    • Generally L-shaped batter training aid devices may be removeably but fixedly attached to a handle portion of a conventional baseball bat. Preferably, the baseball batter training aid device will include a spacer arm member and a training handle member. The spacer arm member has inner and outer ends and adapted for removable attachment at the inner end thereof to a handle portion of a baseball bat. The training handle member has upper and lower ends and is rigidly connected to the outer end of the spacer arm at substantially a perpendicular junction therebetween so that when the inner end is attached to the handle portion of the baseball bat the training handle member will be laterally spaced from and axially parallel thereto. A knob is preferably fixed to the lower end of the training handle member. The inner end of the spacer member may include a clamp system for clamping the device to the handle portion of the baseball bat.
