Re: Knowing how to pitch
Good question, but I think easily answered: Half of the game is 90% mental.
OK, in reality though, there is no perfect way to pitch. Take Greg Maddux, he is one of the "really knows how to pitch" type of guys. The way you pitch changes every AB. If it were in a book, hitters would read it and know how the pitcher thinks. If it was always consistant, the hitters would know. But, it is a huge mental part of the game; "Knowing how to pitch."
I'm going out on a limb saying that I think Randy Johnson is going to struggle because he fired in 95 mph fastballs, and the filthiest sliders to get guys out. Now he doesn't have either weapon as well as he did before. Our favorite guy Joe Morgan said that RJ has always known how to pitch, but I am going to disagree. He has lost velocity and now isn't getting guys out, because he doesn't know how to out-witt these guys yet.
