Pitcher Fatigue Options

The parameters that control how pitchers get tired and how long they need to rest are accessible from the Options->Pitcher Fatigue Options menu item. 

These options are described in detail below:

  • OBP fatigue penalty per batter: This option specifies how much of a bonus to apply to a batter's on base percentage when a pitcher is fatigued.  The bonus increases by the value of this option for each  additional batter beyond the pitcher's limit.  This option must be between 0-999 and a value of 1 is equivalent to 0.1%.  For example, a value of 20 represents a 2% increase in a batter's on base percentage for each batter beyond the pitcher's limit.
  • SO fatigue penalty per batter: This option specifies how much to decrease the ratio between strikeouts and outs when a pitcher is fatigued.  The ration decreases by the value of this option for each additional batter beyond the pitcher's limit.  This option must be between 0-999 and a value of 1 is equivalent to 0.1%.  For example, a value of 10 represents a 1% decrease in the likely hood that an out will be a strikeout for each batter beyond the pitcher's limit.  This parameter has no affect on the batter's on base percentage, but it does reduce the the probability that, when a batter gets out, it will be a strikeout (as opposed to all other types of outs).
  • Maximum fatigue penalty: The maximum bonus that will be applied to a batter's on base percentage of strikeout ration when a pitcher is fatigued (see How Ratings Ratings are Calculated). As a tired pitcher faces additional batters, the bonus will never exceed the value of this option.  This option must be between 0-999 and a value of 1 is equivalent to 0.1%.  For example, a value of 100 represents a maximum 10% bonus applied to a batter's on base percentage or a maximum 10% decrease in the strikeout/out ratio.
  • Starter's fatigue deduction factor when rested: This option specifies how much rest a starting pitcher will be given when granted a day off.  Specifically, the value of this option represents a percentage of a pitcher's durability, and this will be used to determine the number of batters faced that will be deducted from a pitcher's fatigue per day of rest.  This option must be between 0-2999 and a value of 1 is equivalent to 0.1%.  For example, if the value is 200 and the starter's durability is 30, that starter's fatigue will be reduced by 5 batters faced (30 durability * 20%) per day off of rest.  At 200, it will typically take five days for a starter to be completely rested.  As a result, a value of 200 will lead to a five-man rotation and a value of 250 will result in a 4-man rotation.
  • Reliever's fatigue deduction factor when rested: This option specifies how much rest a reliever will be given when granted a day off.  Specifically, the value of this option represents a percentage of a pitcher's durability, and this will be used to determine the number of batters faced that will be deducted from a pitcher's fatigue per day of rest.  This option must be between 0-2999 and a value of 1 is equivalent to 0.1%.  For example, if the value is 600 and the reliever's durability is 10, that reliever's fatigue will be reduced by 6 batters faced (10 durability * 60%) per day off of rest.  A value of 500 will typically limit a reliever to pitching every other day and a value of 1000 will allow the reliever to pitch every day, if needed.
  • Chance for consecutive relief appearances: This options specifies the chance that a reliever will be able to pitch in consecutive appearances.  The larger this option the more likely a reliever will be rested and able to pitch the day after an appearance.  This options provides an excellent way to control reliever usage. Lowering this option will decrease the number of appearances for relievers and therefore more evenly spread appearances across all pitchers in a bullpen. This option must be between 0-999 and a value of 1 is equivalent to 0.1%.  For example, a value of 250 represents a 25% chance that a reliever will be rested and able to pitch the day after an appearance.  The default value is optimized for a 40 man roster with an ample pitching staff.  For libraries with small pitching staffs, this option should be increased.
  • Minimum innings before starter gets tired: This option specifies how many innings a starter can pitch without getting tired, regardless of the number of batters they have faced.  This option makes it possible to start a pitcher that has a low durability rating because they pitched mostly in relief in real-life.  The default is 5, which specifies that a pitcher will not get fatigued until after they have pitched five innings.
  • Minimum durability value: This option specifies the smallest possible durability rating allowed.
  • Starter's maximum durability bonus: When the number of batter's faced by a pitcher exceeds their durability rating (see How Ratings Ratings are Calculated), they are susceptible to becoming fatigued.  When a pitcher becomes fatigued their performance suffers.   Exactly how many batters a pitcher can face beyond their durability rating before they become fatigued varies from game to game, and from pitcher to pitcher.  This options specifies the range of this variation for starting pitchers.  For example, by setting this option to 5 starting pitchers will be able to face from 0 to 5 additional batters before getting fatigued.
  • Reliever's maximum durability bonus: When the number of batter's faced by a pitcher exceeds their durability rating (see How Ratings Ratings are Calculated), they are susceptible to becoming fatigued.  When a pitcher becomes fatigued their performance suffers.   Exactly how many batters a pitcher can face beyond their durability rating before they become fatigued varies from game to game, and from pitcher to pitcher.  This options specifies the range of this variation for relief pitchers.  For example, by setting this option to 3 relief pitchers will be able to face from 0 to 3 additional batters before getting fatigued.
