Although I don't know a lot about baseball, I would assume the players on the field who would be most important would be the pitcher and the catcher. And the reason I say that is because the pitcher and the catcher have to work together in order to get the batter out. The pitcher is the one who determines what throws he's going to be making in order, again, to get the guy out. But the catcher also works with him in order to be able to do that. I don't really know much about the rest of those on the field. I do know, though, that the pitcher and the catcher are the ones who are making that determination in order to get the guy out.
