Abstract: A tubular sleeve is made of a tufted fabric having a pile on an interior surface. A pair of spaced-apart tennis balls each has a diameter exceeding a diameter of the tubular sleeve so that the sleeve engages the balls. The balls are manually positioned within the tubular sleeve. Each of the tennis balls has a fuzzy napped exterior surface. A pair of handles are attached at opposing ends of the tubular sleeve. The pile of the sleeve and the napped surface of the tennis balls are of such substance as to naturally engage in holding the tennis balls in selected engagement positions within the tubular sleeve, yet the balls are able to be manually moved to alternate engagement positions within the sleeve, without purposeful disengagement of the balls and the sleeve.
