The Abbreviations for Baseball Positions

The Abbreviations for Baseball Positions

When watching baseball, a beginner might be confused by the letters next to a player's name. Letters like P, 1B, LF, C, are commonplace in baseball but it might be daunting for a beginner to know what they mean. In order to understand where people play and expertly understand statistics, you must first know what the positional abbreviations are and what they mean.

What are the infield abbreviations?

In baseball, the infield is the four positions played near the bases. They are the first line of defense for any batted ball and play an important role on most plays. The defensive positions that involve the bases are first base, second base, shortstop and third base. The infield, abbreviated IF, consists of these four positions:

  • 1B​ - The abbreviation for the first baseman, who plays near first, is 1B
  • 2B​ - The abbreviation for second base, who plays near second, is 2B
  • 3B​ - The abbreviation for third base, who plays near third is 3B.
  • SS​ - The abbreviation for shortstop, which lines up between second base and third base, is SS.

The responsibilities of these positions include catching balls that are hit by the batter and catching balls that are thrown by other fielders.

Pitcher

The pitcher is the position that starts every play by throwing the ball to the batter. The abbreviation for the pitcher is simply P. The pitcher's other main responsibility is to field any balls near the center of the baseball diamond. The pitcher position can also be broken down into two abbreviations: SP and RP.

  • SP -​ SP stands for Starting Pitcher or the pitcher that starts the game
  • RP -​ RP stands for Relief Pitcher or the pitcher that replaces the starting pitcher or other relief pitchers

Catcher

The catcher is another defensive position and is also the only one of its kind in the game. ​The abbreviation for the catcher is simply C​. The catcher has to catch, or at the very least block, all pitches from the pitcher or hits and pop-ups from the batter in the vicinity of the catcher's position, which is just behind home plate in foul territory; the catcher also occasionally can throw out an opposing team's base runner who is trying to steal a base. Catchers also give signals to the pitcher for what kind of pitch to make.

Outfield

In baseball the outfield, abbreviated OF, consists of three regions. These regions are center field, left field and right field. The responsibility of the outfielders is to catch or chase down any balls that are hit by the batter into the outfield and make a return throw, if necessary, to a base or another infielder. The abbreviations for these positions are:

  • RF -​ RF stands for Right Fielder, the outfielder who plays on the right side of the field.
  • CF -​ CF stands for Center Fielder, the outfielder who plays in the middle of the outfield
  • LF -​ stands for Left Fielder, the outfielder who plays on the left side of the field.
