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?
My DD was taught a peel drop as her fastball. We use the term fastball and drop ball interchangeably.
The reality is its the pitch that's faster than her change up and goes downward with heavy topspin when she throws it correctly. When she throws it incorrectly she gets bullet spin on it. But hey she's 11 what are you gonna do.
