How To Grip And Throw A Circle Changeup ( Part 5)

Circle changeup

The circle changeup and the four-seam fastball are what got me to professional baseball. They're both great pitches.
To throw a circle changeup make - quite literally - a circle or an "OK" gesture with your throwing hand (using your thumb and index fingers). You then center the baseball between your three other fingers (as shown in the middle picture above right). The baseball should be tucked comfortably against the circle.
Throw this pitch with the same arm speed and body mechanics as a fastball, only slightly turn the ball over by throwing the circle to the target. This is called pronating your hand. (Think about this as giving someone standing directly in front of you a "thumbs down" sign with your throwing hand.) This reduces speed and gives you that nice, fading movement to your throwing-arm side of the plate.
A great way to develop the "fastball mechanics" but changeup speed is to practice throwing your changeup as you long toss (throwing beyond 90 feet). Alternate fastballs and changeups at 90-or-more feet for about 20 throws a couple of times a week.
