In the pine-tar game, the Commissioner’s ruling was that the umpire erred in interpreting the rules when he called Brett out for having used a bat with pine tar that was too high up (on the label), and the home run should thus be reinstated (but the bat confiscated and not being eligible to be used in a game again). The blown call last night was not an error in rule interpretation, but an error in a judgment call (safe or out), which is an entirely different thing. Judgment calls need to be made (and corrected, if other umps had a better view) at the game by the umpires, not by the Commissioner.
The poor judgement in this case, was the umpiring crew's unwillingness to do this. Anyone can make a mistake, a real jerk fails to correct it. Why do managers argue calls if umps will NEVER correct them?
So, Leland should have gone to the ump, stood between the ump and the jumbotron and said, "While I pretend to argue with you, you watch the replay over my shoulder and the pretend that I made such a forceful arguement that you were convinced to appeal the call to the home plate ump. Tell him to over-rule you and call it an out."
Problem solved.
