To find an emergency starter we just go down your pen looking for the first guy listed who started a game that week in the majors. If no one in the pen has a start available we go down the list looking for the top guy listed who pitched at least 3 innings that week in the majors. Also, you can only use 8 pitchers, and up to 16 hitters, in a single game. So, if you are using your 8th pitcher he will not be hooked when he reaches his hook number. If he does run out of innings we will bring in PAAA, and then he will pitch till the game is over.
Starters face a fatigue factor .
They tend to pitch a little worse as the game goes on. A pitcher who is pitching longer in Scoresheet than his average major league appearance that week will suffer more of a fatigue factor. Pitchers on the short reliever list cannot start in Scoresheet unless they become starters in the majors. Minimum hook for a starter is 3.0. This 'carry over of unused starts' happens only if one of your starting pitchers started twice some week in the majors, but was only needed to start once for you.
