If we truly want to save adolescent arms,
we have to go far beyond pitch count.
Pitch count is an arbitrary number.
It tells us nothing about:
• how efficient the pitcher was
• how much stress the arm absorbed
• whether the athlete was breaking down on the mound
That’s why arms keep getting injured while following the rules.
What we should be measuring is:
• Efficiency (OP10) — how many outs were earned per pitch
• Pre-game strength & movement
• In-game fatigue changes
• Post-game recovery markers
These tests are:
✔️ Simple
✔️ Fast
✔️ Inexpensive
✔️ Easy to implement at any level
And they would save thousands of arms every year.
Pitch count is a starting point —
not a safety system.
Efficiency + objective testing is how we protect pitchers.
