Baseball and softball are bat-and-ball sports played between two teams. In baseball, the game is played on a diamond-shaped field with four bases, while softball is typically played on a smaller field. Both sports involve hitting a ball with a bat and running around bases to score runs. The main differences between the two include the size of the ball, the pitching style, and the field dimensions. Baseball uses a hard ball and features overhand pitching, while softball uses a larger, softer ball and employs underhand pitching. Both sports are popular in many countries and have professional leagues.
