I think it's rather ridiculous to dismiss the inordinately heavy workload and mistreatment of Prior simply because the evidence isn't conclusive. At his age, the amount of high pitch count games, back to back, and going back in after a shoulder injury, was bound to contribute to injury. It's not just three random games. It was something like a 20-game stretch of just ridiculous treatment. Ask yourself this: Why is a 120 pitch count a high pitch count? I'm not sure why you ask this random quesiton that doesn't address what I wrote in my post. I didn't say 120 was some magic cutoff point. It has to do with the fact that pitching is an inherently risky endeavor, the more you do it, the more you open yourself up to injury. It is unlike any other motion in major sports in that it, in and of itself, can end your career. Most major football injuries involve getting hit by somebody else, or trying to avoid getting hit. But pitching is just a guy injuring himself. Young pitchers are especially vulnerable. You can't just give a guy the ball and tell him to pitch his balls off to a modern major league lineup, where a mistake to the slightest hitter can be put in the stands, and ignore limits. 120 is high because it's more than most are used to throwing and more than most throw. 120 pitches means 120 high intensity pitches, but another 50-100 more warm up tosses in pregame and 10 or more in between innings. It is probably possible to build up stamina and avoid the pitfalls of too much work with time, and proper guidance. But jumping right into the big end of the pool, with a manager who routinely rides his pitchers harder than others, and continuing to have a guy throw after already sustaining a shoulder injury, is just asking for more trouble. Mark Prior was a 120-130 inning pitcher from age 19-21, then, at 22, threw 212 regular season innings, and another 23+ postseason innings, many of them in extremely high intensity situations. Absolutely no care was taken to try and limit the wear on his young arm early in that season, and quite obviously very little thought was put into trying to prevent or monitor injuries, considering he landed on his effing should in the middle of a game and was still thrown out there. Dusty Baker treated an extremely valuable organizational asset with absolute reckless abandon, trying to squeeze every possible pitch out of him early and often, and quite obviously contributing to the destruction of his career.
