3. The batting aid of claim 1, further comprising at least one U-bolt for anchoring said cable to said inner tube.
4. The batting aid of claim 1, further comprising means defining holes through said ball, through which said cable passes to firmly anchor said ball to said cable.
5. A batting aid for instruction of batters or warm-up of competitors comprising:
a main frame comprising a horizontal arm, and having a mounting end and a ball holding end;
a mounting assembly for securing said main frame to a supporting structure
an adjustable slide tube assembly mounted on said main frame ball holding end, and having a lower end, said adjustable slide tube assembly comprising an outer tube pocket affixed to said main frame ball holding end, and an inner slide tube, there further being a plurality of matching pairs of apertures thorough said tube pocket and said inner tube, and a pin for insertion through selected apertures to vertically adjustably position said inner tube within said outer tube pocket;
a cable attached to said tube assembly lower end; and
a ball anchored to said cable; whereby
said main frame provides a stand-off distance from said ball to said mounting assembly, and said ball is adjusted in height from the ground by said adjustable slide tube assembly.
6. The batting aid of claim 5, further comprising at least one U-bolt for anchoring said cable to said inner tube.
7. The batting aid of claim 5, further comprising means defining holes through said ball, through which said cable passes to firmly anchor said ball to said cable.
