Reading this, I got the impression that the kid is just throwing batting practice—and a pitcher who throws batting practice is supposed to get racked up like that, because the batters are practicing hitting. But, if the kid is not throwing batting practice, he needs to take a good look at what he’s doing on the mound, in order that he may keep the batters from hitting.
When I was a little snip, eleven, twelve years old, I came up on a drill that was more than just that—it was a terrific workout and a lot of fun, and I continued to do it well into the years that I was pitching. Your kid is probably doing this at the 46-foot pitching distance, and he can continue to do this when he switches to the 60’6" (regulation) distance. And here it is: I would get a catcher—there’s nothing like having a real live catcher with a mitt for this—and either he would mark off a pitcher’s rubber and a home plate (we did this at 60’6" all the time), or if we could get to a playing field that wasn’t being used I would take the mound and he would position himself behind the plate. (The problem with the chalk marks is that they are too easily scuffed into oblivion, by the way.) And we would play a little game we called “ball and strike”: the catcher would position his mitt in various spots, high, low, inside, outside, every which way but standing on his head (:lol:), and I would concentrate on getting the ball smack-dab into the pocket of the mitt. I did this with all my pitches, at different speeds, using the crossfire (I was a natural sidearmer), and what a nice satisfying feeling it was when the ball hit its intended target! From time to time we would have someone stand in the batter’s box, on either side, so I could work on really zeroing in on the strike zone—which in my day was much bigger than it is now, and the pitcher’s mound was a few inches higher. I can tell you, there is no better way to work on one’s control and sharpen it up than this!
At this stage of the game, your kid doesn’t need any more pitches than a decent fast ball and a good changeup, and as far as the latter is concerned I would recommend the palm ball. This was the first change I picked up, and it’s an easy one to throw and control because you throw it with the same motion and the same arm speed as you do a fast ball. You grip it with all four fingers on top of the ball and the thumb underneath for support and you grip it well back in the palm of the hand-----but don’t grip it too tightly, because you do NOT want to squeeze the juice out of the ball!
This is how I started out—only, because I didn’t have a fast ball to speak of and I knew I would never be a rip-roarin’ fireballer like Feller or Raschi or Verlander, to name three, I had to go to the breaking stuff early on, and so I began with a nice little curve ball that came attached to my sidearm delivery, and I went from there, in easy stages. I think this will help get things squared away. 8)
