Has an AFL game ever ended 134-75?
Exactly once. On June 21, 1987, Sydney beat St Kilda 134-75, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 134-75 in league history.
That makes 134-75 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 135-75 has happened 2 times and 134-76 has happened 2 times.
