Umm not quite correct. If there is a serious
injury with a batted ball to any player, the umpires have been instructed to confisicate the bat and ball. That could be the first or third baseman charging on a bunt and getting hit with a line drive right down to one of the runners getting drilled on the basepaths (Think older age groups here). If a girl is a poor fielder or gets nailed by a ball that takes a bad hop, that is not a reason to confiscate a bat.
The TD or UIC is to inspect the bat to determine if it may have been tampered with. If they feel it has not, then it returned to the coach. If they feel it may have been, the TD/UIC will issue a receipt and the bat will be sent along with the ball to the NSA home office for further testing. The home office of the NSA will take it from there and the umpire, UIC, and TD are out of the equation at that point.
If it fails, the NSA does not assign liability to anyone. The NSA notifies the coach and player of the testing and they handle it from there.
The wording of this statement
"If it comes back you have tampered with the bat you are personally liable for any damages and pain and suffering" makes it out like the NSA is the one determining that. The NSA does not make that kind of decision as liability is something that a court would assign, not the NSA or it's directors.
I just wanted to make sure there is no misunderstanding about this.
And
rolling a bat it is considered altering the bat. Hard to detect to the naked eye, but when the end cap is off it is very detectable. Anything other than repetitive hitting is considered altering a bat from the original state it came from the factory in.
Just use it.
Technically if you do anything but hit balls with it you are breaking the rules.
And at I think any NSA tournaments now if a player gets hit by a batted ball (line drives back at pitcher) they can confiscate the bat and send it out for testing. If it comes back you have tampered with the bat you are personally liable for any damages and pain and suffering.
