Our 2019 just turned 17, will head to college at 18. My observations with college coaches is that they don't consider age, only how the player can fill their specific team's needs, and whether he can be admitted. There is such a Gaussian curve on maturation that age is probably not as good an indicator on "projectability" as how physically mature a boy is. A baby face chunky kid could be 14 or 18, and eventually will be physically mature. This is way beyond the bandwidth of most coaches, IMO, unless it is a lanky pitcher. Focus on what you can control. Our son wanted to reclassify but we thought it was not important. Not sure yet where he will end up but his focus has been on conditioning, baseball, and studying for tests, and not on his age.
