Baseball, a sport rich in tradition and history, has a unique way of identifying player positions on the field. Like a few other sports that use names or specific roles to describe player positions, baseball employs a numerical system. This system not only simplifies the recording of plays but also provides a universal language for describing defensive alignments.

What Are The Baseball Position Numbers?

In baseball, each position on the field is assigned a number, from 1 to 9. These numbers are primarily used for scoring and statistical purposes, such as noting the sequence of players involved in a play. Here is a breakdown of each position number:

#1 – Pitcher (P)

Positioned on the pitcher’s mound, the pitcher is the player who initiates the play by throwing the ball towards the catcher, aiming to strike out the batter or induce a defensive play. The pitcher is numbered 1.

#2 – Catcher (C)

Positioned behind home plate, the catcher catches pitches that are not hit and also plays a crucial role in strategizing and guiding pitchers. The catcher is designated as number 2.

#3 – First Baseman (1B)

The first baseman guards the first base and is responsible for fielding ground balls, catching throws from other infielders, and tagging first base for outs. This position is number 3.

#4 – Second Baseman (2B)

Located between the first and second bases, the second baseman covers the area to the right of second base and is often involved in double plays. They are assigned number 4.

#5 – Third Baseman (3B)

Playing near the third base, the third baseman fields balls hit down the third-base line and is often involved in force plays and tags at third base. They are number 5.

#6 – Shortstop (SS)

Positioned between second and third bases, the shortstop covers a large area and is key in fielding ground balls, especially those hit between the bases. The shortstop is number 6.

#7 – Left Fielder (LF)

The left fielder covers the left portion of the outfield. And is tasked with catching fly balls, fielding hits to left field, and backing up third base. This position is designated as number 7.

#8 – Center Fielder (CF)

Playing in the middle of the outfield, the center fielder has a significant amount of ground to cover. And is often considered the outfield captain. This position is number 8.

#9 – Right Fielder (RF)

The right fielder handles the right portion of the outfield. And is responsible for fielding balls hit to right field and backing up first base. They are assigned number 9.

The Scoring System

In scoring, these position numbers are used to record plays.

For example, a play recorded as “6-4-3” indicates a double play where the shortstop (6) fielded the ball and threw it to the second baseman (4) for one out, who then threw it to the first baseman (3) for another out.

Or another example, when a batter hits a fly ball that is caught by the center fielder. The play is recorded as an “F8” in the scorebook.


Understanding baseball position numbers enhances one’s appreciation of the game and its nuances. This numerical system simplifies and provides a clear and efficient method to record and analyze plays. Whether you are a new fan or a lifelong devotee, a grasp of these position numbers deepens your connection to the timeless sport of baseball.
