doing well and everybody's producing, so it was a good night," Tatar said.
Hughes extended it to 3-0 at 2:10, scoring on the power play from a low angle from the right side of the net.
Hughes has 95 points this season (42 goals, 53 assists), pulling within one of tying Patrik Elias (2000-01) for the Devils franchise record for points in a season.
"The better I do, the better the team does," Hughes said. "Of course, you want that record and I'm going to be here for a lot of years, so I'd like to break it this year, but let's see what happens."
