What is Short Arming in Youth Baseball? (And How to Fix It for Good)
If you’ve ever watched your kid throw and thought, “That throw looks tight and stiff,” you might be seeing something called short arming — and you’re not alone. It’s one of the most common mechanical issues in youth baseball, and it can seriously limit a player’s ability to throw hard, throw accurately, and stay healthy.
In this article, we’ll break down what short arming is, why it happens, and most importantly — how to fix it long-term with proven drills, strength routines, and smart coaching.
What is Short Arming in Youth Baseball?
Short arming refers to a throwing motion where the player keeps their arm tight and bent instead of extending fully during the throw. The arm doesn’t reach back into a full throwing position — almost like a catcher’s quick toss instead of a pitcher’s smooth, full delivery.
This limits arm speed, reduces power, and can lead to arm injuries over time.
Why Does Short Arming Happen?
Understanding the cause is the first step toward fixing it. Players may short arm for a number of reasons:
-
Fear of pain or previous injury
-
Weak shoulder or core muscles
-
Trying to throw too fast too soon
-
Incorrect mechanics or lack of instruction
-
Position habits (common with catchers and infielders)
How to Fix Short Arming in Baseball — Long Term Solutions
Correcting short arming isn’t a one-day fix. It takes time, proper training, and consistent coaching. Here’s a step-by-step breakdown of how to fix short arming in youth baseball:
1. Teach Proper Throwing Mechanics
Start with the basics. Use slow-motion video to show kids what a good throwing motion looks like. Teach the “T position,” full arm extension, and proper rotation.
2. Strengthen the Arm and Shoulder
A weak arm often leads to mechanical shortcuts. Build strength with:
-
Long toss programs
-
Resistance band shoulder workouts
-
Scapular stability and rotator cuff exercises
3. Use Targeted Throwing Drills
The right drills build proper movement patterns. Try these:
-
Figure 8 Throws – For rhythm and fluidity
-
Wall Takeaway Drills – To fix early arm positioning
-
Plyo Ball Reverse Throws – Builds healthy arm path and speed
4. Slow the Game Down
Young players often rush their throws, especially under pressure. Practice with intent, not panic. Use short-distance throwing progressions to reinforce correct movement.
5. Be Consistent and Patient
Fixing short arming is a process. Make throwing form a regular focus in practice, not just something you check once a season.
Bonus: Signs Your Kid Might Be Short Arming
Look for these signs during warmups or games:
-
Elbow stays too close to the body during the throw
-
Arm doesn’t extend fully behind the player
-
Decreased throwing velocity
-
Complaints of shoulder tightness or arm fatigue
