Everyone picks on the breaking ball as being the main culprit when it is not. What the studies don't show is that almost all "good" pitchers throw a breaking ball of some sort. What they also don't usually show is that the kids getting injured are playing longer seasons, more leagues, and pitching more frequently. ASMI research has even now proven that the highest stress on the arm is the fastball. Yet, you will never show up at any LL game anywhere in the country and hear- "wow, this kid is throwing a lot of fastballs". If they throw a breaking ball however you almost undoubtedly will hear something like- "he shouldn't be throwing breaking balls at that age, he's gonna have all kinds of arm trobles".
The only thing I can tell you is, throwing a FB is at least using the “natural” motion someone would use picking up a rock and trying to kill meat for the table. Its not likely some caveman would try to bonk a squirrel with a breaking rock.
Here’s what I’ve been told most often. There are a lot of ways to throw a breaking ball that use supination or that put a lot of stress on the elbow, and those are the things that frighten many who understand the pitching motion.
Yes, a lot of mistakes can be made throwing FBs too, an some of them can cause problems, but evidently the conventional wisdom says a badly thrown FB does not have the potential danger a badly thrown breaking ball does.
I think you’re wrong about “them” usually not showing that the kids getting injured are playing longer seasons, more leagues, and pitching more frequently. As far as I know, the “national” conversation by Drs and organizations like ASMI, very much incorporates overuse as a bad thing, not good. It may not be true in every case, but believe me, its so far ahead of what was being said even 5 years ago, its amazing. So progress is being mad, but it takes a lot to change the course of a ship as old and massive as the “Ship of Baseball”.

Trust me, I know, I have seen it over and over again. I have also seen kids- a lot of kids, at young ages who don't even throw a breaking ball and have chronic joint pain and ice after every game and no one thinks anything of it. Why? Because, little Johnny isn't throwing a breaking ball- he is fine (or so they think)! One of the hardest throwing pitchers on our HS team doen't even understand the concept of how to even throw a breaking ball and he suffers from chronic elbow pain.
It's not that I am advocating for Li'l Johnny to go out and throw a myriad of breaking balls, don't get me wrong, I am just saying that way too much emphasis is placed on the dangers of throwing breaking balls when in fact, the real problem lies in bad mechanics in general and also in overuse.
I think you’re very likely right about there being less emphasis on bad mechanics than breaking balls as an injury issue. But think of it the same way most people think about velocity and pitcher forecasting. While there are some things that CAN help predict a pitcher’s success, for the most part those things are pretty subjective, except for velocity. While everyone with any baseball knowledge at all understand that pitching depends on many more things than velocity, it’s the only objective thing there is.
What you’re saying about mechanics is pretty much the same thing. Its easy to point to breaking balls , because generally they’re easy to pick out. But if you got 100 coaches of varying expertise and experience, and asked them to look at the same 5 pitchers and pick out any bad mechanics, how many things do you think would be listed? IOW, what is “bad” mechanically, is very subjective, and depends a lot on how the observer was trained. Its very hard to come up with a national definition when there’s so little agreement.
One other thing about breaking balls. I think a compelling reason for not throwing them pre-puberty, is that they’re not necessary for pitching success. A kid who has a decent FB and a good CU, combined with good command, can have enormous success on the small field, and as we’ve seen in the last decade with the proliferation of the CU in the ML, there can be enormous success on the big field as well. So, there’s an option which most would agree is the least “dangerous” for the kids, but just as successful. To me it’s a no-brainer, except for one thing. There aren’t a lot of coaches who a) understand that, b) can teach command, or c) aren’t afraid to call it in a game, and make no mistake, with all the coaches calling pitching now-a-days, they’re the ones calling so many curves.
