Top of page 2. Seems pretty clear to me.

The only trick is how to PROVE a bat has been altered by rolling.

CSI anyone?

Not perfect, but you can do the "paper test". Use a sheet of notebook paper and wrap it around the barrel of the bat. Slide it up and down while slowly turning the bat. You can feel the smallest of ripples. All bats will have some ripple or minor dents that can be felt using the method, but a rolled bats ripples will be uniform.

YMMV
