Lightning coach Jon Cooper said it was the latest display of Point's skill and toughness.
"His determination … it's impressive, his will to succeed," Cooper said. "He's a difference-maker, and difference-makers do things like that."
Brandon Hagel made it 4-0 at 8:31 of the third period with a follow up from in front of the net after an initial shot from Zach Bogosian.
"There are some guys that aren't afraid of the area, and some guys that stay away from that area," Cooper said. "[Hagel] is a true competitor. There's guys that have a little bit of 'dirt under their nails,' and Hags is one of those guys. It really works in his favor."
Guhle ended Vasilevskiy's shutout with 2:39 remaining for the 4-1 final.
"It was nice to score, and to get one on the board is good going into tomorrow," Guhle said. "Maybe we'll have a little bit of a better feeling going into tomorrow. No time to think about this one."
