The Marlies received a personnel boost from debutants Max Ellis and Graham Slaggert plus the return of Marc Michaelis following a long-term injury.
In net, Michael Hutchinson cut out the weak goals that have marred his recent performances.
The Marlies also competed for the full 60 minutes and took just two penalties while finding a breakthrough on their struggling power play in the first period.
“A good response from yesterday,” said Greg Moore. “We were able to sustain the good start. Special teams were improved. Our power play got us a couple early to build the momentum for us.
