Batting cages are enclosed or partially enclosed pieces of sporting equipment that act as a "catcher," in effect, for batters practicing hitting baseballs or softballs. Batting cages help to keep balls in a contained space so that the batter can continue hitting without having to continually retrieve them. Different types of batting cages can be located outdoors or in a gym or activity center.

Batting cages are both in professional, school-sponsored, and recreational baseball and softball. They can be used to help improve a batter's speed or to improve his or her accuracy in hitting a ball. A batter's agility and stance, as well as his overall performance, can be enhanced by using a batting cage. While aiding a batter in improving his or her skill, batting cages also keep the ball in an enclosed area to prevent the injury of bystanders and onlookers.

Batting cages consist of a configuration of netting over a frame. They can differ in material, size, and cost, as well as structure and workmanship. Whether batting cages are used indoors or outdoors can be a deciding factor in what the best choice of material should be. Cages that are used outside will need to be tougher than those used indoors.

The netting in batting cages can be constructed of various materials and degrees of sturdiness. Framing in a batting cage should be constructed with a pipe that will withstand temperatures and weather in the area in which it is used. For that reason, a batting cage used by the Boston Red Sox will probably be made differently than one used by the Los Angeles Angels.

With less time spent retrieving baseballs, batters can spend more time advancing their technique. For decades, batting cages have played a central role in improving the swings of professional and amateur batters.
