Farabee extended the lead to 3-0 at 7:44 of the third period, scoring off the rush from the left circle.
"I think players, when they get some points, always helps their confidence," Tortorella said. "We're trying to get [Farabee] playing better by giving him minutes (18:49).
"I think he's been a little behind because of a lack of playing time during camp. Hopefully, that will release him a little bit. He scores a big goal, the third one, so little by little. I don't think he's playing great, but I think when forwards get points, it helps their game."
Duchene scored from the right circle during a 6-on-4 at 17:42 for the 3-1 final.
Predators defenseman Mark Borowiecki was stretchered off the ice at 6:24 of the second period after being hit behind Philadelphia's net by forward Morgan Frost. No penalty was assessed on the play.
The Predators later tweeted that Borowiecki was conscious and had movement in all of his extremities when he left the arena. He was transported to Vanderbilt University Medical Center, where he will undergo further testing and observation.
"It's never comforting when you see a player or teammate go down in that fashion," Hynes said. "I think when you saw it right away, when he hit the boards and then he went right down, you could tell it was a serious incident. He's such a great guy, a big part of the team.
"It's nice to see that it looks like he's going to be OK from the serious part of the injury. Obviously, he's going to be banged up here for a little bit, but it's … nice to see him be OK and be able to get back on the mend."
