The center fielder is the defensive player (specifically, an outfielder) who is in charge of fielding baseballs that are hit into center field. He covers everything from shallow center field to the outfield fence, and from left-center field to right-center field. Since his coverage is so large, center fielders must be fast runners (as do all outfielders). As a center fielder, your responsibilities are the following:
Since the outfield fence is typically the deepest/farthest distance from home plate, center fielders have a lot of ground to cover. They must be fast runners and have a strong throwing arm to be able to throw from the deepest part of the field to the bases.
If you look at outfielders standing in their positions, you will notice they do not all stand in a straight, horizontal line across the outfield. Instead, the center fielder usually stands deeper, or farther from home plate, than the other outfielders. This is because center field is usually the deepest part of the field, and center fielders must adjust themselves accordingly. Once again, it is important that center fielders are speedy runners and strong throwers because they cover so much ground and are far from the bases.
