Noah Cates gave the Flyers a 2-1 lead at 12:57 when he tipped in a point shot by Nick Seeler. It was his fifth game-winning goal, the most among NHL rookies.
"You get a young kid like him, and he has a lot of minutes and a lot of responsibility, but I think the main thing for me is, we all know how good of a hockey player he is, but I think his maturity is somewhere else," Deslauriers said.
Cates, a 24-year-old forward, played 19:06 on Sunday and is averaging 17:37 of ice time per game. He has 27 points (10 goals, 17 assists) in 63 games this season, including four points on the power play and two while short-handed.
"I trust him in all situations, as you see," Tortorella said. "Good for him to get rewarded with a goal. I think as his career keeps going, I think he's going to feel more comfortable in offensive situations. ... I like calling it just what it is to be a pro. I think he understands really early on. He's a little bit older than some guys coming out of college (Cates attended the University of Minnesota Duluth), but I think he understands what it is and the intangibles you need to be a pro, and he's ahead of the game there."
Laughton scored an empty-net goal at 18:12 of the third period for the 3-1 final.
