Has an AFL game ever ended 154-13?
Exactly once. On June 26, 1926, Melbourne beat Hawthorn 154-13, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 154-13 in league history.
That makes 154-13 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 155-13 has happened never and 154-14 has happened never.
