There was a note in the 2012 Rule Book, (1-3-2d Note) inferring that in 2015, non-wood bats would have tamper-evident protocol in place.  Since then, the time frame has disappeared from the book and the wording has been altered.  A question arose at a recent clinic if this 2015 deadline would be in effect.

The response from Indianapolis is: "We are unable to find the technology that is affordable to implement at the manufacturing level. Please tell your schools as long as the non-wood bats have BBCOR .50 on the barrel then they will be compliant."
