The following is excerpted from the Little League International webpage regarding the decertification of the Meta BBCOR 33", and can be found at https://www.slugger.com/en-us/2020-meta-33-update.
The NCAA recently conducted additional testing of the previously-certified 33 in./30 oz. Louisville Slugger 2020 Meta (-3) BBCOR baseball bat. The conclusion of this additional testing resulted in the NCAA and the National Federation of State High School Associations (NFHS) removing this specific model from their approved-for-play bat list. At this time, no other sizes of this bat model, or any previous model years of the bat model, have been decertified.
To help minimize any inconvenience you may experience due to these decisions, we are offering immediate assistance to players and families who own the 33” length of the 2020 Meta (-3) BBCOR bat. Our team immediately initiated the process to ensure the quickest and most effective response possible.
We apologize to all players impacted by this development and we are committed to getting an industry-leading bat back in your hands as soon as possible. Our customer service team is available to answer any questions you have about which bat is right for you. They can be reached at 1-800-401-7908 and via the online contact form.
