Occasionally, something my son posts on one of his social media sites will catch my eye as being broadly applicable to young players here. That was certainly the case this morning, when he tweeted the following:
"It's a shame how little the change up is being developed and thrown these days. So much emphasis on velocity and gun readings..."
My speculation would be that he'd just watched the umpteenth high school-aged pitcher this month throw an impressive fastball and then show that he either couldn't command his changeup or never threw one when the situation would have been ripe for it.
When you consider for a moment that college recruiters like him are looking first and foremost for pitchers who can step in and contribute right away, demonstrated feel for a changeup can give a recruit a decided advantage over his peers. Pitching coaches know that the heater, alone, won't translate into success at the college level. From their perspective, the pitcher with the reliable changeup is frequently a better alternative than the guy who's starting at Square One with his changeup.
