Crap. It just sounds random.

Are you sure you had every pitcher assigned a role? Mike has previously posted that having one guy not assigned a role will make the robo wig-out with everybody.

Also, did you try to change the bullpen settings for each game? If so, did you remember that they are backwards?

I have seen that the pitchers are generall not being managed properly - it wants to assume a 4-man rotation even with 5 starters listed. It seems like robo will use regular staters for about 22-25 bf, and Aces for 26-28 -- in Sr leagues, depending on when he comes to bat. It does really detract from this hobby to not be able to control your pithing strategies to the extent of having your ace just randomly taken out of the game.
