The MLB Umpires Media Guide is exactly what it sounds like. It is a
PR book that lists all the biographies of the current umpires, notable games (perfect games, no-hitters, etc) and who was on the plate, Roster of umpires from the beginning of baseball, all MLB parks' ground rules, general duties and responsiblities of the umpires, etc. All kinds of useless information to anyone except a broadcaster or an Amateur Baseball Umpire. And for us it is still useless, but we are entertained.
