Abstract
A trainer for hitting a baseball comprises a cylindrical pole extending upwardly from a base member placed in front of home plate and toward the half opposite from where the batter using the trainer stands so the upright cylindrical pole is substantially in line with the outside edge of home plate, a lower strike zone indicating shaft extends laterally from the pole at the level of the lower edge of the strike zone upper strike zone indicating shaft extends laterally from the pole at the level of the upper edge of the strike zone, and a ball positioning shaft with a ball tee at one end and a simulated baseball at its opposite end extends laterally from the pole at any selected level between the upper and lower strike zone indicating shafts. The ball positioning shaft is slidably mounted on a rotatable swivel block whereby it can rotate about the pole to position either the ball tee at one end or simulated baseball at the opposite end at any selected position between the inner and outer edges of the strike zone. The outer end of the lower strike zone indicating shaft terminates in line with the inner edge of the strike zone. The outer end of the upper strike zone indicating shaft terminates in line with the longitudinal mid-line of home plate.
