The Capitals increased the lead to 3-0 with 33 seconds left in the period when Stephenson scored from the high slot off a pass from Garnet Hathaway as a fight broke out behind the Ducks net.
"I actually thought that the play had been blown down because all of the players were involved in the scrum," Eakins said. "It even looked like [Gibson] was distracted by it so, even when [the referees] were at the penalty box, I didn't think it was going to be a goal."
Among the penalties, Anaheim's Nick Ritchie received a game misconduct for being the third man in during the fight, and Hathaway received a match penalty for spitting on Gudbranson.
"It's a bad thing to do," Gudbranson said. "It's something you just don't do in a game, and he did it."
Hathaway said of spitting, "Yeah, it has no place. It was an emotional play by me. You don't plan any of that stuff in your head and it was a quick reaction and unfortunately the wrong one for me to a [Gudbranson] sucker punch."
Adam Henrique scored on the power play early in the third period for Anaheim, but the goal was immediately waved off due to incidental contact on Holtby by Rickard Rakell.
Vrana made it 4-0 when he poked in his own rebound at 5:44 of the third period.
Steel scored a power-play goal to make it 4-1 at 13:31 of the third period, and Deslauriers pulled the Ducks within 4-2 with 1:49 remaining before Wilson scored into an empty net off a pass from Carlson with 11 seconds left for the 5-2 final.
