It starts to get better at age 23 and turns the corner in the mid 20s. So what's the rush with a kid arm? It's helping no one to elevate a kid to the majors and have him get his clock cleaned.
What would be useful is to find what separates successful young pitchers from the larger group of batting tees. My guess is it boils down to control and physical maturity more than raw stuff, but it would be instructive to put some organized research into it.
Well, maybe these guys who struggled at 20-21-22 were ready to pitch at 23 becuase of what they learned at those other ages. Its all a learning curve, and you are going to learn more, for the most part, by struggling. The guys that are breaking in at those ages, are for the most part, the most talented guys, and likewise, they got away with a lot more in the minor leagues than guys with lesser stuff. So when they get to the majors, they aren't getting away with it as much, and they have to then make adjustments that lesser stuff guys were making in A+ at the same age as they are now making in the majors. Thats just my opinion on it anyways.
