So, out of the nine baseball players on the field, I feel like the most important would be the catcher, because they sit on the outside of the field, behind the home plate, and they can see everything that's going on. So they're the player that can see what's behind the pitcher and what's going on on every plate, and they kind of get a more wide view of the field, so they can see a little more if someone's trying to steal a base or anything that happens. They have the viewpoint for the team.
