I built the free bat sizing calculator and legality checker on this site. This page is about decertified bats, the ones that were legal the day you bought them and are not legal anymore.
When I played, nobody owned a bat.
There was one bag. Four or five bats in it, all of them dinged up, most of the grips shot. One was huge and one was tiny and if you were lucky there was something in the middle. You grabbed whatever fit and you went up there.
Nobody checked those bats. Not the umpire, not the coach. There was nothing to check for. A bat was a bat.
That changed around twelve or thirteen. That’s when kids started showing up with their own. Which makes sense, because before that a kid is banging the bat off the concrete for fun, and no parent is spending real money on something headed for a curb.
Now the league emails you a link to a sporting goods store and tells you which certification to buy.
And a bat you bought that way, on the league’s own instructions, from a manufacturer the league approved, can come off the approved list two seasons later.
What decertification actually means
A bat gets tested before it goes on sale. It passes. It gets the stamp and goes on the approved list.
Then the governing body buys one off a store shelf and tests it again. This is called compliance testing, and USA Baseball runs it at the Washington State University Sports Science Lab using the same protocol as the original certification.
If the retail bat doesn’t match what got approved, the bat comes off the list.
That’s the part that catches people. Your bat still has the stamp on it. The stamp is permanent, it’s molded or printed into the barrel, and nobody is coming to your house to scrape it off. The bat looks exactly as legal as it did the day you bought it.
It just isn’t.
This is different from a bat that never had the right stamp in the first place. If you’re not sure which certification your league wants, start with the four stamps and which one goes where and come back here after.
The USA Baseball decertified bat list is one bat long
That’s not a typo. One bat, since the USABat standard started on January 1, 2018.
Easton Ghost X, 30 inch, 20 ounce, 2 5/8 inch barrel. SKUs YBB18GX10 and LL18GHX.
That’s the whole list.
Every other length and drop of the Ghost X stayed approved and is still legal today. Only the 30 inch came off.
The ban covers every league that adopted the USABat standard, which is most of youth rec baseball. Little League, Cal Ripken, Babe Ruth, PONY, Dixie Youth, Dixie Boys, AABC, and NABF.
Easton ran a return program for affected bats. If you still have one, USA Baseball lists Easton’s line at 1-844-531-7079 on their decertified bat page.
USSSA keeps a longer list
Travel ball runs on a different standard and a different list. USSSA calls theirs the Withdrawn and Non-Compliant Baseball Bat Models list, and it has a lot more on it.
| Manufacturer | Model | Sizes affected |
|---|---|---|
| Marucci | Cat5 MCB2 BBCOR | 33/30 |
| Nike | BT0636 CX2 light grey | not listed |
| DeMarini | 2017 CF Zen Balanced (-8) | 29/21, 30/22, 31/23, 32/24 |
| DeMarini | 2017 CF Zen SL 2¾” (-10) | 28/18, 29/19, 30/20, 31/21, 32/22 |
| DeMarini | 2017 CF Zen Zero Dark 2¾” (-10) | 29/19, 30/20 |
| DeMarini | Custom 2017 CF Zen 2¾” (-10) WTDCCBZ17V | all |
| DeMarini | Custom 2017 CF Zen Balanced (-8) WTDCCBR17V | all |
| Dirty South | Kamo BB KA 8 | 30/22, 31/21, 32/22, 31/23, 32/24 |
| Easton | Ghost X, USA marked | 30/20 |
Those numbers in the model names are drop weights. A -10 means the bat is ten ounces lighter than it is long. If that notation is new to you, here’s how bat drop works.
Look at that list again. Seven of those nine entries are DeMarini CF Zen.
The CF Zen was everywhere. It was on commercials. It was the bat kids asked for. And it got pulled apart size by size across three different versions of the same bat line.
The full list is on USSSA’s site.
One thing the two lists tell you at a glance. USSSA allows more performance than USABat does, and USSSA has pulled a lot more bats. That’s not a coincidence. Here’s how the two standards actually differ.
USSSA also picks up other people’s rulings automatically. Any BBCOR bat withdrawn by the NCAA or NFHS gets withdrawn by USSSA. Any USA Baseball stamped bat that USA Baseball pulls gets pulled by USSSA too.
So a bat can vanish from two lists on the same day with only one announcement.
The BBCOR one people remember
The Louisville Slugger 2020 Meta (-3).
Additional testing led the NCAA and NFHS to remove that specific model from their approved bat lists. It was the most popular BBCOR bat in the country when it happened, which is why high school parents still bring it up.
Worth knowing if your player is heading to high school: BBCOR is changing hands, and the marks on the barrel are changing with it. Here’s what happens in 2028 and 2029.
Why one size gets pulled and the rest don’t
This is the part that saves people money, so read it twice.
Each length of a bat is certified on its own. USA Baseball’s explanation is that individual lengths and drops are designed and produced slightly differently, so they get treated as separate designs and tested separately.
One length can fail while every other length in the same model family passes.
Which means a headline naming your bat’s model does not mean your bat is illegal. The Ghost X is the clearest example. The 30 inch came off the list. The 28, 29, 31, and 32 stayed on it.
Check the length and the weight before you do anything drastic.
How to check the bat in your garage
Four steps.
- Find the model name on the barrel
- Find the length and the weight, usually stamped near the taper or the knob
- Check the full decertified bat list, which merges all four organizations into one place
- Match all three: model, length, weight
Model alone is not enough. That’s the whole trick.
You can also check the current USABat approved list, which is the other direction. If your bat isn’t on the approved list, that’s your answer.
If the mark on the barrel is too worn to read, you have a different problem and the same outcome. An illegible stamp gets a bat pulled the same as no stamp. That usually shows up on a beat up hand-me-down, which is also where dents and cracks come into it.
Where decertified bats end up
eBay, mostly.
They show up listed as illegal, or not for league use, or some version of that. And they sell.
Here’s the sad part. When a popular bat gets banned, people want it more. The ban is the advertisement. A bat that was one of a hundred options becomes the one that hits too hard, and somebody is going to buy it for exactly that reason.
Which is why these things stay in circulation years after they came off the list.
If you’re buying used, this is the failure mode. The seller isn’t hiding anything. They said it right in the listing. The buyer just didn’t know what it meant.
Nobody is really checking, and that’s not the point
Let me be honest about enforcement.
Most rec umpires are volunteers. They want their pay and the game balls and they want the bases at the right distance. Checking two full rosters where every kid has a different bat is hard, and mostly it doesn’t happen.
So a parent could read all of this and figure their kid will never get caught.
Here’s why that’s the wrong way to think about it.
The velocity. The whole reason the standard exists is what comes off the barrel. A bat that performs above the limit sends the ball back faster than a kid at 46 feet can react to. God forbid it catches somebody in the face. That’s not a rules problem, that’s a hospital.
You’re measuring the bat, not your kid. If you actually want to know how good a hitter your player is, the bat has to be legal. Otherwise the numbers are telling you about the equipment.
You’ll always get a few parents who don’t care about either of those. You can spot them from a mile away. They’re the ones screaming at a volunteer umpire over a twelve year old’s baseball game, chasing any edge they can find, living through the kid instead of just enjoying watching him play.
Don’t be that. It’s a game.
Your bat got decertified. Now what?
Start with the manufacturer. Not the store.
The store sold you a bat that was on the approved list the day you bought it. They did nothing wrong and their return window closed a long time ago. The manufacturer is the one who marked that bat and said it met the standard.
When USA Baseball pulled the Ghost X 30/20, Easton ran a return program for it. That’s what it looks like when a company handles it.
Ask for a refund. Be specific. Give them the model, the length, the weight, and the date the bat came off the list.
If they don’t respond
File a complaint with your state attorney general’s consumer protection office. Every state has one, and you can find yours through the National Association of Attorneys General. That’s the complaint that tends to get a company to answer.
Put it on the Better Business Bureau too. There’s no enforcement behind it, but it’s public, and public gets returned calls.
A credit card chargeback is probably gone. Most issuers give you 60 to 120 days from purchase, and a bat that got pulled two seasons later is well outside that window.
I’m not a lawyer. This is what a parent can try.
The honest part
You might not get the money back.
That’s the part nobody tells you when you’re standing in the store. You bought the bat the league said to buy, from a manufacturer the league approved, and the bill for their mistake lands on you.
Where this actually belongs
On the league.
The league approved the manufacturer. The league takes the sanctioning money. When a bat fails the league’s own standard, the family that bought it in good faith is the one holding it.
Leagues could pressure manufacturers to make families whole. They could drop a manufacturer that puts a non-compliant bat on the market. Mostly they post a notice and move on.
That’s my two cents, not a rule.
Common questions
Is my bat still legal for the rest of the season if it gets decertified mid-year? No. USA Baseball’s position is that a decertified bat comes out of play immediately, not at the end of the season. Their reasoning is that letting non-compliant bats finish out a year makes the standard meaningless.
How do I find out my bat got pulled? Does anyone tell me? Not directly. Your coach is usually who tells you, because leagues push the notice down to coaches. After that it’s the official lists. If your league doesn’t post it and your coach doesn’t know, call the league office.
My league doesn’t check bats. Does it matter? Yes, for the safety reason above. Also, some leagues do check at tournament time even when they never check during the season, and that’s a bad moment to find out.
Does a decertified bat lose all its value? Close to it, if you’re honest in the listing. And you should be honest in the listing. A bat sold without disclosure is a problem you handed to another family.
Can I still use it for practice? Nothing stops you physically. It’s not going to teach you much, since you’d be training on feedback you’ll never get in a game.
What should I buy to replace it? Get the size right before you shop the model. Run the sizing calculator for your player’s height and weight, then confirm the certification your league requires before you spend anything.
Where does this information come from? USA Baseball’s decertified bat list, USSSA’s withdrawn and non-compliant bat list, the USABat approved list, and Little League’s bat information page. Lists change. Check them yourself before you spend money.
