Pinch hitters are baseball players who are substituted for another player in the game. They are also known as SUBS or standins. SUBS is a 4-letter word for pinch hitters, while standins is an 8-letter word. Pinch hitters are usually used when the original player is injured or not performing well. They are expected to perform the same duties as the original player and often have to make quick decisions in order to help their team win the game.
