Definition
A 'pinch hitter' is someone who substitutes for another player, typically in baseball, to improve the team's chances of success in a specific situation. More broadly, it can refer to anyone who steps in to fill a role or perform a task at short notice. The term implies adaptability and the ability to perform under pressure. Unlike a 'long-term replacement,' a pinch hitter is usually a temporary solution. Think of it as a quick fix or a backup plan. The goal is to provide an immediate boost or resolve a specific problem.
