I like the fact that umpires vary in their viewpoint of the strike zone, as long as they are consistent about it. It reminds me of the fact that the game is played and officiated by people.

Sure, it's a shame if a poor call ruins a team's chance at winning, but I am reminded of something a coach said to me a long time ago after one of those situations:

If we needed the ump's call to win the game, then we didn't deserve to win. Bad calls happen, and they happen both ways. But you know what? Wind happens too, and so does the sun in my eyes and there isn't a *&%$^ thing I can do to change that.
