New and effective, the AST (patented) is unlike any other swing trainer available. Designed to help experienced players perfect their bat skills, a forward arm and outside swing barrier simultaneously eliminates both "dipping" and "casting". And, the height adjustable, moveable arm positions the ball anywhere across the strike zone to realistically represent inside and outside pitch locations. Use the AST to build a compact swing, keep the "hands inside the ball" and develop a "quick" bat. Use it to increase bat speed and learn to "hit the ball where it's pitched".

Includes a two year manufacturer's warranty.
