What does Cleanup mean in baseball?

A ‘Cleanup’ is the fourth batter in the lineup

In the game of baseball, ‘Cleanup’ is a term associated with the fourth batter in the lineup. This player is usually the strongest and most skilled hitter on the team.

With three bases that can be filled by others, the idea is for the first three players to get on base, setting the stage for the cleanup hitter. This player is essentially the team’s best chance of scoring runs.

Since the cleanup hitter has the highest potential for driving in runs, they often end up with the most RBIs (Runs Batted In) on the team. Hence, the term ‘Cleanup’ signifies the batter’s role in scoring the maximum number of runs for the team.
