Step-by-step explanation:
A batter who is replaced by another batter is called a pinch hitter.
In baseball, a pinch hitter is a player who is substituted for the starting batter during an at-bat. This strategy is often used when the team wants a different hitter with specific skills or to exploit a favorable matchup against the opposing pitcher.
For example, let's say it's the ninth inning, and the team is losing by one run with two outs and runners in scoring position. The manager may decide to bring in a pinch hitter who performs well against the type of pitch the opposing pitcher throws or has a higher chance of hitting the ball to drive in a run.
