Baseball is a bat-and-ball sport played between two teams, each consisting of nine players. The game takes place on a diamond-shaped field with four bases: first base, second base, third base, and home plate. The objective is to score runs by hitting a pitched ball and running around the bases. The game is divided into nine innings, with each team taking turns to bat and field. A team scores a run when a player successfully reaches home plate after touching all four bases. Key elements of the game include the pitcher, batter, and umpire, who enforce the rules.
