My post wasn’t really meant to suggest that you did let your frustration show…in fact, I was just trying to use your post as a platform for further discussion. It was more like, “this is a very interesting general point for discussion” than “kenja, you must have done this or that”.
Your post is of very widespread interest to pitchers: Do you know of a single pitcher who has never experienced frustration/anger/etc/etc from stuff that happens in baseball? Yes, position players also have these moments, but you can easily argue that pitchers are at the mercy of an umpire’s judgement on nearly every pitch that they throw.
To elaborate further on your comments, not throwing your hat or a bat, or not kicking the Gatorade bucket, or other similar behaviors…is not what I was talking about. Those behaviors are extreme and visible to everyone with eyes and they usually are dealt with by umpires or coaches very quickly.
I was trying to suggest that even some fairly subtle types of poor body language are also seen by umpires as a form of showing them up on the field–and they don’t like it. You know what I’m talking about–you thought you put a 2-2 pitch exactly where you wanted it in the zone, Blue calls “ball three”, and you stare him down for a couple of extra heartbeats…it’s not nearly as overt as throwing something or cursing out loud…but umpires see it, and they hate it.
When your catcher holds the ball for a second too long, to show the umpire that he thought your last pitch was a strike…Blues usually don’t like that too much, either.
You are much better off in the long run if you can train yourself to show no emotion whatsoever in response to any of the umpire’s game calls.
