I believe this 100%.
One prime example was Lucas Giolito, who was topping 100mph in high school. You don’t need to throw 100mph to get high school hitters out. But scouts bring radar guns to high school games, and every high school pitcher knows radar gun readings can translate to scholarships or signing bonuses. It did get both for Giolito, but it also got him a TJ surgery before graduation.
And once on Real Time, when they were discussing the proliferation of travel baseball, the reporters were talking to parents who were trying to find doctors to perform Tommy John surgery on their healthy high school sons. And they wanted it because it reportedly adds a few mph to the radar gun. (The kicker is it doesn’t “add” velocity, but rather for many pitchers it can restore velocity lost to wear and tear. Not the same thing at all.)
