I have the same issue with reliever's endurance. My mop-up guy with an A RD gets tired after 35 pithces the day after the all-star break and only 20 pitches thrown in the last 5 days. I occasionally let this guy in for another inning or two, but I've had pitchers get injured by making them face an extra batter once they hit "red".

If, as others have speculated, being tired does not equal being "out of gas" perhaps there could be two colors for a pitcher's tiredness indicater, like a pink or amber for "getting tired" and the red for "totally spent". This might even be reflected in the rotation where taking a pitcher to the limit requires 4 days rest to be ready again while otherwise he could potentially go on 3 days rest.
