Why we throw a changeup.
Courtesy of my friend Carlos Gomez over at Bullpen Mechanics (check the blogroll), here’s Clay Buchholz throwing a fastball and a changeup:
You will notice that he doesn’t change his delivery whatsoever when throwing both pitches. This is what we’re looking for. Look harder, though, and see how late the changeup (78-79 mph) arrives compared to his fastball (90-93 mph).
That’s just wrong.
