And therein lies "The Secret".
I learned it many, many moons ago, when I used to go to Yankee Stadium every chance I got and would sit in the upper deck and watch the pitchers. I saw that the Yankees' Big Three rotation were doing this and how they were doing it: they were all driving off the lower half of the body, using the legs, the hips and the torso in one continuous motion, creating a nonstop flow of energy all the way up through the shoulders and arms to the fingertips---they were all generating more power behind their pitches and thus throwing harder and faster with less energy, and in the process they were taking a lot of pressure off those extremities. I saw this, and I made a note of it and started working on it on my own, and as I practiced this essential element of good mechanics I found that I was doing the same thing those three pitchers were doing. And because I was a natural, honest-to-gosh sidearmer I found it much easier going.
The whole idea behind "The Secret" is to get the whole body into the action and not just throw with the arm. So the kid needs to work on this, and one of the best ways to get started on it is the so-called "Hershiser" drill which aims at getting the hips fully involved. It requires no special equipment, just a fence or a wall, and it will pay off in the long run. Also, the kid needs to do a lot of throwing---not pitching, just throwing, about 20 to 30 minutes a day, preferably with a good catcher; this is the best way to keep the arm loose and flexible. Something to think about. 8) :baseballpitcher:
