Are you sure it is a true curve ball? There is a pitch that is being taught that resembles a curve that is called a U-change. Even though I am not a proponent of it, it is an effective pitch and acts much like a curve without the torque on the elbow. If it is a true curve then it is a shame that someone would put a kid in position to ruin his arm at such a young age. Coaches need to realize that winng at 11 is not what it should be about. Developing the fundamentals and competing should be the foundation of an 11 year old.
