Tomasino put the Predators ahead 3-2 at 15:59 of the third period with a wrist shot from the left face-off circle.
"I'm proud of him," Brunette said of Tomasino. "From where we started the year ... it was a little bit of work to get him to play to a certain pace and understand kind of my expectations of him. And he put the work in. He's been playing exceptional here the last month or so. It was nice to see him get rewarded tonight because he's had so many good looks and he was driving a lot of offense for us."
Nyquist scored an empty-net goal for the 4-2 final at 19:59.
"They had the better of play in the third period, but we're holding on and we just can't keep it simple," Flyers coach John Tortorella said. "When it comes down into late in the third period, its who blinks first, and we blinked a number of times and didn’t give ourselves a chance to win.”
