Pitching the third strikeout 

A strikeout occurs in a baseball game when the pitcher is unable to deliver the final strike to the batter. However, this is also termed the PO put out since the pitcher receives credit when they cut down the batter’s wicket. 

Catching The Flyout

A flyout occurs when the opposition team catches the ball and this can happen anywhere and anytime during a baseball game, depending on the pitcher, as well as how fast he hit the ball in the air. Once this is the case, the batter hands the opposition players the chance to get create credit and create a putout.


When The Base Has Been Identified For A Flyout

Who is Credited With The (PO) Putout?

The players that get most of the PO credits in a baseball game include the fielder, catcher, and first baseman. You can see how this is made possible by our explanation below.

1. Fielder

In baseball, the fielders are the players on the other team who are often responsible for defending the base and preventing the batter from moving into a running position. The fielder can accomplish this task with relative ease by recording an out. 


2. First baseman

The first baseman (1B) also gets the PO putout. Asides from being fielded in the first base, they can also be assigned to handling the area that is nearby. This is the case, although they are normally positioned nearest to the baserunners close to the fielder.

3. Catcher

The catcher is the third person who gets credits for the PO putout in a baseball game. He is the fielder that gets or catches the ball before it hits the ground thus making the player get the PO credit. 

It should also be known that the catcher is also one that gets the putout credit for every strikeout that is thrown by the pitcher. The only exception is when there is a dropped third strike.

Do Catchers Get (PO) Putouts In Baseball?

It appears that the answer is yes. Here are the scenarios:

  • If the catcher safely catches a pop-up.
  • If the catcher tags out a runner trying to score (or gets him by force-out, no tag is necessary)
  • If the catcher retires an offensive player while somewhere else on the field (for example, backing up first base, and the ball gets loose),

If any of the aforementioned situations occur, each of them will be credited as a putout for the catcher. It should be known that these plays exist although they are not been readily produced in recent times. 


Also, the catcher receives credit for the putout whenever he prevents a strike-three pitch from being delivered. The putout is awarded to him since he was the last defensive player to touch the ball. 

One notable instance from the past occurred on April 29th, 1986. Red Sox P Roger Clemens set the record for most strikeouts in a single game, whiffing 20 Mariners.

The Boston C Rich Gedman secured all 20, and he has been given credit for 20 putouts although he didn’t make any other plays that resulted in an out).

Why Is A Putout PO Important?

A putout is significant in baseball because it is the foundation upon which more intricate scoring maneuvers are built. It is of great use to the official scorer in determining the high points, outputs, and outcomes of the game for each of the teams participating in it. 

The scorer of a baseball game can generate a comprehensive report on the batter’s activities by using the PO or putout statistics. This report will cover the batter’s progression from being left on base to being scored or put out. 


When the scorer has finished putting the finishing touches on the report, he will finally be able to draw conclusions about a team’s plate appearances and demonstrate that this is equivalent to all of the moves the team earned throughout the game. 

Putouts are essential to the smooth progression of a baseball game, which is another reason why it’s necessary to keep track of them. 

It appears that it would be impossible for either team to win the game if there was no physical effort required to record an out.
