Agreed. Umpires make a lot of bad calls, but it is not that easy to be a good umpire. If it were, you'd see better umpiring at the world's highest level of baseball. I don't know how much training it takes (I'd assume just an absurd amount of time in the minors and college), but having the ability to tell whether a ball was in or out of an imaginary box 95% of the time, or accurately determining whether a runner was safe or out on a bang-bang play 90% of the time, is not something I, or many others, could do, even with immense training. I don't mean to pile on. But, I know a lot of guys who go pour through the rules regularly, go to a couple of camps a year, have been doing some form of umpiring for tens of years and still can't manage to work a slowpitch softball game fluidly. I go to little league games in the area and watch a dad who has to fill-in on the bases for one reason or another. Dad comes in, "oh, I know baseball, this shouldn't be hard". And, by the end of the night, his tune is "I never want to do that again." To answer your question funkeltown, I am actually starting the process in January. After 15 years of umpiring, I am going to try this season. I constantly get good reviews at the college level, so I am giving it a try. (Just FYI though, some guys have zero experience before attending the PBUC and if they love the game, they do very well) You have to attend a PBUC for 5 weeks (there are only two of them, pick one). Approx 60 guys attend each of these for a total of around 120 "applicants". After the 5 weeks, you are evaluated and recommended to either be hired or not. Approx 35-40 get recommend, depending upon openings. So 33% roughly. You continue to be evaluated during spring games (split squad b's usually). From there, you are almost certainly assigned to A. Guys typically spend 1 year at A, 2 years at AA, and then AAA until an MLB position becomes available. Non-MLB umpires always have to supplement their income in the offseason.
