Bunting extended the lead to 3-1 on a power play when he tapped a loose puck into the open net 34 seconds into the second period.
"It's obviously a different look with the five forwards. We've had some opportunities, have done some good things," Tavares said. "The other unit's done really well and contributed, and you need that. So great to see them get some big goals and find some continuity as well. And then for us to kind of just stay with it and continue to create good looks and obviously get rewarded tonight."
Devon Toews cut the lead to 3-2 at 9:45 after his redirection of Compher's shot caromed off the skate of Matthews in the crease.
Matthews extended the lead to 4-2 at 15:00 when he backed away from Georgiev and waited for the goalie to commit before shooting.
"I just tried to get the forecheck a little bit and try to force their guy to maybe make a play that he's not comfortable with," Matthews said. "'Willy' (Nylander) made a nice read to jump it. Gave me a lot of time in front of the net. Just tried to sneak it in."
TJ Brodie pushed it to 5-2 when his shot from the blue line beat Georgiev far side at 15:24, and Bunting scored an empty-net goal at 16:11 of the third period for the 6-2 final.
