In baseball statistics, a putout (PO) is awarded to a defensive player who (generally while in secure possession of the ball) records an out by one of the following methods:

In a regulation nine-inning game, the winning team will always have a total of 27 putouts, as one putout is awarded for every defensive out made; this is one aspect of proving a box score.

While the abbreviation for putout is "PO", baseball scorekeeping typically records the specific manner in which an out was achieved, without explicitly noting which player is awarded the putout for common plays. For example, a strikeout is recorded without noting the putout by the catcher, with additional detail only provided as needed. For example, "Fryman struck out (catcher to first)" in a play-by-play summary in reference to an out recorded following an uncaught third strike, which indicates the putout was credited to the first baseman rather than the catcher.
