Abstract: The present invention is a method and apparatus for use with a ball throwing machine (e.g., baseball/softball pitching machines, tennis ball serving machines and the like) that may be employed for practice at hitting and/or catching balls thrown. In many conventional systems, such machines have a fixed position and are unable to vary the direction (horizontal) or angle (vertical) at which a ball is thrown. The present invention provides a simple, cost-effective device by which conventional machines may be adapted to provide randomly variable movement of the machine so as to enable a ball to move about a target location in order to simulate a competitive environment.
