Has a FIBA World Cup game ever ended 79-57?
Exactly once. On May 14, 1963, France beat Canada 79-57, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 79-57 in league history.
That makes 79-57 the 475th most common final score out of 1,178 that have ever occurred in FIBA World Cup. One point away, 80-57 has happened never and 79-58 has happened never.
