a base having a forward end and a rearward end;

a transverse support cross-member extending across said base;

an axle arm mount extending from said base, a sleeve disposed on said axle arm mount;

a throwing arm lever disposed along one side of said axle arm mount;

a throwing arm disposed on a second side of said axle arm mount;

a bearing assembly disposed in said sleeve, an axle extending through said sleeve and supported by said bearing assembly, said axle operably connected to said throwing arm lever and said throwing arm; and,

said one side being toward one end of said axle and said second side being toward a second end of said axle, so that said throwing arm and said throwing arm lever are offset;

a spring extending from said throwing arm lever to a movable leg, wherein the moveable leg, the spring and the throwing arm lever are all located on one side of the base.

2. The throwing apparatus of claim 1 , said moveable leg being pivotally connected to said base.

3. The throwing apparatus of claim 1 , wherein one end of said spring is adjustable relative to said moveable leg.

4. The throwing apparatus of claim 1 , said base comprising a foot at one end of said base.

5. The throwing apparatus of claim 1 , further comprising a mounting block operably connected to said throwing arm.

6. The throwing apparatus of claim 5 , said mounting block operably connected to said axle.

7. The throwing apparatus of claim 1 , said throwing arm having a first surface and a second surface angled relative to the first surface.

8. The throwing apparatus of claim 7 , said throwing arm having a plurality of adjustment apertures.

9. The throwing apparatus of claim 1 , further comprising a release arm having a handle.

10. The throwing apparatus of claim 9 , said release arm having a release finger with control guides.

11. The throwing apparatus of claim 10 , further comprising an angled surface disposed between said control guides.

12. The throwing apparatus of claim 1 , said leg comprising a foot pedal at an end thereof.

a transverse cross-member at one of said forward end or said rearward end extending across said base;

an axle arm mount extending above said base;

a throwing arm lever disposed along one side of said axle arm mount;

a throwing arm disposed on a second side of said axle arm mount;

a sleeve disposed on said axle arm mount and oriented horizontally, a bearing assembly disposed in said sleeve, an axle extending through said sleeve and supported within said sleeve by the bearing assembly, said axle operably connected to said throwing arm lever and said throwing arm wherein said throwing arm lever and said throwing arm are disposed near opposed ends of said axle;

a spring extending from said throwing arm lever to a movable leg, said moveable leg pivotally connected to said base, said spring, said throwing arm lever, and said moveable leg disposed on one side of said base; and,

a release which retains or releases said throwing arm from a cocked position to throw a ball.

14. A throwing apparatus, comprising:

a base having a forward end and a rearward end;

a cross-member at one of said forward end or said rearward end extending across said base;

a sleeve elevated from said base and positioned on an axle arm mount extending above said base, said sleeve oriented horizontally;

an axle extending through said sleeve and supported by a bearing assembly within said sleeve, said axle operably connected to a throwing arm lever near one end of said axle and a throwing arm near a second end of said axle, spaced from said throwing arm lever;

a spring extending from said throwing arm lever to a movable leg, said moveable leg pivotally connected to said base to energize said spring;

said spring, said moveable leg and said throwing arm lever all located on one side of said base;

a release which retains or releases said throwing arm from a cocked position to throw a ball.
