40 years ago in the California League, when it was Advanced 'A'. We went out for pizza and beer a couple of times, and they told me a lot with a few beers in them.
Another thing about the box is it's two-dimensional. If someone like Koufax could break off a curve so hard that it was outside-outside-outside and then broke enough to catch the rear point of the plate, it't be a strike -- or, should be. But you couldn't tell that on tee vee, or even from behind the plate unless you (an umpire) had outstanding depth perception. I'd like to see close breaking stuff from an overhead camera as well as the standard view.
I could never be an umpire. I couldn't/wouldn't put up with the bullshit.
I remember Mike Winters, btw. That is, I remember he was an umpire for a long time, and I've seen him work quite a few games, including postseason. But nobody remembers much about an umpire unless they blow a big one, like Don Denkinger, or start a big hubbub, like Harry Wendlestedt. (I was watching that game and praying for a miracle for Drysdale so he could keep his shutout streak going. Wendlestedt provided it when he ruled Dick Dietz didn't try to get out of the way when Drysdale hit him with the bases loaded. Imagine that call being made today.)
