Has a FIBA World Cup game ever ended 76-74?
Exactly once. On August 19, 2006, Turkey beat Lithuania 76-74, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 76-74 in league history.
That makes 76-74 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 77-74 has happened 1 times and 76-75 has happened 1 times.
