The sport that uses a bat and ball on a diamond-shaped field is baseball. Baseball is characterized by two teams, typically comprising nine players each, who take turns batting and fielding. The game unfolds on a field with four bases arranged in a diamond shape, with a pitcher's mound at its center. The objective for the batting team is to score runs by hitting the ball and running around the bases, while the fielding team's aim is to get the batters out. Baseball has rich traditions and is especially popular in the United States, Japan, and various countries in the Caribbean and Latin America.
