1. A ball having an ovaloid shape with back and front tips, a longitudinal axis, an elliptical longitudinal cross section and generally circular transverse cross section and having at its back tip a tail appendage consisting of an elongated, flexible sheet strip having a length from 4 to 72 inches and a width from about 0.5 to 4 inches which is fixedly attached at one end only to said ball, substantially in alignment with said longitudinal axis and which has an unattached opposite end so that said appendage provides sufficient drag when said ball is thrown to cause the back tip of the ball to align itself with the front tip thereof, thereby resulting in a straight and accurate flight of the ball.
