MLBPA says pitch clock to blame for injuries; league counters

7. I Disagree With MLBPA

There is correlation, but nothing to prove causation.
In fact, since the pace of the game has reached that of the late 70s to 1990, comparing pitching injuries does not correlate. Far fewer injuries, with pitchers burning more innings, where the amount of time between pitches is roughly the same. And, that time period aligns with the refinement of TJ surgery. Very good restorative surgery existed, yet used less often.
I believe the culprit is the emphasis on throwing every pitch hard & focusing on spin rate. Add to that more rigorous weight lifting and you have strength & speed that exceeds soft tissue tolerances.
I think it's much simpler to assign cause to trying to throw a hundred 35 or 40 times a game, and maximizing movement on every pitch, because they don't want pitching to contact anymore.
The very act of modern pitching is more than most human arms can handle.
