1918: The Toronto Arenas defeat the Vancouver Millionaires 2-1 in the final game of their best-of-5 series to become the first NHL team to win the Stanley Cup.

The Arenas, who later would be renamed the Toronto St. Patricks and then the Maple Leafs, win the inaugural NHL championship and earn the right to play the Millionaires of the Pacific Coast Hockey Association in a Stanley Cup challenge.

The different rules used by the leagues present a problem: The NHL uses six players on the ice while the PCHA employs a rover as a seventh player. An agreement is reached: PCHA rules will be used in even-numbered games, NHL rules employed in the odd-numbered games.

The Millionaires win Games 2 and 4 playing seven a side. Toronto sweeps Games 1, 3 and 5 with one fewer player on the ice.

Alf Skinner scores eight goals in five games for Toronto. Cyclone Taylor scores nine goals for Vancouver.
