    摘要: A system for determining and generating a graphic visualization of a ball flight parameter includes: a ball flight tracking system configured to detect a ball in flight, the ball flight tracking system detecting seam orientation; a processor coupled to the ball flight tracking system and configured to determine a hemisphere plane angle and seam angle of the ball in flight and to determine a coefficient of a seam shifted wake force based on the determined hemisphere plane angle and seam angle, the processor further configured to calculate the seam shifted wake force based on the determined coefficient of the seam shifted wake force for multiple locations on the ball, and generate a visualization of the seam shifted wake force on the multiple locations on the ball; and an output device coupled to the processor to output the visualization of the seam shifted wake force on the ball to enhance pitch analysis and accurate pitch design.

    摘要: A training device includes a device body having a body circumference, a body length and a body diameter. The device body is cylindrical in shape and includes a body side and body first and second ends. The training device includes side strips each having a strip width extending along the body circumference and a strip length extending along the body length, wherein each side strip extends along the body length and are equally space apart along the body circumference, wherein the side strips include two opposing side strips having three ribs extending out of a strip surface to extend across the strip width and to be equally spaced along the strip surface. The training device includes end strips which extend across the body diameter on the body first and second ends to connect opposing side strips and form a cross shaped pattern on the body first and second ends.
