Definition: The windup is the series of rhythmic movements a pitcher makes before throwing the ball toward the batter. It involves stepping back, lifting a leg, and rotating the body to build up the power and momentum needed for a fast pitch.
Pitchers use the windup when there are no runners on base because it allows them to use their full strength for maximum speed. However, because the windup takes a long time to complete, pitchers usually switch to a quicker motion called the “stretch” when runners are on base to prevent them from stealing. The windup is often a pitcher’s “signature” move, with some being very simple and others being very flashy.
Example: The pitcher went into his full windup and delivered a 95-mph fastball right into the catcher’s glove.
