Yes. See the list Len posted. Keep in mind this is just the banned list. Need to read what other items are checked by the umpires. Example if the end cap looks like it has been altered your bat is banned for that tourney. We had a bat banned because the ASA stamp had worn and you could not read it, even though the same bat was being used by a different girl and you could read the ASA stamp. The older Rip It's are bad about the ASA stamp wearing off. We had a CF4 banned last year due to a deep scratch, looked like the fence got it.
