Has an AFL game ever ended 89-22?
Exactly once. On May 16, 1903, Fitzroy beat Sydney 89-22, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 89-22 in league history.
That makes 89-22 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 90-22 has happened never and 89-23 has happened never.
