Can’t anybody play this game? In pro baseball, most hitters will tell you they usually don’t want to know whether a teammate thinks he’s stolen the catcher’s sign for the next pitch. Not only is there a risk that the filched signal is wrong, but the input adds complexity to an already daunting task. Hitters may make an educated guess on what pitch might come, but their main job is to attempt a disciplined reaction, spoiling or avoiding great pitches, and pouncing on mistakes.
