no hands touching face for signs/signals, no spitting tobacco or seeds, pitchers can keep a wet rag instead of licking their fingers, no throwing the ball around the horn, and no bat boys/girls
They are going to have to reprogram a lot of robots to get compliance with all of that. Sounds like the ball will be thrown out after every use which is not new but no throwing around the horn makes little sense because it may be handled by several players before a play is over. No bat boys/girls means MLBPA will be demanding extra wages for having players doing demeaning duties.
