Has an Olympic Basketball (Men) game ever ended 112-75?
Exactly once. On July 26, 1992, Lithuania beat China 112-75, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 112-75 in league history.
That makes 112-75 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 113-75 has happened never and 112-76 has happened never.
