re: How long is Paul Skenes arm going to hold up?

Many factors contributing to the arm injury epidemic but you can't deny the emphasis on high velo and high spin rate the past 12 years or so has greatly contributed to this. It has now filtered down to the sub High school levels because this is what scouts look for. This is what produces your national recruiting rankings.

Ita not the only factor by far but the number of UCL injuries has sky rocketed. At lower levels I do believe many kids are chasing velo before their body gains enough strength to handle the load.

You also see kids at 11yo throwing a ton of breaking balls. I see it every weekend.
