It’s been a few years since I umpires NSA ball. My recollection of their rules...
- Throwing a bat, or any other equipment, purposely or in anger is unsportsmanlike and can result in a warning of ejection, depending on the severity.
- Carelessly discarding a bat, like slinging it after hitting the ball or having it slip from your hand is not a rule violation. There’s no penalty, unless...
- If a thrown bat interferes with a fielder making a play, then it’s interference, dead ball, batter is out.
