What is po in baseball?

In baseball, "PO" stands for "Putout," which is a statistic credited to a defensive player who records an out by tagging a baserunner, catching a batted ball, or assisting in a putout. Putouts are recorded for various defensive plays, including catching fly balls, fielding ground balls, and tagging out runners attempting to advance to a base.

Putouts are an important defensive statistic in baseball, as they reflect a player's ability to make plays and contribute to the team's overall success on the field. The number of putouts a player has accumulated throughout the season is often used to assess their defensive performance and value to the team.
