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",[1] 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.
Note: entering the 2023 season, Joey Votto has the most putouts among active MLB players, with 14,440.
