Has an AFL game ever ended 102-28?
Exactly once. On June 26, 1920, Fitzroy beat St Kilda 102-28, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 102-28 in league history.
That makes 102-28 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 103-28 has happened never and 102-29 has happened never.
