A tubular aluminum bat frame is provided with a large-diameter impact portion, an intermediate tapering portion, and a small-diameter handle portion. A tubular insert is suspended within the impact portion by interference fits at each insert end. A first interference tit is achieved by forcing the first end of the insert into the tapering portion of the bat frame. The second interference-fit is then formed by curling the end of the impact portion over upon the second end of the insert. A gap exists along the length of the suspended insert separating the insert from the interior of the impact portion. The gap is filled with grease to facilitate relative movement between the insert and the tubular frame when a ball is batted.
