Jason Dickinson answered with a power-play goal for the Blackhawks with 9:40 remaining in the period. Dickinson collected the puck to the left of the net after an initial save by Anderson and tossed it toward the goal line. Multiple players collapsed toward the puck, eventually pushing it across.

Chicago pulled ahead on goals from Sam Lafferty and Taylor Raddysh scored 1:31 apart. Like the goal from Dickinson, both were scored amid scrambles inside the blue paint.

Thompson scored his first goal with 8:05 remaining. Okposo took a shot from long-range and Thompson buried the rebound from the blue paint:
