Just for the record... is there any clear, conclusive proof that a strong, young pitcher throwing 120 pitches is doing any damage to his equally strong, young arm that throwing 100 pitches would not?
I'm not saying that Robin actually knows anything about this or is making the right or wrong decisions. He has clearly made some bad game decisions. I'm not sure this is one of them.
Somewhere along the line the number 100 became the accepted limit for starting pitchers. I imagine for some the limit would be a smaller number and for some the limit would be a larger number. I think a determination that pitchers are being over pitched needs something more than a general number of pitches to back it up.
