In a previous post I described what I cal the Law of Opposites, which essentially states that to make a ball move in one direction you must first go in the opposite direction.

There is a corollary to this law however. It applies to the changeup. This law says that to make a ball go slow, you must go fast. Not for one of those weak slow your arm down types of changes, but for a true change where you disguise the pitch speed.

Even those who are throwing a true change sometimes will let up off the pitch, especially at the end. That is the wrong approach to take. What it will do is actually make the change faster than it should be. Instead, you should focus on bringing the arm around as fast at you can. Going fast will take you past the normal point of release for a fastball, helping you release the ball at a weaker point. Throwing the ball from a weak release point, of course, will make it go slower.

It is counter-intuitive, but it works. Keep the arm speed up throughout and you’ll have greater success with the change.
