Watch: Mantha ties Centennial Classic in final seconds as Leafs blow 4-1 lead

The Red Wings did it.

Down 4-1 in the third period of the Centennial Classic in Toronto, Detroit stormed back, and Anthony Mantha scored the tying goal on a scramble in front with officially 1.1 seconds left on the clock.

Indoors, outdoors, when the Maple Leafs are up 4-1, bad things happen.

Toronto eventually came out on top, winning 5-4 in overtime on Auston Matthews' 20th goal of the season. But Detroit at least got a point.
