CleanFuego is an essential training device for any baseball player looking to learn or polish pitches, ​learn to better grip and release, work out subtle changes in real-time, and so much more. Learn the proper feel and release of fastballs, curveballs, change-ups, and sliders. The CleanFuego Set includes one red regulation weight Fuego (5.25oz) and on blue overload Fuego (8oz). CleanFuego Regulation was engineered to replicate the exact dimensions of a regulation baseball (5¼oz) including weight, size and seam orientation. A CleanFuego Overweight (8oz) also replicates the dimensions of a baseball, but is slightly heavier. This helps players work Fuego into their weighted ball training programs. CleanFuego is used by big league baseball players, but can easily be useful to baseball players at any level.
