re: LSU commitment Landon Marceaux was brilliant,

So many individual physiological and biomechanical factors would go into the equation on whether it was acceptable for an individual to throw that many pitches that there is no set age that you would say it is okay for someone to do that. There might never be an age where it is okay for an individual to throw that many pitches.

There are also a lot of in game variables that are impossible to quantify. On an individual basis, not all pitches, innings, situations will lead to a quantifiable basis to say it's okay at "xxxx" time.

It should never happen in high school and I get sick when I see it In college. You won't see it in professional baseball but for a certain number of times a year, but even then it is largely questioned in regards to the long term health effects from that workload.

To answer your question I'd say never unless I'm getting an MLB World Series ring out of it for a player with some quantifiable future in the game past that date.

Since you asked, when do you think it's acceptable?
