SPIN VISION BASEBALLS (2X)

Focus on the basics and improve your overall throwing technique with these four-seam balls. The striped ball turns purple when thrown to give instant feedback on revolutions per minute. The ball will only turn purple if you use proper throwing form to promote better arm angles. The color-changing design makes practicing the perfect fastball fun for young athletes, throw after throw. While the white ball features a black spin guide and raised stitching to provide guidance on grip and proper backspin. Consistent practice builds muscle memory to improve overall performance. After practicing with the pitching coach, you will be ready to throw someone out at the plate, throw a double play, or walk onto the mound knowing you will throw a strike. Both balls are the same size and weight as a standard baseball. Perfect for athletes ages 12 and under.
