Has a FIBA World Cup game ever ended 70-47?
Exactly once. On September 3, 2006, Spain beat Greece 70-47, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 70-47 in league history.
That makes 70-47 the 475th most common final score out of 1,178 that have ever occurred in FIBA World Cup. One point away, 71-47 has happened never and 70-48 has happened never.
