You're assuming that he's more likely to be injured on his 90th pitch than he is on his 50th pitch. Do you have any tangible proof that this is true? Or would it just be a "feel good" moment for you if he was injured in the 6th inning of a 3-2 game as opposed to the 6th inning of a 9-0 game?
I am of the belief - and no, no tangible proof - that a player is more likely to get injured the more fatigued he is. I know for certain that there is in-game fatigue and that he is more fatigued on his 90th pitch than on his 50th, so I believe that he is more likely to get injured on his 90th pitch than his 50th.
Even if - for the sake of discussion because I think you agree with me that he's more likely to get injured on pitch 90 than 50 - the likelihood of injury remains the same regardless of fatigue, I am very willing to sacrifice IP from my low health starter in blowouts if it means he is more likely to be healthy for the post-season.
Put it this way, if he throws every 5th day for me and logs 100 pitches every time, he has a X% chance of being injured at some point in the season. If he throws every 5th day and logs 100 pitches 4 times out of 5, but only has to be called on for 75 pitches that 5th time, his chance of being injured is something less than X%.
Some managers, myself included, might value that reduced likelihood of injury. If you're not one of them, you'd be free to leave the "remove pitcher if up X runs in X inning" box unchecked, just like with player rest or defensive replacements.
