What a crock. No umpire is making up his own strike zone. He's simply calling what he sees. The one example cited for me today was the last Rays better in the 1st inning. Houck through a pitch that crossed the bottom line of that invisible rectangle we all see so precisely on our TV screens but which no one on the field of play sees. I looked it up on mlb.com and agree it should have been called a strike--but was in fact called a ball. But then that same Rays hitter grounded out. So, basically, it just caused Houck to throw another pitch.
And once again, whether or not we agree with the calls on balls and strikes, its abundantly clear that the outcome of this game will be the result of the players on the field and not the freaking umpires. Rare is the the MLB game today in which anyone can rightfully claim the outcome was decided by bad calls by the umpires. What we see with respect to that rectangle on our TV screens--that is, those calls we disagree with--is just nuisance value. The balls and strikes called by the home plate umpires are well within the parameters of what is needed.
From the very beginnings of baseball, what we have always wanted the umpires to do and be is, for lack of a better word, officious. We want them present, decisive, loud, and visible. Make the call and make sure people know what you called.
Baseball is a human endeavor and should be officiated by humans, not machines. I hasten to add, however, there seems to be no limit on the use of computers to analyze and predict where balls will be hit, pitchers' tendencies, etc. Plus I'm pretty sure ball and strike calls--which we fans can now find recorded on mlb.com--are reviewed by the umpires as well as MLB officials.
