A pitcher in the context of baseball is an essential player who takes a position on the mound and delivers the ball to the batter. In Major League Baseball, specifically within the American League, the pitcher's role can be even more critical due to the designated hitter rule. Pitchers come in various types, such as starting pitchers, relief pitchers, and closer pitchers, each with unique responsibilities. Starting pitchers typically begin the game and aim to complete at least five innings, while relief pitchers enter the game later on, often to finish an inning or two. Closers are specialized relievers who usually come in during the late stages of a close game to secure a victory for their team. The pitcher's primary objective is to prevent the opposing team from scoring runs by striking out batters, inducing ground balls and fly outs, and picking off base runners. A pitcher's success is often measured by various statistics such as wins, losses, earned run average (ERA), strikeouts, and walks. As a part of Major League Baseball within the American League, the pitcher plays an integral role in determining the outcome of each game. The pitcher's ability to control the opposing team's offense can significantly impact their team's success throughout the season.
