Abstract: A baseball practice mechanism defined by a tripod mounted framework supporting a baseball propelling arrangement and including a pivotal structure controlling a desired training need, as, for example, flyballs, batting practice, grounders, or the like. The tire speed is accomplish by use of an adjustment thread cooperatively engaging a pivotal plate which bears against the housing of a power source, serving, in end purposes, as a variable speed control for the rotation of the baseball propelling tire. Baseball feeding is accomplished through an entry opening into a V-shaped cup, providing safety to the user and, at the same time, the positive and repetitious squeezing, and propelling, of the baseball in a controlled direction through simple pivotal action. The mechanism is mobile through pulling movement of one or more of the tripod base legs combined with the rotating action afforded by the tire.
