When all fans of baseball are against you and want the gutty little Cubs to win, you will never get the benefit of the doubt or sympathy.
Most archaic system in the world with regards to umpires.
Like any official in any sport, they are considered sancrosanct and cannot be challenged because they allegedly call it square. Seeing as how stats show that some umpires are either selectively bad or playing favorites, but no official can honestly say they don't notice uniforms or who is pitching or hitting. Hernandez is just a lousy ump, Jim Joyce believes his own press clippings from 2008 and Laz Dias has to be either vision or mentally challenged. I can't think of an ump since the days of Doug Harvey who is considered even mediocre. Byrnes call for robot umps makes more sense each day.
