ABSTRACT:
An apparatus for practicing tennis strokes, especially ground strokes, provides a support for holding a tennis ball at an initial predetermined position while allowing for a rotation of this ball about a horizontal axis of the support, this horizontal axis support being allowed to move along a predetermined ideal longitudinal axis and being biased to return to its initial position, whereby an irregular stroking of the tennis ball results in a less than ideal operation of the apparatus which is readily detected.
