Has a FIBA World Cup game ever ended 101-57?
Exactly once. On August 20, 2006, Spain beat Panama 101-57, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 101-57 in league history.
That makes 101-57 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 102-57 has happened never and 101-58 has happened never.
