Quick Take
The 2017 CF Zen Drop 8 (2 5/8) and Drop 10 (2 3/4) USSSA bats were deemed illegal for excessive performance. Re-tooled versions with orange end caps were introduced to meet compliance, but the original models remain highly sought after for their unrivaled power.
Here are the illegal DeMarini CF Zens:
- 2017 Green/White Drop 8 2 5/8 USSSA
- 2017 Blue/White Drop 10 2 3/4 USSSA
- 2017 Custom and Zero Dark Designs in the Above Sizing

What CF Zens Are Illegal?
2017 CF Zen
The CF Zen for 2017 (the blue one pictured below) is illegal in USSSA play. That is the 2 3/4 drop 10. As well, the 2017 CF Zen in a 2 5/8 with a drop 8 (that is a green/white version pictured below) is also illegal.
DeMarini made new versions of these bats that have an orange end cap and a new serial number. Those re-tooled versions of the bat are legal.
2017 DeMarini CF Zen 2 3/4 Illegal
2017 DeMarini CF Zen 2 5/8 Drop 8 Illegal
2018 CF Zen
Not Illegal (Any Longer):
Although the 2018 versions were briefly banned, USSSA came to their senses. The 2018 version of the bat (the red and white one) is perfectly legal.
2019 CF Zen
Never Illegal:
The 2019 USSSA CF Zen versions of the bat are perfectly legal in all lengths and sizes. DeMarini’s 2019 CF Zens split their serial numbers between the shorter and longer bats. This method, learned the hard way, works as a fail-safe in the event the USSSA has another seizure.
The 2018 CF Zen (white/red) was briefly banned by USSSA. However, after further review, it was reinstated.
Later, in 2017, DeMarini re-released the above bats in retooled versions. These bats are noticeable because they have an orange cap on the end and an orange stamp on the barrel.
Where to buy the Banned Versions
The banned 2017 versions are tough to come by. And expect to pay a lot.
Every so often, one pops up on Amazon with a search like this. Make sure it does NOT have the orange end cap (that is the retooled one). The ratings are usually terrible because the bat has some durability issues. But make no mistake: The banned CF Zens are illegal because they are earth-burning hot. (They make our best youth bats ever for a reason.)
Otherwise, your best bet is eBay. Try both this search and this search. These bats usually run a MASSIVE premium.
Most of the 2 5/8 drop 8’s were remade into the 2018 version of the CF Zen (the red/white one).
2017 Retooled CF Zen
We have hit with this bat in the cage and at a few different games among different players. It is definitely not the bat of old. That thing made tiny little kids look like rock stars. The retooled one is nice and performs like other bats in this age category should, but the fact it is dialed down from the old (illegal) one makes us a tiny bit disappointed. That is not to say the Retooled Zen is a bad bat. Indeed, we like it. Just note you won’t be seeing the bombs that made this bat illegal. And, to boot, the bat weighs about an ounce more than it used to.

Word spreads fast on the internet. So when DeMarini’s 2 3/4 drop 10 CF Zen for 2017 was deemed illegal by USSSA on a Thursday night while we were enjoying some Spring Training games, our social media and email blew up with requests for information on what exactly that meant. Since we have now had time to get back in the saddle, much of the initial panic in the market has worn off. Still, we detail the information we have gathered about the CF Zen Illegal Article Contents.
What CF Zen is Illegal
The CF Zen is the second-largest bat line in the world. It comes in several iterations, including a BBCOR, 2 5/8, and 2 1/4, in addition to the 2 3/4. Within the 2 3/4 “big barrel” section, the bat comes in a drop 10 and drop 11. Do note that the drop 11 is considered a Junior Big Barrel and only comes in short sizes.
- 2017: The 2 3/4 Drop 10 Big Barrel version and the 2 5/8 Drop 8 of the CF Zen have been removed from the USSSA certification list. There are several sizes in each of these—including a CF Zero Dark Thirty that is included.
What to Do with Your Illegal One?
At this point, you’ve missed the boat to exchange it. For some time, Demarini offered an exchange program but that ship has sailed.
We would suggest you sell it on eBay for a pretty penny.
Here is DeMarini’s Statement
“For the past two weeks, we have worked closely with USSSA to complete its audit of the 2017 CF Zen -10 2 ¾” and the 2017 CF Zen -8 2 5/8”. Based on complete and final audit findings and our unwavering commitment to providing players with the best, compliant bats in the game today. DeMarini has concluded its youth baseball bat BPF audit for USSSA and the following bats have been officially withdrawn from USSSA baseball play as a result of that audit.”
They then give the serial numbers of the bats we listed above. You can see that full statement here.
What To Do with My CF ZEN 2 3/4 Drop 10?

Easy. Sell it for a lot of money. Then, use the proceeds to fund your baseball season for a year or two.
Is DeMarini Bad?
Although the inability to produce quality control in manufacturing to ensure bats maintain a certain degree of integrity is troublesome, DeMarini made an illegal bat, which proves a couple of our working theories on this site.
- Bats do have different performances. Saying the BPF and BBCOR standard ensures every bat is the same doesn’t jive with the fact that even the most notable companies in the space struggle to get it up against the line. One bat is indeed better than another—some even too much so. They simply don’t make crappy bats illegal.
- Aggregated player reviews are generally correct regarding what bats are the hottest. We couldn’t even count how many times we were told how hot the 2 3/4 Zen was. People loved that bat despite it being the CF Zen Drop 10 2 3/4. Is it Illegal in my league? USSSA is the governing board for the 1.15 BPF stamp. As a 2 3/4 bat, this version of the Zen was only available for some leagues anyway. The question you need to solve is if the USSSA stamp certification is a requirement for the league you play in. If it is, you should not be able to use that CF Zen in your league. We would suggest you start the voucher process sooner rather than later. Other leagues don’t care what kind of bat you use, especially when you get into the leagues where this bat is appropriate, like bats for 8, 9, and 10-year-olds. But you will still need to determine if it is relevant for a kid to use the bat, even if it is not “illegal” in the league you play. Our general advice is that $349 spent on Wilson’s website is well spent.
