Devices, methods, and systems for slowing the descent of an object in flight such as a baseball using a parachute are presented. A parachute assembly includes a canopy attached to a plurality of suspension lines converging downwardly to a corresponding number of attachment points on the surface of a ball. The attachment points are substantially equidistantly spaced apart along a line of substantially equal latitude. In one embodiment, each attachment point defines an opening to an interior channel extending to a central chamber. Each suspension line is inserted into an interior channel, through the central chamber, and out of the ball through a common shaft, where the lines are fastened together in a bundle and then withdrawn until the bundle lies in the central chamber, retaining the lines inside the ball. |
