Sometimes I hear people saying, "Of course we know that umpiring is subjective to some extent. But that's what adds the precious human element to baseball!" I think that's rot. The human element in baseball should be limited to whether or not Lester can just catch the bottom of the strike zone with a diving curve, or whether or not Ortiz can get enough on that outside pitch to make it a double off the wall rather than a routine fly. If they could replace umps with robots (or, more prosaically, cameras) that got the calls right every time, I'd be all for it. That would let the real human element, that of the players, shine through.
