Has an NCAA Baseball game ever ended 6-6?
Exactly once. On January 1, 1996, Utica and Colgate drew 6-6, and no NCAA Baseball game before or since has ended that way. When it happened it was a scorigami, the first 6-6 in league history.
That makes 6-6 the 457th most common final score out of 531 that have ever occurred in NCAA Baseball. One point away, 7-6 has happened 6,506 times and 6-7 has happened never.
