But he wasn't done yet.
Eberle and Hall did terrific tic-tac-toe passing to get Gagner the puck, and he slapped his fourth goal of the game into a wide-open net as Emery slid to keep up with the play.
With their hats already thrown onto the ice earlier in the period, one fan resorted to throwing a shoe after the goal.
"I was hoping that would be the end of it because if he scored another one we might have seen other paraphernalia that we didn't want to see," Renney said with a laugh.
Gagner then added his eighth point of the game by making a prefect feed to Eberle, who scored his 20th of the season with 4 minutes left.
Dubnyk finished the game with 43 saves on 47 shots.
Crawford let in five goals on 28 shots. while Emery allowed three goals on 13 shots.
