Has a FIBA World Cup game ever ended 108-65?
Exactly once. On August 8, 1990, Australia beat China 108-65, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 108-65 in league history.
That makes 108-65 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 109-65 has happened never and 108-66 has happened 1 times.
