Baseball players generally suffer from two types of fatigue: day-to-day (short-term) fatigue, and the seasonal (long-term) fatigue.
Rested > Good > OK > Tired > Fatigued > Exhausted
Tired and Fatigued players will suffer gradually increasing performance penalties, and Exhausted players cannot play.
Fatigue is a factor of a player's Endurance. Each player has a current and maximum endurance - when a player is fully rested these values will be the same, ex. 60/60.
All players lose a similar number of Endurance points when playing, but a player with higher overall Endurance will fatigue proportionally more slowly than players with lower overall Endurance.
Example:
Player A: EN = 80/80 Fatigue = 100% (fully rested)
Player B: EN = 40/40 Fatigue = 100% (fully rested)
Both play a game and tire similar amounts
Player A: 78/80 = 97.5% rested
Player B: 38/40 = 95% rested
As you can see, bothBoth players suffered the same endurance loss, but because Player A has a greater overall Endurance rating, the effective fatigue he suffers is less than the less-durable Player B.

InSeason allFatigue cases,(see players do not suffer fatigue penalties until their fatigue falls below 50%. At 50%, players begin a steady decline in their ratings until 0%, where their ratings are reduced by 20% (10% for pitchers). Once a player’s endurance falls below 0% there is a more accelerated decline. Position players who reach -50% fatigue would be playing with their ratings reduced by 60% and there would be a 30% reduction for pitchers. All skills are effected by fatigue with the exception of EN and SY.below).
There are a few ways keep your players rested, aside from manually adjusting lineups between games.

Twenty games into the season, he's played in all 20 games. This is over the 75% limit, but since it's only been 20 games, the impact will be small (if not non-existent).

However, if he played in 20 of his team's next 40 games, bringing him to 100 out of 120 games played, his season fatigue will go down.

Note: Each game at DH causes less potential season fatigue than when playing a position. Toggle your use of designated hitters to extend low-endurance players.
Whereas day-to-day fatigue reduces a player's current Endurance, season fatigue impacts two things:
The formula for season fatigue is complex, but takes into account a player's usage as compared to how far into the season it is. Players can be used lightly at the beginning of the season and play hard at the end to avoid suffering season fatigue. Similarly, players can be rested at the end of the season to get themselves a little extra rest (and less season fatigue) before the playoffs.
