Changeup

The changeup is thrown with the same arm action as a fastball, but at a lower velocity due to the pitcher holding the ball in a special grip. Leo Mazzone states: "When a pitcher throws his best fastball, he puts more in it; the changeup is such that one throws something other than his best fastball. By having this mindset, the pitch will have less velocity on it in addition to the change in grips. This difference from what is expected by the arm action and the velocity can confuse the batter into swinging the bat far too early and thus receiving a strike, or not swinging at all. Should a batter be fooled on the timing of the pitch and still make contact, it will cause a foul ball or the ball being put into play weakly, usually resulting in an out. In addition to the unexpectedly slow velocity, the changeup can also possess a significant amount of movement, which can bewilder the batter even further. The very best changeups utilize both deception and movement."

Since the rise of Pedro Martínez, a Dominican pitcher whose changeup was one of the tools that led to his three Cy Young awards, the changeup has become increasingly popular in the Dominican Republic. Dominican pitchers including Edinson Volquez, Michael Ynoa, and Ervin Santana are all known to have developed effective changeups in the Dominican Republic after Martinez’s success with the pitch. Volquez threw changeups 31.9% of the time in 2008, more than any other starter, and James Shields threw it 26.3% of the time, tops in the AL.

The changeup is analogous to the slower ball in cricket.
