After 10 years of coaching my son's youth baseball team, I've noticed that when I catch with my son and other young players, the balls they throw often have a sideways or almost horizontal spin. I've also been concerned about the low number of rotations. While factors like small hands relative to the ball size, short fingers, and how they grip the ball likely play a role, more than anything, it seems players lack the awareness to throw a ball with good vertical spin, or even to try to. During form improvement coaching, I tell them not to throw with their hands and to focus on their lower body, but ultimately, the ball is released by the **hands**. It's important to use the fingertips, including the nails, to grip the seams of the ball, rather than the pads of the index and middle fingers. Therefore, this tool might be useful for children in lower elementary grades who bite their nails or have very short nails, to help them understand the importance of their nails. The more vertical the ball's spin and the higher the number of rotations, the more sharpness is added, resulting in a fastball that seems to extend. The ideal pitch is the hopping four-seam fastball, like the fireball fastballs of Kyuji Fujikawa and Atsushi Nakazato of the Chunichi Dragons! When I was little, I used to lie on the floor and throw the ball straight up at the ceiling. Nowadays, children seem to spend more time holding game consoles than balls indoors. The usage is very simple. For a right-handed thrower, hold the handle with your left hand, place your fingertips on the seams of the ball, and just spin it. If you can apply spin properly with your fingertips, even a child can achieve over 5 rotations per second (confirmed with slow-motion video). For detailed instructions, please refer to the enclosed paper at the end of the photos. Let's train the feel of ball release through play. Ideally, we'd like children from kindergarten age, before they join a team, to use this as a toy and spin it around. By playing with this toy and simultaneously practicing throwing the actual ball into the glove's pocket (this is also important, please let them do it), you can further strengthen your release and snap. Additionally, we offer a slight discount on sets that include the yellow tube for inner muscle training and the green tube for form improvement.
