Teaching the Changeup: Arm Speed, Grip, and the Safest Secondary Pitch

Ask experienced pitching coaches what pitch a young thrower should learn after the fastball, and the answer is almost unanimous: the changeup. It is the safest secondary pitch a youth arm can throw, it teaches feel and deception, and it does not carry the elbow-and-shoulder risk that breaking balls do at young ages. This guide explains why the changeup works, how to coach it, and how to use the circle-change arm-speed and feel throwdown drill to build it.

Why the changeup, and why now

The deception in a changeup comes from one thing: it has to look exactly like the fastball coming out of the hand. The hitter starts their swing based on arm speed and release, and a good changeup gives them the same picture — then arrives 6 to 12 mph slower, wrecking their timing. The instant a pitcher slows the arm to take speed off, the picture changes and the hitter adjusts. So the entire skill is learning to throw it hard while a deep grip and a slight inward turn of the hand bleed off the speed.

That is also exactly why it is safe. The arm does the same thing it does on a fastball — there is no violent supination, no snapping the wrist sideways, none of the mechanics that make breaking balls risky for developing arms. MLB and USA Baseball's Pitch Smart guidelines are explicit for the youngest pitchers:

"Avoid throwing pitches other than fastballs and change-ups." — MLB Pitch Smart, Ages 9–12 (source)

The changeup is the one off-speed offering that fits inside that guidance. It lets a young pitcher learn to disrupt timing and change speeds — a real competitive weapon — without touching a curveball or slider before the body is ready.

How the pitch actually works

Two grips cover almost every young pitcher. The three-finger changeup sits deeper in the hand with three fingers across the top; it is forgiving for smaller hands and is the recommended starting point. The circle change forms an "OK" sign with thumb and index finger on the side of the ball, the other three fingers on top — it adds fade and a bigger speed drop but needs a bigger hand to control. Coaches widely advise starting with the three-finger grip and only moving to the circle when the hand can manage it.

The magic move is keeping full arm speed. As Driveline notes, the velocity gap matters but it cannot come at the cost of arm action — pitchers who try to throw far slower than roughly 10–12% off the fastball start visibly decelerating the arm. The cue 'let the grip take the speed, not your arm' captures the whole skill.

"Any slower than this and the arm has to begin slowing down — it's very rare to see pitchers throw a pitch much slower than 10–12% with their normal delivery and full arm speed." — Dan Blewett (source)

A slight inward turn of the palm at release (pronation) helps the ball come out softer and adds late arm-side fade, and finishing the pitch down keeps it out of the hitter's happy zone.

How the drill builds it

The drill is deliberately low-stress feel work. The pitcher alternates short sets of fastballs and changeups and asks a partner to call the pitch by watching only the arm. If the partner can read it, the arm slowed down — instant, honest feedback. Filming from the side makes the comparison concrete: the arm on the fastball and the change should look identical. Full setup, cues, and the on-knee-to-mound progression are on the drill page. Coaches recommend throwing 10–15 changeups at the end of catch play so the feel compounds over weeks.

Mistakes to watch for

The number-one error is the most natural one: slowing the arm to take speed off. It feels like control; it is actually tipping the pitch. Watch also for the change floating up — a high changeup is the easiest pitch in the world to hit, so cue 'finish it down.' Watch for pitchers gripping the ball on the fingertips like a fastball instead of seating it deep in the hand, which leaves the speed gap too small. And do not let a young pitcher force a circle change before the hand can wrap the ball; the three-finger grip will teach the same feel without the fight.

Age-appropriateness

This is a green-light pitch for youth. Coaches commonly introduce a changeup around ages 8–9 depending on hand size, and Pitch Smart endorses it as one of only two pitch types for the 9–12 group. Breaking balls are a different conversation entirely — Pitch Smart advises that players "begin using breaking pitches after developing consistent fastball and changeup" command, and only once a pitcher is older and closer to physical maturity (source). In other words, the changeup is not a stepping stone you rush past — it is the foundation, and many pro pitchers will tell you their changeup is their best pitch.

Takeaway

If you coach one secondary pitch to a young arm, make it the changeup, and make the whole lesson about arm speed. Keep the reps light, frequent, and competitive — let a partner try to read the arm — and the deception takes care of itself. It is safe, it is effective, and it teaches the feel every other pitch will eventually borrow from.
