My DD was exactly like that last year. This year her Drop ball actully drops most of the time, there is an actual difference in th speed of her change up and the rise ball is the one that looks like a change up thrown over the catchers head.S
My 12U DD currently has three pitches. Drop (that doesn't really drop), Change (that isn't much different from the drop that doesn't drop), and the "What the hell was that?".
My friend's 12U DD has, according to him, seven pitches. Remarkably, they all look like my DD's third pitch. Go figure.
I'm hoping for my 12U to have 4 someday: drop, rise, curve, change.
The first pitch my DD learned was a fastball, so I am always curious what happens when a pitcher has multiple pitches and one of them is NOT a fastball. Did she never learn how to throw a fastball? Did she forget how to throw one? Does she just choose never to throw it, or did she renamed it something else so people will not think she is lame?
Speaking for myself, I never taught my DD a fastball. I taught her a drop that she uses as her fastball.
