ALL Miken bats are banned in all Burlington Recreation Department Leagues.  In addition, any bat that is not ASA certified is also banned.  Please note, that just because a bat holds an ASA certification, does not make it legal for our leagues.  A list of bats that had previously been ASA certified, but have since been deemed banned can be found here: http://usa.asasoftball.com/e/build_batlist_one_page.asp
