Has an Olympic Basketball (Men) game ever ended 58-37?
Exactly once. On January 1, 1964, Japan beat Canada 58-37, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 58-37 in league history.
That makes 58-37 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 59-37 has happened never and 58-38 has happened never.
