Fatigue & Resting Players

BaseHit players experience two types of fatigue: day-to-day (short-term) fatigue and seasonal (long-term) fatigue.

Why does fatigue matter?

Players will begin to experience performance penalties when they are tired and increase those penalties (max. 20% penalty) until they are exhausted.
Exhausted players cannot start games, and exhausted pitchers will be removed from the game as soon as possible.
All skills are subject to performance penalties when a player is tired, except for EN (endurance) and SY (specialty).

Fatigue status

Each player has a current and maximum endurance (EN) - when a player is fully rested, these values are the same. A player's fatigue status reflects how rested they are as function of current vs. maximum endurance. The levels are as follows:

Rested (>95% EN)
Good (75-95% EN)
OK (50-75% EN)
Tired (25-50% EN)
Fatigued (0-25% EN)
Exhausted = nothing in the tank.

Day-to-day fatigue

Day-to-day fatigue occurs when players play without a day off.

Position players generally recover well after a day off, while pitchers may need more rest.
Players experience fatigue when they play, shown as reduced current EN.
Players rest when they don't play, shown as increased current EN.
Players with higher max EN will fatigue more slowly than players with lower EN.

Seasonal fatigue

Seasonal fatigue is the overall wear-and-tear of the baseball season.

A player's endurance determines how much they can push themselves before experiencing adverse effects.
Position players with high EN can play almost every day without adverse effects, while players with low EN can't play as many games at full strength.
Season fatigue temporarily lowers a player's effective maximum fatigue level, which reduces the rate of recovery for players on off-days.
Resting a player can reduce or eliminate season fatigue and restore a player to maximum fatigue level.
If a player doesn't regain as much EN as expected, they may be suffering from season fatigue.
Note: Using designated hitters (DH) causes less potential season fatigue than playing a position. Toggle your use of designated hitters to rest players with low endurance.

How quickly do players fatigue?

All position players fatigue when they play, with catchers fatiguing faster than players at other positions, and designated hitters fatiguing slower.
Pitchers fatigue based on their pitch count, losing about one point of endurance for every two pitches. Example: a pitcher with 50 endurance can throw 100 pitches before becoming exhausted and being taken out of the game.

How quickly do players recover?

Players will recover current endurance at a rate of about 1/4 of their maximum endurance per game of rest.
This recovery rate gradually decreases as players accumulate season fatigue.

How do I rest my players?

Manually adjust your roster to ensure how much a player plays.
Platoon your players by changing your lineups against right-handed (RHP) and left-handed (LHP) pitchers. Rest players by using right-handed hitters against left-handed pitchers and left-handed hitters against right-handed pitchers.
Set your manager settings to automatically substitute players when they fall below a certain fatigue threshold. Adjust the "rest player" sliders to rest players sooner when they are tired. Players can rest in AAA, where they are guaranteed not to play.
