"As soon as the third one went in our team went dead," Ruff said. "This time of year and knowing where we are at, all you can try to do is go out there and win your shift."
Ritchie made it 3-1 at 5:42, finishing off a nice passing play by Adam Cracknell and Curtis McKenzie on a rush up the middle.
Desharnais made it 4-1 at 9:30, taking a long bounce off the end boards off a shot from Anton Slepyshev and shoveling the puck past Niemi. Maroon put the Oilers up 5-1 at 11:29.
"All in all, a good game," Maroon said. "We did some good things and some confidence will build. [Pouliot] got a huge goal, and he needed that. He's been working hard all year, he deserves that goal. Nurse got on the board tonight. [Desharnais'] line was really good tonight. It's all good to see."
Nugent-Hopkins scored at 12:17 of the third period when a centering pass bounced in off his skate. McDavid scored at 14:00, converting a pass from Maroon on a 2-on-1 rush.
"It's embarrassing," Stars forward Patrick Sharp said. "I'm embarrassed and I'd like to think my teammates are embarrassed as well. Hopefully we can be a lot better on the rest of this trip."
