Check the model on the lists

A bat with the right mark can still be out of play if its model has been decertified or withdrawn. Find the model number printed on the bat, and look for it here.

  • USA Baseball’s decertified bats: A decertification can cover one length of a model: USA Baseball’s list names the Easton Ghost X in its 30-inch, −10 length only, model numbers YBB18GX10 and LL18GHX, and every other length and drop of that bat stays approved, since each length and drop is certified on its own. The full list of approved USA Baseball bats is at USABat.com.
  • USSSA’s withdrawn and disallowed bats: USSSA keeps a list of bats that carried its mark but were later withdrawn by their maker or disallowed by USSSA, some in certain lengths and weights only. USSSA also withdraws any BBCOR bat the NCAA or the NFHS withdraws, and any USA Baseball bat that USA Baseball withdraws.
  • The NFHS on a decertified BBCOR bat: A BBCOR bat can be decertified too. In March 2020 the NFHS ruled the 33-inch Louisville Slugger Meta composite bat non-compliant in high-school play, after the Washington State University Sports Science Laboratory advised it that the bat had been decertified under BBCOR.
