Bunting pushed it to 5-3 with a slap shot at 18:48.
The Penguins were outshot 12-5 in the second.
“The first two things we talk about with our players is attitude and effort,” Pittsburgh coach Mike Sullivan said, “because those are the two things that you have complete control over. So, when it’s not going the right way, part of the solution is always to simplify.”
Crosby’s empty-net goal made it 6-3 at 17:30 of the third period before Blake Lizotte scored on the power play with 12 seconds remaining for the 7-3 final.
“It’s big for us, especially playing a team like Philly,” Rakell said. “We know that we’re going to play them a lot, and a lot down the stretch. We’re just feeling good about ourselves going into this (holiday) break and just regrouping and getting away from it a little bit. Then just come back even better.”
