Year-round baseball
Kids competing without rest, with no real time to recover. The #1 risk factor according to Dr. James Andrews.
PILLAR 3 · THE TA METHOD
Arm Shield
Your son only gets one throwing arm. Here's what the science says about protecting it.
The one stat every parent needs to know
36:1
36 to 1. That's not a margin — it's an alarm.
Before we talk routines, let's talk about the number that changes everything. Research from the American Sports Medicine Institute (ASMI) — the leading authority on youth baseball injuries — found that adolescent pitchers who end up needing shoulder or elbow surgery were 36 times more likely to have routinely pitched through arm fatigue, compared to healthy teammates.
And the #1 risk factor, according to Dr. James Andrews (the surgeon behind more Tommy John surgeries than anyone in baseball history), isn't mechanics or pitch type. It's year-round baseball — kids who aren't just throwing without rest, but competing without rest, with no real time to recover. Playing on more than one team at the same time, where one team's pitch counts don't talk to the other's, is the second-biggest risk factor.
This is exactly what Arm Shield exists to prevent.
The 3 real risk factors
The 3 real risk factors (and why showcases are dangerous)
ASMI research points to three main factors: overuse (number of pitches in a game, season, and year), poor mechanics, and poor physical conditioning. Of the three, pitch volume combined with inadequate rest is the biggest contributor.
Off-season showcases
Dangerous when the arm isn't in game-ready shape. The common mistake: overthrowing to impress the radar gun instead of treating it like any other game for pitch-count purposes.
Pitcher-catcher combo
A player shouldn't be both the pitcher and the catcher on the same team: it's the single heaviest arm-load combination in youth baseball.

Golden rule for parents: you're the one keeping the real count — not just the team scorekeeper — because if your son plays on two leagues or teams at once, nobody else is adding up the combined total.
Warm-up
The non-negotiable before throwing
An effective warm-up should raise heart rate gradually, using dynamic — not static — stretching, to move the body from rest into activity. The sequence we recommend at TA Performance:
- 1
Light jog
5-8 minutes to build general circulation.
- 2
Arm circles
Arm and shoulder, progressive, small to large.
- 3
Scapular mobility
Band pull-aparts, no-money drills: activates the muscles that stabilize the shoulder before load.
- 4
Throwing progression
Start short and easy, build distance and intensity gradually; never go “cold” into max effort.
Throwing without this process is one of the fastest ways to stack up unnecessary microtrauma.
After throwing
What the science says TODAY (and it's not just ice anymore)
Here's an important shift many old-school parents don't know about. The iconic image of a pitcher with an ice pack on his shoulder isn't necessarily the best answer anymore. If what you're feeling is general soreness (normal microtrauma from the effort), the body repairs it on its own by sending blood to the area — and what helps more is active recovery: an easy jog, stationary bike, or swimming, which brings oxygenated blood to the fatigued muscle instead of restricting it with ice.
That said — there should never be extreme, sharp pain or loss of mobility after throwing. If that happens, it's a deeper issue and needs medical evaluation, not ice or at-home rest.
Warning signs
When to stop TODAY
This is the most important part of the entire guide. If your son shows any of these signs, stop throwing that same day, no exceptions:
- Pain during the throw (not after) — this is never normal
- Sudden loss of velocity or control with no clear reason
- Mechanics changing to “hide” discomfort (dropped arm slot, shorter stride)
- Complaints of a “dead arm” that don't improve with a normal day of rest
- Pain on the inside of the elbow (UCL area) — the classic Tommy John warning sign
Throwing mechanics deteriorate when a player is fatigued — hip-to-shoulder separation and trunk tilt break down, and that's exactly what multiplies injury risk 36 times over. Most of the time, your son won't tell you “it hurts” — he'll tell you “I'm fine” because he wants to keep playing. That's why the parent has to observe, not just ask.
The parent's role
How to ask without pressuring
Don't ask “can you pitch today?” — that question invites an automatic “yes” because the kid wants to play. Ask instead:
“How does your arm feel today, on a scale of 1 to 10?”
“Is anything different compared to yesterday?”
“Did you feel anything weird in your elbow or shoulder during the game?”
And the hardest rule to actually follow: if a local “healer,” a league coach, or even your son's own desire to play conflicts with real pain — the arm always wins. A lost season is recoverable. A torn UCL at 14 isn't always.
When to seek medical evaluation (not a coach, not a “healer”)
See a sports medicine doctor or specialized physical therapist if there's: pain that persists beyond 2-3 days of normal rest, pain at rest (not throwing), visible swelling, tingling or numbness in the hand, or any sharp/acute pain during a throw.
