Abstract
A baseball bat which can minimize the slippage between the bat hitting surface and the ball at the instant of impact with the ball. Increased adherence between the ball and the bat hitting surface allows a spin to be easily imparted to the ball, so that the flying distance of the ball can be increased. The metallic baseball bat includes numerous longitudinal polishing streaks extending along the longitudinal axis of the metallic bat.
