Has an NCAA Baseball game ever ended 34-11?
Exactly once. On April 8, 1999, Hawaii beat Air Force 34-11, and no NCAA Baseball game before or since has ended that way. When it happened it was a scorigami, the first 34-11 in league history.
That makes 34-11 the 457th most common final score out of 531 that have ever occurred in NCAA Baseball. One point away, 35-11 has happened 1 times and 34-12 has happened never.
