A lot of my pitchers in AA and AAA are stuck at 0(0).  For the most part, they've got staminas of about 70-78, with a few exceptions.  I've tried resting them and it doesn't seem to help.  I've got one guy with a 70 stamina who hasn't pitched in 8 games and he's still stuck at 0(0).  Admittedly, because all of my pitchers aren't pitching well and I've had a bunch get injured, he's had to pitch a lot.  He pitched all 3 games on Christmas, but that was still 8 games ago.  Shouldn't he be recovering by now?  How long does it take to recover from overuse?

All depends on how far into the "negative" you drove them.  They keep getting more fatigued if you keep pitching them, it just doesn't show anything below 0.  The guy you specifically referred to has a DUR of 30 (meaning he's going to recover maybe 25% or so a game) - he was at 0 and then pitched 4 of the next 5 cycles (including the 3 straight you mentioned) - I'm sure he's done for a quite a while.

Tryout camp pitchers.  Sign them and rest your fatigued pitchers. 

Thanks.  Unfortunately, I took over a team full of hugely over-paid albatrosses and accepted the salary the game suggested.  Now, I've got one of the highest paid teams in the league along with one of the worst records.  I can't even promote players out of the rookie league because it would put my salary over the limit, so I can't afford to take on any other players.  Guess I'll just have to wait this out for a wasted couple of seasons.

Well, that's bad.  IF any of those 0(0) guys are a legit prospects, put them on inactive.    Blow up the scrubs because guys pitching at 0(0) will eventually get injured.
