I have long wondered about the auto-rest settings for your bullpen. For example, if your closer has an auto-rest of 95 and is sitting in the 70's, should you move the preferred next in line to closer? Second question would be, is it necessary to make any fatigue-based changes to your bullpen if there is an auto-rest function? Does the sim-engine just make the choice for you? Do you other, better coaches, find this to be suitable for your teams?

You can change your bullpen every game if you want to but it's going to be a lot of work. all depends on how much time you want to spend on your team. It's not necessary to fine tune your bullpen all the time but it's probably worth a slight advantage to always have it exactly the way you want it.

I almost never touch my bullpen settings in-season unless there is a fatigue situation or I want to rest some guys for the postseason down the stretch.

Thanks for the advice. I had been switching them up like crazy, but I'm going to try leaving them for a bit.   

Hi artie40

Although this doesn't answer your specific questions, I thought this advice might help you.

Stretch your starters
The best method I have used to fight bullpen fatigue is to stretch starters with high IP and IP per game.  It might seem totally obvious, but you would be surprised at how many managers let a long man come in late in a close game when it doesn't necessarily need to happen.

Often throughout the season, starters will be pulled early and build up a lot of unused innings.  If I see my better set up guys are fatigued, I will significantly increase the starters pitch count and worry about his next start when it comes.   Usually another starter can be bumped up and take the 'stretched' starter's spot when his turn comes up again.

If you do this, make sure you are not stretching starters that have a low IP per game, and make sure to dial him back down once your bullpen recovers.

You can crush people in this game if you keep a close eye on your pen and make sure you have your mean set up guy in to protect one run leads instead of some rubber arm guy you drafted (or called up) to eat innings.
