In baseball, pitchers use the so called changeup pitch to fool the batter. A changeup is intended to look like a fastball, but is slower. The changeup is typically thrown after a fastball, often after consecutive fastballs. Then, seeing the normal fastball arm and body motion of the pitcher, the batter believes the ball is again coming fast and swings accordingly. When the changeup works, the unexpected speed results in the hitter making feeble or no contact with the ball.

As pitching great Warren Spahn said, "Hitting is timing. Pitching is upsetting timing." main
