Has a FIBA World Cup game ever ended 69-68?
Exactly once. On August 10, 1990, Australia beat Brazil 69-68, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 69-68 in league history.
That makes 69-68 the 475th most common final score out of 1,178 that have ever occurred in FIBA World Cup. One point away, 70-68 has happened 3 times and 69-69 has happened never.
