True . . . if your league follows ASA rules, which specifically prohibit altered bats.
But it's almost like the sauce in bodybuilding: pretty much everyone uses.
You must play in a league with a bunch of shitheads. Anyone who uses painted/shaved etc. bats is a fucking dirtbag. It can literally kill a pitcher. I've played in state tournaments, against players who were actually paid to play, etc. but never would I think winning a game was worth injuring someone.
The advanced leagues are starting to require face masks and shin guards for pitchers, and that's with legal bats.
Now, if a league is open and doesn't follow ASA or USSSA, fine. But a lot of times those leagues are recreational, and using illegal bats is even worse.
Plus, if you (not YOU BB, just in general) can't hit bullets or bombs with legal Mikens, Synergys and the like, you should find a new game. The legal bats are advanced enough. I have a guy who I played with for 17 years who is an excellent defender get his face broken, and that was at third base.
