This is something I never really paid a lot of attention to until this post came along. I have been specializing, so to speak, in 120k theme leagues, and go with a 3 man rotation. I don't know why, but I seem to get less CG's than other managers using the same pitchers. I prefer not to set my PC settings too high, but high enough that there is a reasonable chance they will complete the game. In a save situation, they are almost always pulled for my closer. In a non save situation, they get the CG, most, but not all, of the time.
