Abstract: An improved tennis ball carrier adapted to be carried on the person of a player comprises an axial structure divided into two axially aligned compartments and provided with a retaining lip at the mouth of each opposed open end, at least one side opening or means permitting fingers to access the mouth-opposing back side of an enclosed tennis ball and means for maintaining a snug hold on enclosed tennis balls under game playing conditions, but which still permits ready access to the back side of the ball. A belt or other clothing attachment may be provided permitting a player to harness the device to the body. A tennis ball held by the device may be released by applying finger pressure to the back side of the enclosed tennis ball compressing the ball sufficiently while urging it past the lip retaining it in the enclosure.
