Nick Cousins scored, Juuse Saros made 29 saves, and Matt Duchene scored the only goal in the shootout for the Predators (4-3-0), who swept the back-to-back set. Nashville won 3-2 in overtime here Tuesday.
"I just see commitment," Duchene said. "I see guys that have taken a step in their commitment to playing both ways and blocking shots. I think it's pretty easy to commit to that with our group because I think there's an accountability in our room. I think our leadership and our togetherness is even better this year than it was last year, and I feel guys are playing for each other. I think that's so important. I know when I go out on the ice, the last thing I want to do is let my teammates down. You want to play for them and perform for them, and it doesn't matter what it is."
Ryan Carpenter scored, and Kevin Lankinen made an NHL career-high 41 saves for the Blackhawks (2-3-3), who extended their point streak to five games (2-0-3).
"As a team, we played better tonight," Lankinen said after his fourth NHL game. "It was too bad we couldn't get the win. We had good chances in the overtime. Maybe another night we get a bounce and it goes in. But for me, I felt confident. I felt good out there."
