How to Throw a Changeup with Pitch Design

how to throw a changeup

When you log over 5,000 pitches through the Rapsodo camera and spend countless hours crunching data you begin to have a pretty good understanding of ball movement and behavior on a pitch-by-pitch basis.  Today we’re going to review how to throw a changeup with pitch design, in great detail. 

How to throw a changeup?

First, let’s get this straight.  There seems to be no shortage of how pitchers grip their changeups.  Consequently, you see a great deal of variation in change-up pitch movement from pitcher to pitcher.  But a decent changeup generally features the following:

    1. First and above all else, creates an illusion with an identical fastball arm speed
    2. Velo reduction of 8-12 mph
    3. A combination of arm-side and sinking movement
    4. Lower spin rate than fastballs
    5. Movement differentiation from the fastball

The end goal of the change-up pitch is to disrupt the hitter’s timing and create a swing and miss pitch, and a good one will maintain fastball arm speed but arrive at the plate with lower velocity. We can generally do this by placing the ball deeper into our hands (think palm ball) and minimizing our leg drive a little bit by dragging the back foot slightly to reduce forward momentum and velocity.  To put the changeup in some context, here is a summary of 2017 MLB data.  Total Spin and Velo is lower by approximately 21% and 8 mph, respectively.


The direction of movement of any pitch is directly related to its spin axis and the change-up pitch is no different.  A pitcher’s changeup movement / break can be extremely individualized and much of this is undoubtedly in the grip and final release.  How to throw a changeup well is both a function of the grip and how the ball is released at the last micro second.

With its many potential grips, the change-up pitch may behave differently from pitcher to pitcher and generate movement along a larger area on the movement chart, with tilt axes ranging from that near a 4-seam all the way past a 2-seam.  The following 2 diagrams chart 5 pitchers and their changeups with velo drops ranging from 8-12 mph vs. their 4-seam:

As the spin axis (listed next to each pitcher in the diagram above) tilts farther and farther from near 00:00 towards 03:00, the vertical drop is replaced by horizontal drop. There is no wrong or right here with a change-up pitch, just three basic requirements on how to throw a changeup:

    • Slower by at 8-12 mph vs. the fastball
    • Create enough deception with fastball arm speed
    • Create sufficient movement differentiation vs. the pitcher’s fastball

Here is a good comparison between Pitcher E’s 4-seam and changeup from the images above:


Below is the high-speed video of the same changeup.

There are three takeaways from this video:

    • Without the horizontal left to right movement this ball would have missed the strike zone by approximately 1½ ft on the left side
    • Spin-axis is directly correlated with direction of movement
    • Spin-axis is being highly influenced by the final point of contact with the ball, in this case the ring finger. If you didn’t notice it in the video, take a closer look at the video below.  The ring finger at the final moment shapes this change-up pitch and its significant horizontal movement

Here is high-speed footage on the changeup from the front.  Do you want to see how to throw a changeup pitch?  Observe the ring finger at the final point of release.

Knowing what makes a good changeup is one thing, but actually delivering on it is a whole other thing. As mentioned earlier, the primary objective is to create an illusion with an identical fastball arm speed. But if you understand what creates the degree and amount of movement, then it can be further developed in many ways including grip, finger pressure, arm slot and small movements at the final point of release.  And finally, knowing how different pitchers react to different cues through trial and error is where the art comes in.
