Has an Olympic Basketball (Men) game ever ended 98-59?
Exactly once. On August 4, 2012, Brazil beat China 98-59, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 98-59 in league history.
That makes 98-59 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 99-59 has happened never and 98-60 has happened never.
