NCAA decertifies a Marucci bat

Until further notice, the 33-inch Marucci 2011 Cat 5 Squared adult baseball bat has been decertified by both the National Collegiate Athletic Association (NCAA) and the National Federation of State High School Associations (NFSH). As a result, the 33-inch Marucci Cat 5 Squared is a non-compliant bat with leagues that adhere to NCAA or NFSH rules, which includes American Legion Baseball.

The elimination of this bat during competition is effective immediately as the NCAA has found, during testing, that it does not meet the BBCOR (Batted Ball Coefficient of Restitution) Bat Standard.

Because the decertification only affects the 33-inch model of the Marucci Cat 5 Squared, customers can contact Marucci to return their decertified bat. For information on how to return the bat, visit
