Basic Pitch Grips
How to hold a four-seam and two-seam fastball and a changeup, plus what the recognised authorities actually say about breaking balls and young pitchers.
A pitcher needs fewer pitches than most people assume. A fastball you can command and a changeup you trust will get almost anyone through a rec-league or youth-league season, and the published development guidance agrees: those two come first, and everything else waits.
This guide covers the grips for those pitches and then, rather than offering our own opinion on breaking balls, sets out what the recognised authorities actually say — including where they disagree with each other, which they do.
General information, not medical or coaching-certification advice. Anything touching a young pitcher's workload should be read alongside our guide to pitch counts and arm care, and arm pain means stop and see a qualified medical professional.
Four-seam fastball
The straightest, most accurate pitch, and the one every young pitcher should master first. It is the pitch to throw when you need a strike.
Find the part of the ball where the seams sit closest together in a horseshoe shape. Lay your index and middle fingers across the seams, roughly an inch apart, so that all four seams rotate through the air on each revolution. That backspin is what keeps the ball on a flat, true plane.
Rest the thumb underneath, roughly centred between the two fingers. Hold it out in the fingers rather than buried in the palm — you want space between the ball and the base of your hand — and keep the grip firm rather than tight. A strangled ball loses velocity and accuracy at once.
Throw it straight through the target with full arm speed.
Two-seam fastball
Slightly slower than a four-seam, with a little arm-side run. Useful for getting ground balls and for moving the ball off the barrel.
Place your index and middle fingers along the seams where they run closest together, rather than across them, so the fingers sit on top of the two narrow seams. Thumb underneath as before.
Some pitchers hold it marginally tighter or shift slightly off centre to encourage movement. The trade is predictable: more run, slightly less command. For most young pitchers, the four-seam remains the pitch to throw when a strike is essential.
The changeup
The changeup is the pitch the development guidance actually asks young pitchers to learn second, and it works on deception rather than force. The whole point is to throw it with fastball arm speed and fastball body mechanics while the ball leaves the hand slower. If the arm slows down, the hitter sees it coming and the pitch is worthless.
USA Baseball publishes grip instruction for three versions in its drills library.
Three-finger changeup. Centre the ring, middle and index fingers on top of the ball. Place the thumb and pinky on the smooth underside — USA Baseball notes that touching those two fingers together helps develop a feel for the pitch. Hold the ball deep in the palm to maximise friction and reduce speed at release. This is usually the easiest for smaller hands.
Two-seam changeup. Place the middle and ring fingers inside the two seams. Throw with the same arm speed as a fastball but with a looser grip and the ball set slightly deeper in the hand.
Circle change. Use the thumb and index finger to make an "OK" sign against the ball, centring it between the other three fingers and tucked comfortably against the circle. Throw with fastball arm speed and mechanics, turning the ball slightly over — USA Baseball describes it as throwing the circle toward the target, mimicking a thumbs-down.
USA Baseball's own drill for this is simply to practise several grips at about 40 feet, switching every ten throws, to find which one feels most natural. That is the right approach: changeup grips are individual, and hand size decides more than theory does.
Breaking balls, according to the people who study it
This is where we hand over to the authorities, because it is a genuine injury question and the published positions are not identical.
Pitch Smart, the joint MLB and USA Baseball programme, is the most directive. For ages twelve and under, its published guidance is to "avoid throwing pitches other than fastballs and changeups." From age thirteen the wording changes to a skill gate rather than an age gate: players "can begin using breaking pitches after developing consistent fastball and changeup."
The American Sports Medicine Institute, the research body behind much of this work, is more sceptical of the curveball panic. Its position statement for adolescent pitchers notes that throwing curveballs "has been suggested as a risk factor, but the existing research does not support this concern," and states plainly that "research points to overuse as the principle risk factor." ASMI also publishes the learning order: basic throwing first, then fastball pitching, then changeup pitching.
Little League has published research pointing the same way. Its five-year study with USA Baseball and the University of North Carolina "failed to show an increased risk of arm injury due to breaking pitches, such as curve balls," and found overuse to be the primary cause — which is why Little League has never banned the curveball, and says so explicitly.
Dr. James Andrews, writing on Little League's site, takes the most conservative line of the four. He describes the curveball as a sophisticated pitch that is hard to throw well, and recommends "not throwing curveballs until they shave" — that is, until a player has been through puberty and their bones have matured.
So the honest summary is this. Two of these sources say the evidence does not single out the curveball; two counsel waiting anyway, one by age and one by skill. All four agree on the thing that actually predicts injury: workload and fatigue, not pitch type. A twelve-year-old throwing 110 pitches of nothing but fastballs is in considerably more danger than one who threw forty with a curveball in the mix.
If you want a practical position that no authority would object to, it is the one they share: get the fastball and changeup genuinely consistent first, respect pitch counts and rest days, and add anything else later.
A note on mechanics and pitch lessons
Dr. Andrews makes one further point worth passing on to parents. Poor mechanics contribute to injuries, so working on good mechanics matters — but pitching lessons are themselves additional workload. A weekly lesson on top of two games is a heavier week than it looks on the calendar. Count those throws too.
The same goes for radar guns. Andrews specifically warns against young pitchers chasing velocity, noting that a radar gun in the backyard encourages throwing beyond a safe margin at an age when the elbow ligament is still developing.
Practising them
Grip work does not require a mound. Two players throwing at forty feet, one crouched as a receiver, switching grips every ten throws, is exactly what USA Baseball's own drill prescribes. Warm up properly first, keep the volume modest, and stop at any sign of arm discomfort.
