The main objective of a baseball game is to score more runs than the opposing team. A run is scored when a player successfully navigates four bases, starting from home plate and returning back after hitting the baseball. Teams alternate between batting and fielding, with the batting team aiming to hit the ball and reach bases while the fielding team tries to prevent runs by getting batters out. Strategy plays a significant role, with decisions on when to steal bases, sacrifice hits, or make pitching changes impacting the game's flow and outcome.
