Has an AFL game ever ended 99-39?
Exactly once. On July 20, 1985, Carlton beat Melbourne 99-39, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 99-39 in league history.
That makes 99-39 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 100-39 has happened 1 times and 99-40 has happened never.
