The Circle Change Up Pitch is one of the deadliest pitches in baseball. A change up does what it says. It changes the pace of a pitchers normal speed, it is intended to fool a batter's eye. A change up pitch looks like a fastball but it is not. A circle change up pitch is slower than a fastball, this pitch is 7 to 15 mph slower. The ball looks like a fast ball to the batter's eyes but it is rotating slower. The pitch is 10% slower then the fastball. It takes a roughly 0.45 mph for the hitter to hit this type of pitch. The angle of the forearm and wrist is also a key element in throwing a circle change up as it depends on the angle in which it is thrown to make the ball spin and rotate from bottom to top. In order to understand a change-up pitch one must understand the speed it has when it is thrown to the batter.

Friction is very crucial to throwing an effective Change up because maximizing the friction of the ball will determine the effectiveness of the circle change up in the game. The pressure from the fingers and the hand make the ball move side to side. It's important for the hand to touch the ball in as many points possible. Once the ball leaves the hand it loses its potential energy meaning that because it's low its speed is much slower than most other pitches.
