If a pitcher appears in relief, how long does he have to rest before he is eligible to start a game?

Thanks!

He can start the very next game.

Would he be fatigued?

I just ran this experiment. In the 60s game Bob Buhl pitched 2 innings of relief in game 3 of a series. In the next series I used him to start the first game and he was an F9.
