The infielders include the following players:
While the pitcher and the catcher are not typically considered fielders since their primary job is not to field the baseball, for the purpose of this tutorial we will include them with the infielders since they play in the infield.
First Basemen, Second Basemen, and Third Basemen
As we learned in Chapter 4: Baseball Player Positions, the first baseman occupies the area around first base, the second baseman does the same at second base, and the third baseman does the same at third base. They are responsible for fielding and catching baseballs around their designated area, and for putting out runners at their respective base. There are some exceptions to this general rule, however, as they can temporarily cover each other's bases as necessary in the middle of a play.
The shortstop is similar to the first baseman, second baseman, and third baseman, except he does not have a specific base to cover. He is stationed between second base and third base, and is instrumental in making double plays.
The pitcher is the defensive player who stands on the pitcher's mound and delivers special throws, called pitches, to the batter, who then tries to hit the baseball. For most of the game, he and the batter are at the center of the action.
