Bat Warmers
 

New rule from ASA for 2010. Bat warming sleeves are now allowed.

Rule 3, Section 7: Characteristics of approved equipment cannot be changed. Examples include icing or cooling of any equipment. In addition, approved bats shall not be rolled, shaved or modified to change their characteristics from that produced by the manufacturer. Warming sleeves on bats are now approved.
Comments: Changes the rules to allow warming sleeves used on bats and includes rolling or shaving of bats to be an illegal act.

Don't know about NCAA or USSSA. No mention of a change in NFHS per 2010 rule book.

Does anyone know of any updates for NCAA, NFHS, or USSSA?

I believe this was strictly an ASA move. Here are the rule changes for NCAA for the upcoming year.

I really like change #19 of NCAA rule changes being in writing. We have done that, but it helps having it written down for coaches

Yeah...it is nice to have some actual support on that issue.
