Rather than "notify" the commissioner, could you just ask, diplomatically, about the health of this umpire? Was this umpire just having 1 bad day or is this a constant? What about his partner in game 2? I, for one, would be VERY distracted during the game worrying about my partner. I know nothing about his medical condition, but "dying with his boots on" is not something that anyone needs to witness. How many of us had our eyes on catchers during intense heat? If we can concern ourselves with the health of young players, ought we not step up in this situation? Obviously, this man is aware of his situation and chooses to be out on the field. But does he comprehend his impact on the game itself? If getting him to umpire lower level games would solve this problem, then he can continue to "enjoy" himself and will (hopefully) come to realize that there is a reason for it. Would I work with this umpire? Absolutely!! My pregame would be along the lines " You've got balls and strikes and I have EVERYTHING else. I need you well enough to do another game together some day." Umpiring is something we do, being aware that we are human beings responsible for each other is something we ARE. I am not in any position to judge this man, nor would I. If 2 hours of my life is the price I need to pay, so be it.
