Has an AFL game ever ended 90-33?
Exactly once. On June 24, 1933, St Kilda beat Melbourne 90-33, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 90-33 in league history.
That makes 90-33 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 91-33 has happened never and 90-34 has happened never.
