About Online Baseball Academy

Online Baseball Academy publishes guides on youth baseball equipment and player development, written for parents and coaches.

Bat certification rules differ between leagues and change over time, so we check what we publish against the governing bodies — USA Baseball, Little League, USSSA, and the NFHS — and date every guide. Sources are listed at the bottom of each one.

How we make money

Affiliate commissions, disclosed at the bottom of every page. No brand pays for placement here, and a commission never decides what we recommend.

Corrections

Rules change and we get things wrong. If something here is out of date or contradicts your league's rulebook, email support@onlinebaseballacademy.com.
