Boris Katchouk gave Chicago a 1-0 lead at 12:56 of the second period, jamming the puck into the net after Oettinger saved a breakaway attempt by Zach Sanford.
“I think we played on our heels a little bit,” Katchouk said. “We got a little too comfortable with that 1-0 lead, and I'm a culprit of it too. But the little chips, it's always the little battles and the little things that you need to do to make your team win. And it's those little battles that really helped and we didn't really do it.”
Duchene tied it 1-1 on the power play at 2:32 of the third period. He put a wrist shot past Mrazek from the top of the left face-off circle with Jamie Benn providing a screen in front of the net to extend his goal streak to three games.
“I felt like Mrazek was playing great,” Benn said. “He saw a lot of pucks, and I don’t think we made it too tough on him in the first two periods, so we wanted to get some screens and get more pucks there. We did that.”
Marchment put the Stars ahead 2-1 at 14:54, getting around Blackhawks defenseman Seth Jones at the blue line and putting a wrist shot between Mrazek's pads.
“I was definitely thinking shoot,” Marchment said. “I just kind of saw a little opening in that five-hole and lucky it went in.”
