Add up the cost of all the wood bats you would break in batting practice and games and the price of an aluminum bat doesn’t seem so bad. The BESR standard could be changed to address safety and the impacts on the game but don’t expect the bat manufacturer’s to do this on their own. They are just responding to the market. The change would have to be mandated by the sanctioning bodies. This problem and the solutions are completely in the hands of baseball people.
