About this item

• BASEBALL TRAINING BALLS: The Play 9 Throwing Baseball Spinner 4 seams is a training ball for baseball players that provides instantaneous feedback on every throw. It is engineered for youth & professional players to help them develop proper throwing mechanics for all types of pitches.
• PLAY 9 SPINNERS: With our 4-seam, 2-seam, regular, change up and curveball baseball spinners, you can improve pitch efficiency, accuracy, and spin rate. The goal is to get behind the baseball and release it flawlessly. When done correctly, the ball will have a little wobble and rotate smoothly.
• PITCHING TRAINING BALL: This baseball training aid is designed to teach the pitching spins and rotation directions in fastpitch baseball. Be it the basics of releasing the baseball or the advanced spins of the rise, curve, or drop, the Play9 Baseball Spinner is an essential tool to develop pitches like a fastball, split-finger fastball, curve, change, slider, sinker, and screwball.
• LEATHER SPINNIER BASEBALL: Play 9 Baseball Spinner is made of premium cow leather, the same material as a real ball. Unlike other spinner training balls made of plastic, which becomes slick when your hand sweats in cold, wet, or hot temperatures.
• FOR ATHLETES & COACHES: By using the device's visual feedback, athletes can experiment individually and improve through discovery learning. After achieving the goal of throwing the device efficiently (alternating throwing the Spinner and baseball), throws of the Spin Ball should be blended with throws of a regular baseball, transferring newly acquired skills.
