Baseball Positions: All 9 Explained

The nine defensive positions, their numbers (1 through 9), where each player stands, and what they do. Here is the whole field at a glance.

The nine baseball positions and their numbers. Infield dirt in the middle, three outfielders across the back, and the battery (pitcher and catcher) up the center.

The 9 Baseball Positions by Number

Every position has a number from 1 to 9. Coaches and scorekeepers use the number instead of the name, so a ground ball from shortstop to first base is written 6 to 3, and the classic double play is 6 to 4 to 3.

Positions on the Field

The nine positions split into three groups:

  • The battery: the pitcher (1) and catcher (2), who start and receive every pitch.
  • The infield: first base (3), second base (4), third base (5), and shortstop (6), who handle ground balls and force plays.
  • The outfield: left field (7), center field (8), and right field (9), who track down fly balls and back up throws.
