Has a FIBA World Cup game ever ended 74-65?
Exactly once. On August 13, 1994, Argentina beat Spain 74-65, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 74-65 in league history.
That makes 74-65 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 75-65 has happened 1 times and 74-66 has happened 2 times.
