I assume what you meant is what is the best pitch that a pitcher can have in his arsenal. I say fastball. It sets up everyother pitch that you have. You can a have a great curve ball but if you cant locate your fastball or its puss then they will sit on the curve only and mash it. A pitcher with a great fastball can get hitters out with a very avg curveball or change up. That is if he can locate it and what I mean by a great fastball is one that can be located. You can change speeds on the fastball and work locations and get guys out all day long without a curve. If the curve was all you needed then velocity would not matter and you could get a stalker real cheap. Velocity Location Fastball equals success. Throw in an average curve and a decent change and there you go. Remember this is the High School Web.
