Diamond Bases are the four corners of a baseball diamond. They are the places where the players stand when the game begins and where they must run to score a point. The bases are located in the shape of a square, with the first base at the bottom left corner, second base at the top right corner, third base at the bottom right corner, and home plate at the top left corner. The term BAGS is an acronym for the four bases, with each letter representing one of the bases: B for first base, A for second base, G for third base, and S for home plate.
