2020 Louisville Slugger Meta
The Short Answer
It depends entirely on the length. The 33 inch 2020 Meta was decertified on February 21, 2020 and is illegal in NCAA and NFHS play, with no grandfather clause. The 30, 31, 32, and 34 inch versions of the same bat remained fully approved and legal.

The 2020 Meta is the cautionary tale of modern bat certification, and if you are reading this page, you probably own one or are about to buy one used. The Meta launched as the most hyped BBCOR bat in years and promptly performed its way off the approved list; the WSU Sports Science Lab found the 33 inch version exceeded the BBCOR standard in compliance testing, and on February 21, 2020 that length was decertified for NCAA play, with NFHS following for high school. The 33 inch Meta GLD and Meta Custom variants went with it.
Here is the part that still trips people up years later: the decert applied only to the 33 inch. A 32 inch 2020 Meta is legal. A 34 inch is legal. The bat in your hands can be legal or illegal based on one inch of length, and the stamp printed on the barrel is identical either way. This is the single clearest demonstration in the sport of why the stamp is not the final word; the list is.
The used market keeps this relevant. Decertified 33 inch Metas circulate on resale sites at attractive prices, sometimes listed innocently and sometimes not. If you are shopping used BBCOR bats, the model number matters: BBMTB3-20 in the 33 inch is the banned one. An umpire who knows bats will spot it, and the penalty lands on the player, not the seller.
For the record, the Meta story did not end in 2020, and its aftermath explains modern BBCOR skepticism. Louisville Slugger offered affected owners a resolution process, retailers pulled the 33 inch from shelves, and the following season's Meta returned redesigned and fully certified. The episode joined a small but instructive list of BBCOR decerts, alongside the 33 inch Stinger Missile II in 2022 and older names like the Marucci CAT 5 squared and Reebok TLS, all of which share the Meta's defining trait: the ban attached to specific lengths or models, not the whole family name. That pattern is why every serious bat check is a model number check, not a brand check.
The Bottom Line
Check the length before anything else. The 33 inch 2020 Meta is banned in high school and college play permanently; every other length is legal. On the used market, treat a cheap 33 inch Meta as exactly what it is.

Frequently Asked Questions
Compliance testing at the WSU Sports Science Lab found the 33 inch model exceeded the BBCOR .50 performance limit after break-in. The decertification took effect February 21, 2020 for NCAA play, and high school play under NFHS rules followed the same list.
Yes. Only the 33 inch versions (standard, GLD, and Custom) were decertified. All other lengths of the 2020 Meta remained on the approved BBCOR list and are legal in NFHS and NCAA play.
Not in any league that requires BBCOR certification, which is what the bat was built for. Some recreational or adult leagues without certification requirements might not care, but for high school and college play the 33 inch is permanently illegal.
Retire it from certified play; it is permanently illegal wherever BBCOR is required. It remains a usable batting practice bat. If you bought it new during the original window, Louisville Slugger ran a resolution process, though that window has long closed. Do not resell it as game legal; listings that hide the decert do get flagged, and the buyer's player pays the price at the plate.
