- AABC’s own site publishes an Approved Bats page explaining USABat.
- Non-wood youth bats need the permanent USA Baseball mark; solid one-piece wood may be used with or without it under USABat guidance.
AABC spans many age brands. We have not reproduced every adult/stan-level bat rule here — open your division’s current AABC rulebook before buying.
