Abstract Ball practice support structure providing high strength, durability, and adjustable features while being collapsible for shipment and storage. This support structure is adaptable to either overhead, sidewall, or combination of overhead and sidewall mounting. Telescopic support arms permit adjustment of the position of a tethered ball in relation to overhead or sidewall.
