5 Best Illegal Bats Of All-Time

Illegal. Banned.

These are words you don't want to see associated with your favorite baseball bat or softball 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 USA Baseball Bat 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.

Louisville Slugger (Blue) Meta Baseball Bat

Comparable approved bat for the Louisville Slugger Meta

Fast forward to present day and the Meta continues to be one of the most popular composite baseball bats in the game. With available models in USA, USSSA, and BBCOR, baseball players of all skill levels continue to choose the big, composite barrel of the Louisville Slugger Meta baseball (and softball) bats.  

DeMarini CF Zen Youth Baseball Bat

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.

Marucci CAT 5 BBCOR Baseball Bat

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.

You've heard about the Marucci F5 baseball bat, right?

COMBAT B2 Youth Baseball Bat

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.

COMBAT baseball bats are now back. Read about what happened and what the future holds.

Louisville Slugger oneX Fastpitch Softball Bat

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 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.
