Has an Olympic Basketball (Men) game ever ended 110-81?
Exactly once. On July 26, 1980, Spain beat Brazil 110-81, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 110-81 in league history.
That makes 110-81 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 111-81 has happened never and 110-82 has happened never.
