A pump stabilizer stabilizes the position of the needle of a cylinder-type hand-held sport ball pump relative to the sport ball assuring that the needle is not bent or broken-off during the inflation pumping action, while permitting the pump cylinder to be held in one hand and the pump piston handle to be held in the other in typical fashion. The outer cylinder of the pump is fitted with a sliding peripheral ring. The needle end of the pump includes a mounting ring having three mounting tabs or brackets equilaterally spaced about the ring. Three legs are pivotably mounted on the sliding ring and secured to the mounting ring by hinged extensions, permitting the sliding ring to move along the axis of the cylinder and the legs to telescope in and out relative to the cylinder. When the needle is inserted in the orifice of the ball, the legs are telescoped down along the cylinder until they are in firm engagement with the ball. A locking device secures the assembly in place during the pumping action.
