A baseball is a very detailed ball that is made precisely with care. A baseball has exactly 108 stitches on it shaped in a specific pattern to help the ball fly. Although, it can make it fly in very different directions depending on how you use them. All the pitches and more that were listed all depend on the stitching of the ball to direct it in the way it should go. As air travels on and around the stitches it pushes the ball in the direction that the air has strong push on. This is how a curveball is thrown because when the ball is released in such a manner that the stitches cause a change in airflow in the middle of flight making the ball curve like it is supposed to do. They can have such an effect that a pitcher can pitch a 85 mph fastball
