But does it apply to USSSA or USA? USSSA (and the 2018 Clarification) doesn't make reference to indifference or how to score it - I didn't see any reference in the USSSA pdf about "if not addressed here, [OBR, NFHS, NCAA] rules apply". I think LLB defers to OBR - does NCAA or NFHS do anything similar?The softball rules don't make reference to "defensive indifference". Hmmm...I just learned something new.
