Baseball is the sport that uses a bat and a ball on a diamond-shaped field. The game consists of two teams, each taking turns to bat and field. The objective is for the batting team to score runs by hitting the ball, running around a series of bases, and returning to home plate. Baseball is known for its distinct rules, including three strikes leading to an out and four balls resulting in a walk. The diamond shape of the field aligns with the bases arranged in a square, with the pitcher's mound at the center.
