A ball holder includes a first and second hollow hemispherical shell, each having a plurality of apertures therein. Each hemispherical shell includes a respective hinge part, and, diametrically opposed therefrom, a respective closure element. The first and second hinge parts are connected with each other, enabling turning the first or the second hemispherical shell relative to each other to open or close the ball holder. The first and second closure elements are aligned when the ball holder is closed permitting engagement with a releasable lock therethrough. The ball holder includes a plurality of protuberances spaced apart along internal surfaces of the hemispherical shells. The protuberances separate a ball held within the ball holder from the internal surfaces of the shells, and form discrete contact points to reduce surface contact areas of the ball with the internal surface for effectively drying the ball carried by the ball holder.
