The Fastball. When you think about it, the pitcher starts with this pitch and works about one year with this singular pitch. Then, the pitcher learns to place it, then start adding the change/drop/screwball/etc., but maintaining her fastball pitch. But, all the while the pitcher is working on that fastball, to make it faster and place it. And every additional pitch, the pitcher learns, the fastball still needs re-evaluated. This pitch, is the one pitch, that is ultimately worked on the most!
