There are four bases on a baseball field. They are located at the corners of a diamond-shaped infield and are numbered in a clockwise direction starting with first base, which is located in the lower left-hand corner of the infield as viewed from home plate.
The bases are typically made of white rubber and are 15 inches (38 cm) square, with the corners pointing outward. Each base is spaced 90 feet (27.4 meters) apart from the adjacent bases, with home plate located at the center of the diamond.
The bases play a critical role in the game of baseball, serving as the destination for runners who are trying to score runs. Runners must touch each base in order, starting with first base, in order to score a run. If a runner fails to touch a base or touches them out of order, they can be called out by the umpire.
Overall, the bases are an essential part of the game of baseball, and their placement and dimensions are carefully regulated to ensure fair play and consistency across different fields and levels of play.
