Has an Olympic Basketball (Men) game ever ended 109-79?
Exactly once. On August 6, 1992, Australia beat Germany 109-79, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 109-79 in league history.
That makes 109-79 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 110-79 has happened never and 109-80 has happened never.
