These are words you don't want to see associated with your favorite bat. Baseball and softball leagues have bat standards set by governing bodies that dictate what bats are acceptable for use. To become certified, bats must pass tests conducted by independent labs, which is what BBCOR Certification and USABat Standard use. When a bat passes the independent test, the bat manufacturer is notified, and the corresponding certification stamp can be placed on the bat.
And when a bat doesn't pass? That's when the bats are deemed illegal or banned.
It is possible (and has happened) where a bat passes these tests, but fails a random test given by the governing body of the League. When method is employed, the governing body officials resubmit the bat to the independent labs for further testing. In this scenario, the bat is then "decertified". This happened to the DeMarini CF Zen in early 2017.
Best Illegal Bats Of All-Time
Based on talks with officials, vendors, coaches, and customers, here are JustBats.com's five (5) best illegal bats and banned bats, as well as their most similar approved bat.
DeMarini CF Zen
In April 2017, the bat industry was suprised to hear that eleven (11) Demarini CF Zen youth bat models did not pass the BPF audit; thus, deeming these bats officially removed from USSSA certification. The ruling affected the drop 8 and drop 10 versions of the CF Zen, which cost DeMarini half their youth baseball bat lineup. Plus, DeMarini, in a goodwill effort, had to issue vouchers to upset customers. Initial reviews of the bats suggest that the DeMarini CF Zen contained a little too much pop for the youth field.

Shortly after the BPF audit decision, Demarini released the 2017 DeMarini CF Zen Re-Tooled (DXCBZR). The differences between the original CF Zen that this model carries the USSSA BPF certification, contains an orange "R" to indicate it's the re-tooled model, and, of course, less pop.
Marucci CAT 5 BBCOR
Marucci was already on the proverbial map, but the CAT series put the bat company in a whole new stratosphere. Admittedly, the Marucci CAT 5 BBCOR bats (MCB2) weren't all banned, just the 33 inch and 34 inch models. The reason for the decertification was because the CAT 5 made any player a homerun threat. The bats were hotter than the sun's surface and it didn't take long for the governing bodies to notice.
Comparable approved bat for the Marucci CAT 5 BBCOR
Already one of the most popular BBCOR bats in JustBats.com history, the Marucci CAT 7 BBCOR baseball bat (MCBC7) continues an impressive lineage of the CAT series. Besides being BBCOR certified, this one-piece alloy constructed bat has optimized barrel design, no dead spots, and the AV2 knob minimizes negative vibration on swing.
While the Easton Stealth caused BBCOR, the RIP-IT Prototype BBCOR bat (B1403) attempted to break the rule. Deemed too hot by the NCAA, the Prototype was de-certified in July 2011. RIP-IT released the Prototype II (PROB2), which was approved by the NCAA, and RIP-IT was able to get the original Prototype re-listed. However, after the initial de-certification, many Leagues opted not to allow the bat.
Comparable approved bat for the RIP-IT Prototype
Unlike the other banned bats, there is no great comp for the original RIP-IT Prototype. With the BBCOR Certification established, it will be difficult for a bat to be created with the same explosiveness as the Prototype had.
COMBAT B2 Youth
71 five-star product customer reviews. The COMBAT B2 Composite Youth Baseball Bat (B2YB1 - 12) was nicknamed "Da Bomb" and lived up to its name. Balls exploded off this bat, in large part due to COMBAT's enhanced sweet spot and a balanced design that turned any Little Leaguer into a blue-chip prospect. In 2011, it didn't take long for Little League officials to change course on the bat's certification.
Comparable approved bat for the COMBAT B2 Youth
Roaring onto the baseball scene since its debut, the Easton MAKO BEAST (YB17MK12) will also be banned from USA Baseball Leagues starting in 2018. But, with its massive sweet spot, swing speed, and superb construction, the BEAST is about as close a youth bat will get to the COMBAT B2 until USABat Standard is in place.
Louisville Slugger oneX Fastpitch
Back in 2013, Louisville Slugger rolled out the oneX softball bats. Unfortunately, the bats weren't available for too long. A manufacturing defect caused cracking--and, in some instances, complete breakage--between the barrel and handle, which actually resulted in 170+ incident reports. Louisville Slugger quickly removed the bats and eventually introduced the most popular fastpitch bat: Louisville Slugger Xeno.
Comparable approved bat for the Louisville Slugger oneX
As a nod to its predecessor, the Louisville Slugger XENO Fastpitch softball bat (FPXN170) is actually oneX spelled backwards. This model comes intact with Performance PLUS Composite with zero friction double wall design. Essentially, Louisville Slugger enhanced the oneX's flaw and made a better fastpitch bat for all.
