There are plenty of different Change Up grips to try/use.
• Comfort.
• Maintain normal tempo of delivery.
• You MUST have the same arm speed with it as you do with your fastball.
• Throw it enough times in catch and in games to where you have just as much confidence in it as you do your fastball.
The grip in the pic is the grip I have found that feels the most comfortable to many and has proven to be the easiest to command. Think fastball with your middle and ring fingers. With that, it doesn’t work for everyone. Find a grip that works. Stick with it even if you have an off day with it.
Force reps in game situations with it. The only way to build confidence with it is to throw it to live batters.
The biggest issue I see is young pitchers chocking their CH grip too deep in their palm. This makes it tough for most to command. It should rest at the base of your fingers. Think about where your hand would callus up with a lot of hitting. Notice this in the pics.
Myth…The thumb does not need to be on the side of the baseball like many believe. While this may take some additional speed off, it can make it very tough to command. It’s OK to have your thumb directly underneath, as you see where my thumb is in the pics.
If the grip isn’t taking enough speed off, there are things you can do with your lower body to help take speed off.
• Less back leg drive.
• Drag longer.
• Think to leave your foot on the rubber as long as possible.
• Fall instead of drive with the lower half.
Though more advanced, I have seen all of these help different pitchers. Find which one works best for you, or your pitcher(s).
Hope this helps some of you. Throw that Change Up!!
