Abstract: A device for practicing an address stance and ball-hitting motion in sports such as baseball, softball and tennis. A hitter stands on a step plate (30) and a swivel plate (31) mounted on a flat base (12). The plates have adjustable separation, with the step plate fixable in a plurality of locations relative to the swivel plate. The plates align the hitter's feet using toe stops (36). The step plate (30) has a foot guard (34) that forces the hitter to step toward the pitch. The swivel plate (31) rotates about a vertical axis, and has foot-retaining straps (38, 39) that allow the heel to lift. The hitter learns to step toward the ball and swivel the back foot while swinging, turning the body, and shifting weight toward the ball. The foot plates (30, 31) are reversible on the base (12) for right or left-handed use.

Abstract: A device for practicing an address stance and ball-hitting motion in a sport such as softball. A batter stands on a step plate (30) and a swivel plate (31) mounted on a flat base (12). The plates have adjustable separation, and align the user's feet using toe stops (36). The step plate (30) has foot guards (34) that force the user to step towards the pitch. The swivel plate (31) rotates about a vertical axis, and has foot-retaining straps (38, 39) that allow the heel to lift. Swivel stops (18, 20) limit the rotation range between address alignment and a safe maximum swivel. The user learns to step toward the pitch and swivel the back foot while swinging the bat, turning the body, and shifting weight toward the pitch. The foot plates (30, 31) are reversible on the base (12) for right or left-handed use.
