SP/RP usage question

[UrbanShockers]

I have Bob Johnson as one of several guys I rotate for use as my fourth starter. In the semis, he pitcher two innings in game 1 (and none in game two). I'd like to set him as my starter for game 4, but wonder if he will be tired, or more vulnerable to becoming tired, that the alternative (Red Faber, who did not pitch in either game 1 or 2).

If anyone knows the answer, or a good guess, I'd appreciate your thoughts.

He should be rested & ready to go.
