crazystengel, I didn't realize until this last post of yours that you've been referring to your 1990 Cleveland juggenaut. I just spent a few minutes looking through your stats, and I think part of the problem is that you have too much pitching on this team - and too much good pitching in particular.
While I don't know your settings, etc, my guess is whenever Sparky wants to put in a reliever on your team, he has too much flexibility - too many options. I mean, you've got the awesome 1990 Tudor - and he's pitched a total of 55 IP through 76 games (147IP in real life). Almost none of your (many) relievers are on pace to match their innings.
In the 6th-8th innings of your games, Sparky has a lot of good pitchers he can put in. It doesn't seem like he's screwing your team here.
Right now, your two specialists are on pace to get in something like 40 games apiece. That's not bad - it means 80 times this season Sparky will bring in a good relief pitcher just to get the platoon advantage, even when he has a wealth of other good pitchers to choose from. My guess is if you were to try this same strategy, but with 250-300 fewer IP (and maybe exchanging a few of your quality IP for mop-up innings), these guys would get more work.
