So I went to use my wood bat in league the other day and the umpire asked if it had the new thumbprint stamp on it and I said no. The umpire told me I could not use it because it did not have the new stamp. After the inning was over I pulled up the new bat rules on my phone from the USSSA web site and the rules state the all bats must have the new USSSA stamp OR be a wood bat. The umpire told me that those are not the correct rules and asked where I found those rules. Then was basically telling me that I must have wrote up the pdf that the rules are on. The bat I was going to swing was a Louisville Slugger wood bat. It did have an ASA stamp but not a USSSA stamp
