Definition: PO in baseball stands for Putout. A putout is awarded to the defensive player who directly records an out. Examples include catching a fly ball, catching a third strike, tagging a runner, or touching a base before a runner arrives on a force play. Putouts are one of baseball’s official defensive statistics and are commonly listed in box scores and player fielding records.
If you’ve ever looked at a baseball box score, player statistics, or scorecard, you’ve probably come across the abbreviation “PO.” Whether you’re a new fan, a fantasy baseball player, or someone learning how baseball statistics work, it’s natural to wonder: What does PO mean in baseball?
The answer is simple but important. PO stands for “Putout,” one of the most fundamental defensive statistics in baseball. A putout is credited to the defensive player who records an out directly, such as catching a fly ball, tagging a runner, or stepping on a base to complete a force out.
Although it may seem like a basic statistic, putouts play a major role in evaluating defensive performance and understanding how fielders contribute during a game. Certain positions such as first basemen and catchers naturally accumulate far more putouts than others because of their responsibilities on the field.
In this complete guide, you’ll learn exactly what PO means in baseball, how putouts are recorded, examples of different types of putouts, how PO compares to other defensive statistics, common misconceptions, practical tips for reading baseball stats, and answers to frequently asked questions.
Here’s a quick overview:
| Abbreviation | Meaning | What It Measures |
| PO | Putout | Defensive outs recorded directly by a player |
| A | Assist | Helping another player complete an out |
| E | Error | Defensive mistake allowing advancement |
| DP | Double Play | Two outs on one continuous play |
| FPCT | Fielding Percentage | Overall defensive efficiency |
Unlike offensive statistics such as batting average or home runs, PO measures defensive contributions.
Origin
The statistic Putout (PO) has existed almost as long as organized baseball scoring itself.
In the mid-to-late 1800s, official scorers began recording defensive plays to better evaluate players’ fielding abilities. Along with assists and errors, putouts became one of the three core defensive statistics used to summarize a player’s performance.
As baseball evolved and official scorekeeping became standardized, PO remained an essential part of every box score and scorebook. Today, Major League Baseball (MLB), college baseball, high school leagues, and youth organizations all use putouts as a standard defensive statistic.
Because every out in baseball must ultimately be completed by a defensive player, putouts remain one of the sport’s most fundamental metrics.
Popularity
Although casual fans often focus on batting statistics, PO is widely used by:
- Baseball coaches
- Scouts
- Statisticians
- Broadcasters
- Fantasy baseball players
- Sports journalists
- Official scorers
You’ll commonly see PO listed in:
- Box scores
- Player stat pages
- Defensive leaderboards
- Baseball scorecards
- Team statistics
- Historical records
Learning what PO means makes it much easier to understand defensive performance and follow baseball statistics more confidently.
How It Is Used
A putout is credited whenever a defensive player is directly responsible for recording an out.
Catching a Fly Ball
This is one of the most common putouts.
Example:
A center fielder catches a fly ball before it touches the ground.
Result:
- Center fielder receives 1 PO.
Force Outs
A first baseman frequently records putouts.
Example:
The shortstop throws to first base after fielding a ground ball.
Result:
- Shortstop receives 1 assist (A).
- First baseman receives 1 putout (PO).
Catching a Third Strike
Catchers receive putouts when they catch a third strike without the batter reaching first safely.
Example:
The pitcher throws strike three.
The catcher catches it cleanly.
Result:
- Catcher earns 1 PO.
Tagging a Runner
If a fielder tags a runner before they reach the base safely:
Result:
- The player making the tag receives the putout.
Stepping on a Base
During force plays, simply touching the base before the runner arrives records the out.
Example:
A second baseman steps on second base to force out the runner.
Result:
- Second baseman receives 1 PO.

Common Mistakes
Many new baseball fans misunderstand PO.
Thinking Every Defensive Player Gets a Putout
Only the player who directly completes the out receives the putout.
Other players may receive assists.
Confusing Putouts with Assists
Example:
Ground ball.
Shortstop fields it.
Throws to first.
Result:
- Shortstop = Assist
- First baseman = Putout
The throw itself does not earn the putout.
Comparing Putouts Across All Positions
First basemen and catchers naturally accumulate more putouts than outfielders or shortstops because of the nature of their defensive roles.
Raw PO totals should always be considered alongside player position.
Ignoring Other Defensive Metrics
Putouts are important but don’t tell the whole story.
Modern defensive evaluation also considers:
- Range
- Defensive Runs Saved (DRS)
- Outs Above Average (OAA)
- Assists
- Errors
- Fielding Percentage
Assuming More Putouts Always Mean Better Defense
A higher PO total often reflects position and opportunity rather than superior defensive skill alone.
