Abstract: A device is provided that can be carried by a tennis player, which allows the player to easily store and receive tennis balls. The device includes a substantially rigid tubular member whose inside closely surrounds a standard size tennis ball, and which has a wide slot at one side through which a tennis ball can pass when resiliently deformed. With the tubular member at the player's back at waist level, the player can place a ball anywhere against the slot and press the ball through the slot into the tubular member, or reach through the slot to grasp a ball and pull it out through the slot or through an open end of the tubular member.
