The sport played with a bat and a ball in a diamond-shaped field is baseball. In baseball, two teams compete to score runs, with the game structured around batting, fielding, and pitching. The diamond-shaped field consists of four bases arranged in a square. The objective is for the batting team to hit the ball and manage to run around the bases to score runs, while the fielding team aims to prevent runs and get batters out. Baseball has a rich history, particularly in the United States, and is often referred to as America's pastime.
