Abstract: A knob sleeve for a ball bat extending along a longitudinal axis and having a tubular handle portion and a knob attached to the handle portion. The knob sleeve includes a tubular body having a distal end and a proximal end. The body defines a central bore for receiving the handle portion. The body includes at least first and second regions positioned adjacent the distal and proximal ends of the body, respectively. The first and second regions have first and second maximum outside diameters, respectively. The second maximum outside diameter is greater than the first maximum outside diameter. Each of the first and second regions has a height measured with respect to the longitudinal axis of at least 0.4 inch.
