A device for training and conditioning players in the hitting of a baseball. A conventional baseball is fixedly attached to the end of an elongated member which is slideably received in a hollow tube. The tube is supported in a substantially horizontal position on the end of a support rod which is vertically adjustable to place the baseball at a desired height, and rotationally adjustable to place the axis of the slide member at a desired angle with respect to the hitter. A coil spring within the closed end of the horizontal tube returns the slide member to its original position after being struck, and thus caused to move forcefully into the tube. The support rod, preferably two telescoping rods, is fixedly attached at its lower end to a flat support plate which rests on a horizontal surface during use of the device.
