## Description

Leather Baseball Spinners

## Features

- BASEBALL TRAINING BALLS: The Play9 Throwing Baseball Spinner with 2 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 SPINNER BALLS: With our 4-seam, 2-seam, regular, and curveball baseball spin trainers, 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 TRAINER 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 SPIN BALL: Play9 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.
