A baseball field, also known as a diamond, is a large outdoor area designed for the game of baseball. It features a grass infield and a dirt pitcher's mound at the center. The field is shaped like a diamond, with four bases: home plate, first base, second base, and third base. The outfield extends beyond the infield and is typically covered in grass. Foul lines run from home plate to the outfield, marking the boundaries of fair and foul territory. The field is surrounded by a fence or wall, which can vary in height and distance from home plate, depending on the specific stadium.
