Has an AFL game ever ended 140-58?
Exactly once. On June 1, 1946, Essendon beat St Kilda 140-58, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 140-58 in league history.
That makes 140-58 the 3885th most common final score out of 6,649 that have ever occurred in AFL. One point away, 141-58 has happened never and 140-59 has happened never.
