A paddle bat is a great way to make sure that you are getting palm-up, palm-down during your swing. Crafted with a normal knob and a full size barrel that is cut in thirds, these are the only flat training bats on the market that have a game bat feel to them. Make sure that you are driving the ball instead of rolling over or cutting underneath it. Warranty is void if used with normal baseballs. Please use softies, or tennis balls.
