A PO is a putout, a term used to describe when a fielder is directly responsible for completing an out. This can be stepping on the base for a force out, catching a batted ball during a play, tagging a runner, or catching a third strike. 

KEY
POINTS
  • PO stands for Putout and is credited to a fielder who has directly recorded an out.
  • Common ways to get put out in baseball include touching a base before the batter or runner reaches it on a force play, tagging a runner, catching a hit ball, and catching third strike.
  • Fielders can receive unassisted putouts by stepping on bases during forceouts or tag runners while catchers usually get PO credits when they catch pitches that result in strikeouts. First basemen also receive throws from ground balls outs for credit of POs.

  • Jake Beckley holds the MLB record for most POs with 23767 from 20857 innings as first baseman playing for St Louis Whites

What does it stand for?

PO stands for putout. A putout is credited to a fielder who has directly recorded the out. The reasons include the common acts of stepping on base and catching a batted ball, as mentioned above, and when the umpires deem a fielder to be closest to a runner called out for interference. 

The players with the highest output totals tend to be catchers who catch a pitch that results in a strikeout and the first baseman who catches a throw from a ground ball out.

Common ways to get put out in baseball

The most common ways to get Put Out in baseball include touching a base before the batter or runner reaches it on a force play, tagging a runner, catching a hit ball, and catching a third strike. A fielder can also be given a putout if he is closest to when interference is balled. 

Who gets the putout credit?

Different players can get a PO credit. 

Let’s start with a fielder. This defensive player can record a putout after catching a hit ball. Fielders can also get an unassisted putout, where they step on a base during a forceout or tag a runner.

A catcher can also get a PO credit, usually when they catch pitches that are strikeouts. Catchers and first basemen are the two positions that tally up the highest PO score in baseball. A first baseman receives throws on ground ball outs to be credited with a putout.

Difference between an assist and a PO in baseball

An assist is an act where a fielder contributes to the batter or runner being called out. Usually, this is when a fielder throws the ball to another fielder who gets the putout. So, an assist is given to the act that leads to the out, but the player who directly causes the out is given a PO.

A fielder will get an assist if the out is not recorded due to an error, where a shortstop throws to the first batman, and he drops the ball. An assist is also given if the ball deflects off a fielder and a putout follows. Pitchers do not get assists on strikeouts.

However, a fielder will not get an assist if they make a wild throw, and a runner tries to advance but is putout.
