Has an AFL game ever ended 94-3?
Exactly once. On July 24, 1897, Essendon beat St Kilda 94-3, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 94-3 in league history.
That makes 94-3 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 95-3 has happened never and 94-4 has happened never.
