Why Do Some Pitchers Throw More Changeups When Ahead in the Count?
The best time to surprise a hitter is when the hitter expects something else.
Count leverage changes hitter behavior. When a pitcher reaches a favorable count such as 0-2 or 1-2, the hitter knows a strikeout is possible and often prepares to react quickly.
That urgency creates an opportunity for off-speed pitches. A well-located changeup resembles a fastball initially but arrives noticeably slower, disrupting timing.
The effectiveness of the pitch depends on its relationship to the fastball. The greater the deception, the more difficult it becomes for hitters to adjust.
Pitchers who command both pitches effectively can force hitters into impossible choices. Sitting on the fastball leaves them vulnerable to the changeup, while anticipating the changeup may make them late on the fastball.
