发明名称 Stripe Marked Baseball and Softball
摘要 Softballs and baseballs are provided as training devices to train an athlete to throw a ball with control of rotation. The training device consists of a spherical object covered by two smooth coverings stitched together and an ink or dye stripe or marking of any color around the circumference of the sphere. The training device is manufactured with a stripe which is between 0.75 inches in width and 2.00 inches in width. The stripe on the training device runs perpendicular or oblique to the stitching. When thrown, the stripe allows the athlete to visually identify the rotation which he or she has caused. Once acquired, the ability to control the rotation of a ball minimizes the ability or opportunity for an opponent batter to make efficient and efficacious contact with the ball.
