BATS There have been requests for what bats will be legal and which bats are not. Rather than re-invent the wheel, we refer you to the ASA website.     Use this link to go to the ASA site for a list of APPROVED bats. Select "Bats" and click GO. On the next page, below 2004 and Beyond Approved Bats make sure "Bats" and "Display All" are selected. Click GO to see a list of all approved bats.   Other links on that page to non-approved bats.
