A baseball base is a flat, square object used in the game of baseball. There are four bases on a baseball field: first base, second base, third base, and home plate. Players run to these bases to score runs, and they must touch each base in order while running around the diamond-shaped field. Bases are typically made of rubber or a similar material and are designed to be durable and safe for players. Each base is positioned at specific distances from one another, with home plate being the starting point for batters. The bases are essential for gameplay, as they define the areas where players must run and fielders must make plays.
