text: The changeup, which has variants such as the circle changeup, the vulcan changeup or the palmball, is a slow pitch that is thrown with the same arm motion and arm velocity of a fastball, but with a much different grip that keeps the ball from achieving the same speed; usually the changeup is 10-20 mph slower than the pitcher's fastballs.
