Release points

with my palmball my release point is much lower than my fastball

bad? how do i fix it? releasinh the ball at fastball release makes the ball go 20 feet high

Need a video, but probably your arm isn’t starting at the same position and is dropping from there. Make sure your hand separation and arm movement to the high cocked position are the same. Many pitchers let things drop on an offspeed pitch. By allowing the arm to start in a lower slot and the dropping it slightly from there through the motion, you tend to ‘sling’ the ball and going high is a result. ALso need to check your lower body mechanics. All the above can cause a shorter stride which can contribute to pitch elevation.
