🔥 The Velocity Lottery

The truth about velocity is this: there’s many pitchers who throw hard but have no idea why.
And to attribute their velocity to a cookie cutter throwing program; or their arm slot; or a mechanics tweak; would be foolish.
Bigliani et al found that 67% of pro pitchers had a positive sulcus sign in their throwing shoulder, and of those 67%, a full 89% had it in their NON throwing shoulder as well; meaning the trait wasn’t acquired, it was hereditary
Furthermore, in a study of 1400 pro pitchers, every pitcher without exception were found to have in excess of 190 degrees total ROM in both their throwing AND non throwing shoulder.
These are just some of the genetic factors that allow some guys to throw hard “just because”
The more pitchers I’ve observed, stretched and measured, it becomes abundantly clear the research is correct:
Some athletes are greatly predisposed to throw hard
Others aren't
Frankly, most of those who come to our facility are the "aren't" ones. And that’s why training has to be maximized, because it's one thing to babysit a genetic star who's going to be drafted, or an established MLB pitcher- its another story all together to train the 79mph 5'9" high school senior.
And that’s what so many young pitchers miss: while genetics is a massive piece, MOST successful pitchers are also tall/big/strong/athletic; which other than height, IS trainable
Many kids have potential to climb, but they need individualized throwing programs not cookie cutter; they need to go from weak to strong; and go from unathletic to explosive
And that’s where their breakthrough will come from
