I agree. What does drive me crazy, though, is when the umpires are inconsistent with the strike zone. If you're going to call just below the knees a strike, I'm ok with that as long as you are doing it consistently. I can't stand it when they seem to make it up as they go along. That I agree is a problem. And, the past 2 years I felt there was a lot of that. In one of the playoff series (I can't recall which one - Cubs-Dodgers maybe?) the umpires at the plate were awful. They were all over the place. That should not happen.
I suspect that machines calling balls and strikes is inevitable. They will leave an umpire back there for calling plays at the plate, deciding if a ball was tipped, and that sort of thing, but I suspect at some point in the next 5 to 10 years you're going to see balls and strikes called by a computer who follows a chart. And, I think that will be a loss.
Baseball, more than any of the other sports, is a form of entertainment unto itself. It's idiosyncrasies and imperfections are part of what makes the game what it is. Referees in football, when they do their job right, should be almost invisible. But, umpires are part of a baseball game. The theatrics with which they call balls and strikes and plays at the plate, the arguments with them, etc. That is all part of baseball. At least, it always has been, and I think it's part of the game that fans have traditionally enjoyed. But, times are changing. Baseball games are venues for people with short attention spans who can't focus on what is actually happening on the field for 9 (or more) innings. There are still die hard fans but they are, in most cities, overwhelmed by the causal fan who uses it as a night out to do something different and spends more time checking out the beer garden than the game itself. Society has changed and the game as started to change with it. Arguing with the umpires is a thing of the past, mostly. It's really a matter of time before the human element in officiating is either gone or largely mitigated, much more than it currently is.
A few weeks ago, Mike Francesca was on the fan saying they should speed up games by changing the rules to 2 strikes for an out and 3 balls for a walk. I think that is nuts, but he didn't seem to think it would be any big deal and people would get used to it and accept it. I don't think anything nearly that radical would every happen, but I'm amazed it was suggested so cavalierly. Of course, Francesca is a blowhard who says stuff just to keep people tuned in, so hard to take it too seriously, but I was surprised it was suggested at all.
