based on the individual and I'm not a 120 hard pitch count guy at all- but yeah- that's definately a case of abusing a pitcher.
That's how Mississippi was back in the day though- you could also throw Ronnie Richardson from Columbus in there, I already mentioned Bazzell, Kirk Presley from Tupelo- although, urban legend is that he was ruined from pitching in American Legion baseball of all things, and kind of ironically he is coaching the team that once ruined his arm. And then many, many others that I probably couldn't list because of space.
You would hear stuff about guys throwing 165 pitches or something in game one of a doubleheader and then coming back in the second game to get the save- and I'm talking a two-three inning save here.
