Ryan Pulock gave New York a 2-1 lead at 19:15 with his first goal since Oct. 22 (30 games). Following an offensive zone face-off win, Pulock scored from the top of the left circle.
Raty extended the lead to 3-1 at 7:10 of the third period when he cut to the slot and shot over Bobrovsky.
"I didn't realize I made a move there," Raty said. "I just thought I got the puck and shot it. I felt like I almost blacked out. Yeah, it felt great."
Zach Parise made it 4-1 on a backhand at 8:21 before Beauviller scored his eighth of the season into an empty net at 15:50 for the 5-1 final.
"This was important," Lee said. "The back-to-back, and after last night dropping that one late in the game, it was imperative that we came out with the right mindset, and we did that from the puck drop. Just played a really solid game."
