Older players can use the CF brand. - Best for youth 9-15U: The ball weighs right in a 5.19oz and has more "ball" to grip which is helpful for younger players as thew hone their finger snap when releasing the ball.... and because of the lower price point, it doesn't matter as much if the ball gets scratched up from pavement play. The more expensive Clean Fuego brand is ideal for young adult/adult players as those have less "ball" and more flat side to the design: That makes it harder to get a clean spin on the trainer and really dials in a consistent finger snap. I know that Play 9 has different balls available to learn different pitches but this same trainer can be used to throw different pitches just as easily since the release motion should be the same and provide a clean spin. I see some complaints about the center line stripe... While not perfect, it is really only helpful for early early stages of training as the player shouldn't focus so much on the line as they are more focuing on the complete ball having a clean look as it spins to the other player's mitt or glove. Play 9 should add an overload option or two of the 4-seam design. Like a 6oz, 7oz & 8oz to help warm up pitchers and also ensure clean wrist and finger mechanics. Review: 5 stars - Wonderful ## Features - TRACK EVERY PITCH: The Play 9 Spinner (4 Seam) is a pitching trainer featuring a built-in stripe to track spin and provide instant feedback, enabling players to diagnose errors on the fly.

A must-have among baseball training balls, it stands out as one of the most effective training baseballs for pitchers aiming to sharpen their 4 seam fastball. - PLAY 9 SPINNER: Our 4-seam spin trainer helps refine pitching baseball skills by enhancing efficiency, accuracy, and spin rate. The goal is to get behind the training baseball and release it flawlessly. When executed correctly, the ball rotates smoothly with minimal wobble. As one of the best baseball training aids, it’s essential for pitchers looking to perfect their mechanics and improve overall performance. - MASTER YOUR SPIN: This pitching training baseball is designed to improve spin rate, accuracy, and mechanics.
