I completely agree with this philosophy, personally, though I believe when it was last brought up Tim mentioned there had been research done to suggest that an innings count can be just as detrimental than pitch count, regardless of how many pitches are being thrown each time out. I don't know, I approve of shutting him down and preserving their star pitcher, especially when you have a rotation behind him talented enough to compete in the playoffs without him... but I've always thought that innings were less important so long as the pitch count stays down, personally.
