Illegal Bat Lists | Easton Ghost X, Dirty South KAMO, DeMarini Zen

December 2, 2020 | by | @BatDigest

Perfect Game Bat Bans 2021
Starting in 2021, Perfect game bans all the USSSA banned bats, see below, and the 2017 DeMarini CF drop 5, the 2016 USSSA CF8 line of bats (5, 8, 10), the 2015 CF7 in a drop 5 and the 2015 Eaton XL1 in a drop 5. All banned for Perfect Game starting 2021.
NCAA 2020 Meta
As of 2/21, the 2020 Lousiville Slugger Meta in a 33-inch has been decertified (made illegal) for NCAA play.
High School (NFHS) 2020 Meta
On 3/2/2020, the 2020 Meta Prime in a 33-inch is also illegal for play in NFHS. That is, the 33-Meta is illegal in high school too. The 2019 version of the bat (the red one) is still legal in both NFHS and NCAA—we confirmed this directly from Slugger and the NFHS rules. Even more, proof we were right when we named that bat the best BBCOR bat for 2020.

If you need to return your 33-inch (Blue) 2020 Meta, here is Slugger’s process.

*The 2017 CF Zen USSSA lost its 1.15 certification in all sizes and lengths of the drop 10 2 3/4 and drop 8. This is the Blue/White 2 3/4 as well as the drop 8 Green/White one. As well, the bats zero dark thirty and custom versions are also decertified. Serial numbers that start with: WTDXCBR & WTDXCBZ.

**The 2018 CF ZEN USSSA lost its 1.15 certification, then gained it, then lost it, then gained it. As of 6/6/2018, the bats are LEGAL for play. And, although it is hard to believe, we think this one is here to stay. See DeMarini’s commentary here.

***The DSB KAMO lost its 1.15 certification in the 31 and 32 drop 10 (so 31/21 & 32/22) as well as the 30, 31, and 32 drop 8 (30/22, 31/23, 32/24).

Illegal 2019 Bats

For 2019 (as of April), there have been no high profile bats made unlawful. We don’t know of any low profile ones either.

There are still plenty of 2017 Zens with the white cap floating around.

DeMarini 2018 CF Zen: LEGAL

Updated: 6/6/2018

2018 CF Zen Illegal Bats List

Find this bat in Stock

After a huge amount of clamor, USSSA decided that the 2018 CF Zen is now re-LEGAL for play. They are removed from the banned list. We have updated the information below. You can find insight/return information via DeMarini here.

Updated 6/6/2018

After their first further consideration, all sizes in the CBZ drop 10 DeMarini 2018 CF Zen are LEGAL for play.

Updated: 5/4/2018

USSSA adds the 28, 29, and 30-inch 2018 CF Zen to the banned list, including the 31 and 32 of the same bat. They also clarify the 2018 Ghost X USA will NOT be allowed in USSSA games.

2018 Easton USA Ghost X 30/20: NOT LEGAL

Updated: 5/3/2018

USA Baseball decertified (made illegal) the USA Easton Ghost X bat in a 30-inch drop 10 in the 30/20 on 5/3/2018.

From what we’ve read on social media, Easton is offering a $500 voucher on their website for the return of a legitimately purchased USA Ghost X.

Return questions via Easton can be directed to Easton via email at or 1-844-531-7079.

More information can be found on USA bats decertified bats page.

Dirty South Bats KAMO: NOT LEGAL


The USSSA announced on 4/12/2018 at 4 pm PST that the Dirty South KAMO with serial number BB KA 8 is illegal for play in the following sizes: two drop 10’s and three drop 8’s (30/22 31/21 32/22 31/23 32/24).

The DSB KAMO (BB KA 8) has been withdrawn from USSSA play. This means, in not so many words, the bat is now banned for play. This includes the 30/22 31/21 32/22 31/23 32/24.

All the people saying Dirty South bats were hot were, clearly, right. A little too much so.

We are sure it is a massive headache to deal with, but they might take some solace in knowing they are in good company for what it’s worth. They don’t make crappy bats illegal. (See our DSB Made USA Bat Review. This one is perfectly legal). And, we should note, several of the KAMO’s are still permitted.

Are they (DSB) going to be able to withstand the capital and inventory issues associated with getting a marquee bat of theirs recalled? If they can, expect them to get a long term bump (akin to Anderson and the Techzilla).

These bats are the banned KAMOs (including three drop 8’s and two drop 10’s).

2017 DeMarini CF Zen Banning

With the recent, and rather high profile, “temporary” decertification of the 2 3/4 DeMarini CF Zen drop 10, we wondered what other bats have been de-certified over the years. It is not easy to find such a list. Likely, we have decided, because there have not been many baseball bats over the years that have been banned. Slowpitch softball has seen the worst offenders—with at least a dozen bats getting banned over the years. In the baseball space, we have found only three in the last, five and we have yet to find a fastpitch bat to get the boot.

CF Zen Illegal

Find This in Stock

Illegal Bat List Sources

A couple of sites had a good list of softball bats that have been banned over the years. It does not look to be updated very recently but was useful nonetheless. As well, SFsoftball has a similar list.

On the baseball side, one league site has at least some information on what bats are banned. The Texas Association of Sports Officials appears to be keeping at least some tabs on what bats are illegal.

Although it does not tell you what bats are decertified, the WSU site tells you what bats may have been initially certified.

De-certification Processes

To become certified, a bat must pass a particular standard set by the governing body. An independent sports science lab performs these tests at a major university. If the bat passes, then it is eligible to carry the stamping of the association.

However, throughout the year, governing bodies randomly test bats. Picture it much like random drug testing at the Olympics. These governing bodies can buy the bats directly on the shelf or take them from tournaments directly. They are sent to the lab and then tested.

If a bat does not pass, it is removed from play and becomes “decertified.”

Illegal Baseball Bats

Although likely others, we can find three bats that have lost their certification over the last few years in the baseball space. They include the CF ZEN 2 3/4 Drop 10, the Marucci CAT 5-squared in 32 and 33 BBCOR, and the Reebok TLS. Those three lost their certification in both high school and collegiate play. The Marucci Black 33 and 34-inch bat lost its accreditation for NCAA play only.

Mattingly Balistk

Illegal BAt list

Trying to make a play on the scene, the Mattingly brand of bats produced a super hot stick in the Balistk. Apparently, too hot. Mattingly bats never quite took hold, and, as of today, they’ve yet to produce a new bat in years.

Nike CX2

Illegal bat lists

A few years back, Nike made a serious run at the baseball bat space. However, the CX2 losing its certification appeared to mark the beginning of the end for the Nike Bat experiment.

Find one on eBay.

Louisville Slugger’s TPX Dynasty 2012

Illegal Bat Lists

Holding the distinct honor as the only drop 12 bats to lose its certification, Louisville Slugger’s 2012 Dynasty was one of the very first BPF bats to be banned.

Find one on eBay.

CF ZEN 2 3/4 Drop 10

CF Zen Illegal

As the only non-BBCOR bat on the list, the CF ZEN 2 3/4 was a dynamite bat that people raved about. It did have some durability concerns, but people still bought the bat in droves as it gave little Timmy’s across the universe chances to hit it into the stratosphere.

CAT 5^2 BBCOR 33 and 34

Illegal BAt Lists

The CAT 5^2 (5-Squared) in BBCOR was a beastly bomb dropper known for killing balls. It put Marucci on the map but also got de-certified after folks found it too hot to handle. But, it’s still legal in a 32 and it is a AMAZING.

Find one on eBay.

Reebok TLS

Illegal BAt list

Most were not aware Reebok made a baseball bat. Indeed, the TLS was legit. But it became decertified, and Reebok never quite recovered in the bat space. The BBCOR 33 inch was banned in both high school and collegiate play.

Find a Reebok TLS on eBay.

Marucci Black

Illegal Bats List

The Marucci Black bat has the distinct honor of getting banned by the NCAA but not by the NFHS. That is, the college said you’re out while high school told you’re safe. A strange turn of events and we don’t quite follow how that could happen, considering both leagues use the same standard. Nonetheless, there it is.

Find one on eBay.

Illegal Softball Bats

The list of unlawful softball bats is longer than we care to write about. Or, frankly, you should care to read about. As an example, let us picture the ASA bats that have been decertified up until 2014 only.
