Use of a slow pitch bat in a fast pitch game

[shanning]

The bat had an ASA 2013 logo which by Rule 3 Section 1 is only to be used in Slow Pitch, Men's Adult Fast Pitch, Junior Olympic Boy's Fast Pitch and Men's Modified. This was JO girls fastpitch. Not sure if the term is illegal or not approved for JO girls or what.

I'm more interested in understanding if the safety issue of having a lower compression bat is something that would warrant, say ejection of the manager that allowed it. Maybe suspension of the manager if proved to be aware of the bat.

From what I understand, a lower compression bat (via shaving, rolling, or design ) can enhance the performance of the bat. That is the "cheating" aspect. But the safety aspect is that the unsafe BPF could cause a lack of response time from the defender (specifically pitcher at < 40' away) and a significant injury. After all, isn't that why USA Softball and USSSA do compression testing?
