Has a FIBA World Cup game ever ended 102-70?
Exactly once. On August 31, 2002, Germany beat Algeria 102-70, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 102-70 in league history.
That makes 102-70 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 103-70 has happened never and 102-71 has happened never.
