A support device for ball striking practice is disclosed, which includes a pole to which a ball for striking practice can be tethered. The device is sufficiently stable to withstand the torque and other forces produced in the pole by such striking, but is also completely portable and can be easily transported from place to place and readily set up for use and taken down following such use. The pole of this invention folds easily into a compact package which can be stored, transported in a car or other vehicle, and subsequently can easily be unfolded and rapidly set up and locked into position for use.
