Oh master of baseball please tell me how you know kids aren’t throwing sliders at 11 and curves at 12. Because it happens at multiple parks every single day.

have you looked at the elbow valgus stress on curveballs compared to fastballs? because curveballs actually have less elbow and shoulder stress

read the study and lmk when you want to discuss

Please tell me oh baseball guru how more kids and more teams mean that the coaching (specifically pitching coaching) is better.

the amount of kids going to private pitching lessons is at an all time high. the coaching is at an all time high. mechanics are better than ever.

I guess you think kids always have great pitching motion.

absolutely not, when fatigued they absolutely have mechanical breakdowns. thats why our teams know the every pitchers average velo and their top velo and we keep the gun on them at all times. if we see 10-12% drop as they become fatigued we pull them.

are you involved at all with you baseball? do you want to discuss all the leading causes of UCL issues? actually backed by science...not just some opinion you pulled out of thin air...if so let me know. i wrote long post in the other thread detailing everything.

go read my post on pages 4 and 5 and get back to me.

If you don’t think that all of that contributes to earlier injuries I don’t know what to tell you.

so you were saying about curveball contributing??? read the study and get back to me if you would like to discuss

ETA there is some debate that maybe they can cause issues in the formarm that can cause issues on the ucl but still up for debate.

overall i agree kids shouldnt be throwing more than about 5 curves or sliders in a weekend and should focus on developing the 4 seem, 2 seem and changeup until about 15 and really focus on hitting spots. I say that in general because many kids dont have the best body control expecially when hitting growth spurts.

#1 cause of arm issues remain

1) trying to throw with high intent with a lack of strength/stability specifically in the chin up and reverse lunge positions

2) strength imbalances especially when combined with fatigue and specifically ER/IR relationship

3) being underprepared for the volume asked upon them

also key indicators are grip strength, reduced ER range of motion, lack of ability to do chin up chest to bar(lack of ability to decelerate), lack of ability to do flat back reverse bear crawls(lack or loss of mobility), lack of ability to hold a reverse lunge position for 3 min (stability), inverted W at footstrike, and aggressive trail leg...oh and loss of grip strength due to systematic fatigue.
