Training baseball bat

A training baseball bat, comprising:

• (a) a wooden baseball bat comprising a head portion and a handle portion, wherein a cylindrical axial cavity extends from an end of the head portion which is distal to the handle portion towards the handle portion along a length of the head portion;
• (b) a sealing cap arranged in and sealing the cavity at the end of the head portion which is distal to the handle portion;
• (c) a training apparatus positioned in the cavity, the training apparatus comprising:
• a magnet fixed at an end of the cavity opposite the sealing cap;
• a metal stopper fixed within the cavity adjacent to and spaced from the sealing cap;
• and
• a ferromagnetic cylinder positioned in the cavity between the stopper and the rod and slideable therebetween, wherein the magnet is of a strength to magnetically hold the cylinder thereto until the bat is swung at a sufficient speed and proper arc to release the cylinder from the magnet, and wherein, when released from the magnet, the cylinder is sufficiently slideable in the cavity to travel the length of the cavity and contact the stopper to exert an auditory signal;
• and
• (d) at least two metal reinforcing pins arranged perpendicular to the cavity and perpendicular to and spaced from one another along the length of the cavity between the sealing cap and the stopper, each pin extending through the cavity and across a substantial portion of the diameter of the head portion.
